What 3D Printing Software Is Used? A Complete Guide

So, you have a 3D printer, or you’re about to get one. You’ve seen the incredible things it can create—custom tools, intricate miniatures, and practical household fixes. You’re ready to turn your own ideas into reality. You open your laptop, head to Google, and type the most logical question in the world: “What software do I need for 3D printing?”

This is where the journey for many aspiring makers hits its first, and most confusing, roadblock. The search results are a blizzard of names: Tinkercad, Blender, Fusion 360, Cura, PrusaSlicer. You were looking for one program, but you found a dozen. It feels overwhelming, and it’s easy to assume this is far more complicated than you bargained for.

Here is the single most important thing to understand: There is no single “3D printing software.”

Instead, there is a 3D printing software workflow—a three-stage digital assembly line that takes an idea from a spark in your imagination to a solid object in your hand. Each stage requires a different type of software, each with a specific and crucial job to do. Understanding this three-stage process is the key that unlocks everything. It transforms that confusing list of names into a logical toolkit.

In this comprehensive guide, we will walk through that entire workflow. We will demystify each stage, explaining in simple terms what the software does and why you need it. We will then take a deep dive into the most popular, powerful, and beginner-friendly programs on the market today—with a heavy focus on the free tools that can take you from absolute novice to advanced designer.

First, we will build our foundational understanding by defining the three distinct software worlds: the world of creation (3D Modeling), the world of translation (Slicing), and the world of execution (Printer Control). Then, we will put the most popular 3D modeling tools in a head-to-head showdown, complete with a detailed comparison table, to help you choose the perfect one for your goals. Finally, we’ll explore the unsung hero of the process—the slicer—and tie it all together with a practical, step-by-step guide to your very first print.

The Three Software Worlds of 3D Printing

Forget specific brand names for a moment. To truly understand the landscape, you need to think in terms of function. Every single 3D printed object, from a simple cube to a complex jet engine turbine, must pass through these three digital stages.

Stage 1: The Dream – 3D Modeling Software (CAD)

This is the very beginning of the journey. It’s the blank canvas, the digital clay, the architect’s drafting table. 3D modeling software is where your idea is given digital form. If you want to create something original that doesn’t already exist, you will spend most of your time in this type of program.

Its job is simple to describe but infinitely deep in practice: to create a three-dimensional geometric model and save it as a file (most commonly an STL, OBJ, or 3MF file).

Think of this as writing the architectural blueprint for your object. You define its shape, its dimensions, its holes, its curves, and its angles. There are many different ways to do this, from sticking virtual blocks together to sculpting digital clay or drafting precise engineering plans, which is why there are so many different 3D modeling programs.

• Key Function: Creating a 3D model from scratch or modifying an existing one.
• Input: Your ideas, mouse clicks, and keyboard commands.
• Output: A 3D model file (e.g., MyAwesomeDesign.stl).
• Popular Examples: Tinkercad, Fusion 360, Blender, FreeCAD.

(Note: If you are only ever printing files that other people have designed and shared on sites like Thingiverse or Printables, you can technically skip using this software yourself. But the moment you want to change something or create your own design, this is your starting point.)

Stage 2: The Translation – Slicer Software

You’ve designed a beautiful 3D model. It’s a perfect digital blueprint. But your 3D printer has no idea what an STL file is. It’s like handing a brilliant novel to someone who can’t read. Your printer doesn’t think in terms of solid objects; it thinks in terms of coordinates, temperatures, and movements. It needs a translator.

This is the job of the slicer. The slicer is the indispensable middle-manager of the 3D printing world. It takes the 3D model you created and translates it into a language your printer can understand.

Its job is to “slice” your 3D model into hundreds or thousands of thin horizontal layers and generate the specific, line-by-line machine instructions (called G-code) for the printer to follow.

This G-code file is a highly detailed recipe. It tells the printer everything: what temperature to set the nozzle, how fast to move, where to start printing the first layer, how to draw the outline, how to fill it in, when to lift the nozzle, move to the next layer, and repeat the process until the object is complete. It’s also where you, the user, make critical decisions about the print itself—how strong it should be (infill), how detailed it should look (layer height), and whether it needs temporary scaffolding (supports).

• Key Function: Converting a 3D model file into printable G-code.
• Input: A 3D model file (MyAwesomeDesign.stl).
• Output: A G-code file (Print_MyAwesomeDesign.gcode).
• Popular Examples: Ultimaker Cura, PrusaSlicer, Creality Slicer.

Stage 3: The Control – Printer Interface Software

You have your G-code recipe. Now, you just need to get it to the chef—your 3D printer. Printer interface software is the communication link between your computer and the printer.

Its job is to send the G-code to the printer and allow you to monitor and control the printing process.

In the early days of desktop 3D printing, this was always a separate program (like Pronterface or Repetier-Host) that you would run on a computer tethered to your printer via a USB cable. It provided a dashboard where you could manually heat the nozzle, move the axes, start the print from the G-code file, and watch its progress.

Today, this stage has become much more streamlined and is often “invisible.”

• The SD Card/USB Drive Method: The vast majority of beginners will simply save the G-code from their slicer onto an SD card or USB drive, walk it over to the printer, and start the print using the printer’s built-in screen and controls. In this case, the printer’s own firmware is acting as the interface.
• Integrated Slicer/Control: Some software, like the UltiMaker Digital Factory, combines slicing and printer control into a single, cloud-based ecosystem.
• Advanced Control: Power users often use a dedicated mini-computer (like a Raspberry Pi running OctoPrint) connected to their printer. This creates a powerful web interface, allowing them to upload G-code, start, stop, and monitor prints remotely from any device on their network.

For the purpose of this guide, we will focus on the first two stages—Modeling and Slicing—as this is where you will be making the active software choices that define your 3D printing experience.

This is where you decide on your primary tool. It’s the digital equivalent of a sculptor choosing their clay, a painter choosing their brushes, or an engineer choosing their drafting instruments. The software you choose will fundamentally shape what you can create and how you create it.

The sheer number of options can feel paralyzing. Blender, Fusion 360, Tinkercad, FreeCAD, SketchUp, ZBrush… the list goes on. But here’s the secret: you don’t need to learn them all. You just need to find the one that matches your goals. The key is to understand that these programs are built on different philosophies, or “modeling paradigms,” designed for different tasks.

To find the right tool for you, we need to answer one simple question: What do you want to make?

• Are you looking to design functional parts—brackets, enclosures, gears, and custom mechanical pieces where precision is everything?
• Are you hoping to create artistic, organic models—characters for tabletop games, detailed sculptures, and natural, flowing shapes?
• Are you an absolute beginner who just wants to get a feel for 3D design without being overwhelmed by a complex interface?

Your answer will point you directly to the perfect category of software. In this section, we will explore the three main paradigms of 3D modeling, highlight the champion software in each category (with a focus on free and accessible options), and provide a detailed comparison table to help you make your final choice.

For the Absolute Beginner: Direct Modeling with Tinkercad

If you are new to 3D design, if the thought of complex menus and dozens of tools makes you anxious, or if you simply want to start creating something right now, then your journey begins with Tinkercad.

Tinkercad is not just a piece of software; it’s a masterpiece of user-friendly design. It’s a free, browser-based tool from Autodesk (the makers of professional-grade software like AutoCAD and Fusion 360) designed specifically to be the most accessible entry point into 3D modeling. Its entire philosophy is built around a concept a child can understand: combining simple shapes to create complex ones.

The Core Concept: Digital Lego
Imagine a box of digital Lego bricks. You have cubes, spheres, cylinders, cones, pyramids, and more. To create something, you simply drag these shapes onto your workplane, move them around, resize them, and combine them. To make a hole, you don’t use a complex “cut” tool; you simply grab a shape that is designated as a “hole,” place it where you want the cut to be, and group the two objects. It’s an incredibly intuitive and powerful system.

Who Is It For?

• Absolute Beginners: It is, without question, the best first step for anyone of any age.
• Educators and Students: Its simplicity and browser-based nature make it a classroom favorite.
• Hobbyists Designing Simple Functional Prints: Need to design a custom box for a project, a simple bracket, or a nameplate? Tinkercad is often the fastest way to get it done.

Why We Recommend It (Pros)

• Zero Cost: It is completely free to use. All you need is a web browser and an internet connection.
• Incredibly Easy to Learn: Most people can learn the fundamentals and design their first printable object in under an hour. The built-in tutorials are excellent.
• No Installation Required: Because it runs in your browser, it works on almost any computer (Windows, Mac, Linux, even Chromebooks) without any software to install. Your projects are saved to the cloud, accessible from anywhere.
• Surprisingly Capable: While simple, it’s not a toy. You can import existing shapes (like SVGs for logos or STLs for modifications) and create surprisingly complex and precise models by cleverly combining the basic primitives.

Its Limitations (Cons)

• Not for Complex Organic Shapes: Trying to sculpt a detailed character face or a flowing, natural object in Tinkercad would be an exercise in frustration. It is built for geometric, not organic, design.
• Lacks Advanced Tools: It has no concept of parametric design, advanced filleting, or complex surface modeling. As your ambitions grow, you will eventually hit a ceiling.
• Requires an Internet Connection: As a cloud-based application, it won’t work offline.

Your First Project Idea: Design a personalized keychain. Start with a simple base shape (like a rectangle or circle), drag letter shapes to spell out your name, group them together, and add a hole for the keyring. It’s a classic “first print” that teaches you all the core skills.

For the Engineer & Designer: Parametric Modeling with Fusion 360

At some point, you will want to design a part that needs to be perfect. A bracket that has to fit onto another object with millimeter precision. An enclosure for an electronic board where every hole must align exactly. A mechanical part that needs to be easily modified later. For this, you need to graduate from direct modeling to parametric modeling. And the undisputed king of accessible parametric modeling is Autodesk’s Fusion 360.

The Core Concept: A Design with a Memory
Imagine building a house of cards. If you want to change a card at the bottom, the whole structure collapses. This is like direct modeling (Tinkercad). Now, imagine building a house with an architectural blueprint that records every single step: “Lay foundation,” “Erect south wall,” “Cut window at 3 meters high.” If you want to change the window height, you don’t knock the wall down; you simply go back to the blueprint, change the number from “3” to “4,” and the model automatically rebuilds itself with the correct dimensions.

This is parametric modeling. Every action you take—creating a sketch, extruding a shape, cutting a hole, rounding an edge—is recorded in a timeline at the bottom of the screen. Your design is not just a “dumb” shape; it’s a smart, editable recipe. You can go back in time to any step, change a dimension (a “parameter”), and the rest of your model will update accordingly. This is an absolute game-changer for designing functional, mechanical parts.

Who Is It For?

• Hobbyists and Makers: Anyone designing functional parts for their projects, from drone frames to custom robotic components.
• Inventors and Entrepreneurs: Perfect for prototyping new products.
• Engineers and Product Designers: It is a professional-grade tool used in industries worldwide.
• Tinkercad Graduates: It’s the logical next step when you feel constrained by Tinkercad’s limitations.

Why We Recommend It (Pros)

• Extremely Powerful: It’s a full-featured, professional CAD (Computer-Aided Design) suite. It can handle incredibly complex mechanical assemblies, perform stress simulations, and even generate toolpaths for CNC machining.
• Free for Hobbyists and Startups: Autodesk offers a generous free license for personal, non-commercial use, which includes the vast majority of its features.
• Excellent for Precision: The entire workflow is built around creating precise 2D sketches and turning them into 3D objects, ensuring your parts are dimensionally accurate.
• Great Community and Learning Resources: There is a massive community of users and an endless supply of high-quality tutorials on YouTube to help you learn.

Its Limitations (Cons)

• Steeper Learning Curve: While more intuitive than older CAD software, Fusion 360 is a complex program. Expect to spend several hours learning the basic workflow and many more to become proficient.
• Cloud-Based and Subscription-Oriented: Like Tinkercad, it is cloud-centric and requires an internet connection to work in its default mode (though it has an offline mode). The free license terms can also change over time.
• Not Ideal for Artistic Sculpting: Using Fusion 360 for organic sculpting is like trying to paint a portrait using a graphing calculator. It can be done, but it’s the wrong tool for the job.

An Open-Source Alternative: For those who prefer to avoid cloud-based software or subscription models, FreeCAD is an incredibly powerful, completely free, and open-source parametric modeler. While its interface is generally considered less polished and its learning curve can be steeper than Fusion 360’s, it is a fantastic piece of software that runs entirely on your local machine.

For the Artist & Sculptor: Mesh & Sculpting with Blender

What if you don’t care about perfect right angles and precise dimensions? What if you want to create a snarling dragon, a lifelike human face, or a flowing, elegant sculpture? For this, you need a completely different approach: digital sculpting. And the undisputed king of free and open-source sculpting is Blender.

The Core Concept: Digital Clay
Imagine you have a lump of digital clay on your screen. You have a suite of tools that can pull, push, pinch, smooth, inflate, and carve this clay, just like a real sculptor. You are not constrained by dimensions and sketches; you are working directly with the surface of a “mesh” (a collection of vertices, edges, and faces) to shape your vision in a fluid, intuitive way.

Blender is a behemoth. It is a complete 3D creation suite used by professional artists to create animated films (including several of their own open-source movies), visual effects, and video game assets. But for the 3D printing community, its Sculpt Mode is a primary draw.

Who Is It For?

• Digital Sculptors and Artists: Its primary audience.
• Tabletop Gaming Enthusiasts: Designing and customizing miniatures for games like Dungeons & Dragons.
• Character Designers: Creating organic characters and creatures.
• Anyone Making Non-Geometric Models: Jewelry, decorative art, and other free-form objects.

Why We Recommend It (Pros)

• Completely Free and Open Source: Blender is free for everyone, for any purpose, forever. It is a testament to the power of community-driven development.
• Unbelievably Powerful: Its capabilities are staggering and rival those of software costing thousands of dollars. From modeling and sculpting to animation, rendering, and video editing, it can do it all.
• The Ultimate Tool for Organic Shapes: The sculpting toolset is world-class, giving you complete freedom to create any organic form you can imagine.
• Massive Community and Tutorials: Blender has one of the largest and most passionate online communities. Whatever you want to learn, there are hundreds of tutorials available.

Its Limitations (Cons)

• The Steepest Learning Curve: Blender is famously complex. While it has become much more user-friendly in recent years, a beginner opening it for the first time will likely feel completely lost. It requires a dedicated effort to learn.
• Not a Precision Tool (by Default): It is not a parametric CAD program. While you can create precise models and there are add-ons to improve its CAD capabilities, its core strength is not in creating dimensionally-driven mechanical parts.
• Can Be Overkill: If all you want to do is design a simple bracket, opening Blender is like using a sledgehammer to crack a nut.

With your modeling software chosen and your first STL file created or downloaded, you have completed the first, most creative stage of the workflow. You have your digital blueprint. But as we discussed, this blueprint is unreadable by your printer. Now, you need the translator. You need the unsung hero of the entire 3D printing process.

You now have your digital blueprint. But this blueprint, a beautiful and complex mesh of triangles, is still just a “dumb” solid. Your 3D printer, a machine that thinks in coordinates and step-by-step commands, has no idea what to do with it. It cannot understand the concept of a solid object. It only understands a language of movement, temperature, and extrusion.

To bridge this crucial gap, we need a translator. We need the unsung hero of the entire 3D printing process, the software that turns your “what” into a precise “how.” We need a slicer.

The Slicer: From 3D Model to Machine Instructions

If your 3D model is the architectural blueprint, the slicer is the general contractor, the foreman, and the entire construction crew rolled into one. It is arguably the most critical piece of software in the entire workflow because its settings have a direct and dramatic impact on the quality, strength, and speed of your final print.

The core concept is brilliantly simple. A slicer takes your 3D STL file and digitally “slices” it into hundreds or thousands of thin, horizontal 2D layers. Then, for each layer, it generates a precise toolpath—a set of instructions telling the printer exactly where to move the print head, how fast to go, and how much filament to extrude. This sequence of instructions is saved as a file format called G-code, the universal language of CNC machines, including 3D printers.

Choosing a slicer is less about finding different features and more about preferring a certain workflow, interface, and community. The good news is that the best and most popular slicers in the world are completely free.

• Ultimaker Cura: This is the most widely used slicer on the planet. It’s open-source, supports a massive library of pre-configured printer profiles, and is known for being both beginner-friendly and incredibly powerful under the hood. It’s the de facto standard for many.
• PrusaSlicer: Originally a fork of another open-source slicer, PrusaSlicer has evolved into a powerhouse. It’s known for its clean interface, cutting-edge features (like organic “tree” supports and variable layer heights), and excellent default profiles, especially for Prusa printers (though it works with any printer).
• Bambu Studio: A newer player, this slicer is a fork of PrusaSlicer but is specifically designed for the high-speed Bambu Lab printers. It integrates cloud printing and advanced features tailored to their ecosystem.

While there are other options, 99% of hobbyists and professionals will use one of these three. The key isn’t which one you pick, but how you use it. To do that, you must understand the settings that truly matter.

The Critical Slicer Settings You Must Understand

When you first open a slicer, you’ll be greeted by dozens, if not hundreds, of settings. It’s overwhelming. The secret is that you only need to master a handful of them to control 90% of your print’s outcome.

Layer Height: The Resolution of Your Print

This is the single most important setting for determining the visual quality of your print. It defines the thickness of each individual layer. A smaller layer height means more layers are needed to build your object, resulting in a smoother, more detailed surface finish where the layer lines are less visible. A larger layer height means fewer layers, a much faster print, but more pronounced layer lines.

• Standard Quality (0.20mm): This is the default for most printers and a perfect balance of speed and quality for functional parts.
• High Quality (0.12mm): Use this for miniatures, display pieces, or models with fine surface details. Be prepared for print times to double or even triple.
• Draft Quality (0.28mm – 0.32mm): Use this for rapid prototyping, where you just need to check the size and fit of a part and don’t care about its looks.

Infill: The Skeleton of Your Print

Your 3D prints are rarely solid plastic. Printing a solid object would take a huge amount of time and material. Instead, the slicer creates a solid outer shell (defined by the “wall” or “perimeter” settings) and fills the inside with a low-density structure called infill.

The infill setting has two parts: density and pattern.

• Infill Density (%): This determines how much plastic is used for the internal structure.
  • 10-20%: Perfect for most decorative models. It provides enough support for the top surfaces to print cleanly without wasting material.
  • 25-50%: Use this for standard functional parts that need to withstand some stress, like brackets or enclosures.
  • 50-100%: Reserved for parts that need to be extremely strong and rigid. A 100% infill print is a solid object.
• Infill Pattern: This is the geometric shape of the internal structure. While there are many, the most common are:
  • Grid/Lines: Fast to print and good all-around.
  • Cubic/Gyroid: More complex patterns that provide excellent strength in all directions. Gyroid is a fan favorite for its strength and unique, wavy look.

Supports: The Scaffolding for Your Print

A 3D printer works by laying down molten plastic on top of the previous layer. This means it cannot print in mid-air. Any part of your model that juts out at a steep angle or has no material directly beneath it is called an “overhang.” To print these features, the slicer must generate temporary, disposable vertical pillars called supports.

Understanding supports is a critical skill.

• When are they needed? The general rule of thumb is that most printers can handle overhangs up to about 45-50 degrees from vertical without supports. Anything steeper than that will require them.
• Types of Supports:
  • Standard/Normal Supports: These are simple, grid-like vertical pillars. They are easy to generate but can sometimes be difficult to remove and may leave marks on the surface they touch.
  • Tree/Organic Supports: A more advanced option where the supports grow like tree branches, starting from the build plate and reaching up to touch only the specific points on the model that need it. They use less material and are often much easier to remove, leaving a cleaner surface finish.
• The Downside: Supports add significant time to your print, use extra material, and require post-processing to remove. A key part of becoming an expert is learning how to orient your model on the build plate to minimize the need for supports.

Build Plate Adhesion: The Foundation of Your Print

The single most common cause of a failed 3D print is a bad first layer. If the first layer of plastic doesn’t stick firmly to the build plate, the entire print is doomed. To help ensure a strong foundation, slicers offer several adhesion assistance tools.

• Skirt: A thin outline drawn around the part, but not touching it. Its main purpose is to prime the nozzle and get the filament flowing smoothly before it starts printing your actual model. It’s a good idea to use a skirt on every print.
• Brim: A series of concentric lines that attach directly to the outer edge of your model’s first layer, creating a wide “brim” around it. This increases the surface area of the first layer, providing a much stronger grip on the build plate. It’s excellent for tall, thin models or parts with sharp corners that are prone to warping and lifting off the bed.
• Raft: An entire disposable platform of plastic that is printed first. Your model is then printed on top of this raft instead of directly on the build plate. Rafts provide the absolute best adhesion but use a significant amount of material and time, and the surface that touches the raft will not be as smooth. They are typically used for difficult materials or models with a very tiny first-layer footprint.

The Final Step: The Printer Interface & Control Software

Once your slicer has worked its magic and generated the G-code file, you’ve reached the final stage: sending the instructions to the printer and monitoring the process. This is the role of the control software or printer interface. There are three primary ways to do this.

The Low-Tech Way: SD Card / USB Drive

This is the simplest and often most reliable method. You save the G-code file from your slicer onto an SD card or USB drive, physically walk it over to your printer, insert it, select the file using the printer’s built-in screen and controls, and press “Print.”

• Pros: Extremely reliable. The printer is a self-contained unit, and your print will not fail if your computer goes to sleep or crashes.
• Cons: It’s a manual process (the “sneakernet”). You have no remote control or monitoring capabilities.

The Tethered Way: Direct USB Connection

Most printers have a USB port that allows you to connect them directly to your computer. Using software like Pronterface, or even built-in features in some slicers, you can send the G-code to the printer and control it directly from your PC.

• Pros: Gives you real-time control and feedback from the printer.
• Cons: A major liability. If your computer decides to run an update, goes to sleep, or the USB cable gets disconnected, your hours-long print will fail instantly. This method is generally not recommended for long prints.

The Smart Way: Network & Web Interface

This is the modern and most powerful way to control your printer. It involves connecting your printer to your home network, usually by plugging a small single-board computer like a Raspberry Pi into your printer’s USB port. This tiny computer runs a dedicated print server software.

The most famous of these is OctoPrint. OctoPrint creates a web interface that you can access from any device on your network (your computer, phone, or tablet). You can upload G-code files remotely, start and stop prints, monitor temperatures, and, most importantly, connect a small camera to watch your prints live from anywhere. It’s a massive quality-of-life improvement. Newer firmware like Klipper uses similar web interfaces (Mainsail, Fluidd). High-end consumer printers, like those from Bambu Lab, have this functionality built-in via their cloud service.

The Complete Software Ecosystem: Your Path Forward

We’ve covered the entire digital journey, from the spark of an idea to a physical object. It’s a three-stage workflow, and understanding the role of each stage is key to success.

• Stage 1: Modeling (The Idea): You create a 3D shape.
• Stage 2: Slicing (The Plan): You translate that shape into layer-by-layer instructions.
• Stage 3: Controlling (The Execution): You send those instructions to the machine.

For the Absolute Beginner, the path is clear:

1. Modeling: Start with Tinkercad in your web browser.
2. Slicing: Download Ultimaker Cura and use its default profiles.
3. Controlling: Use an SD card to transfer the file.

This simple, robust workflow is how millions of people have started their 3D printing journey. As your skills and ambitions grow, you can advance each stage independently.

• When you need to design more precise, functional parts, you graduate from Tinkercad to Fusion 360.
• When you want more granular control over your print quality and features, you explore the advanced settings in Cura or switch to PrusaSlicer.
• When you get tired of running back and forth with an SD card, you set up OctoPrint for remote control and monitoring.

The software is the brain of the 3D printing process. By understanding this ecosystem, you are no longer just a user; you are a creator in full control of the incredible power to turn your digital dreams into physical reality.

Frequently Asked Questions (FAQs)

What is the best 3D printing software for beginners?

For a complete beginner, the best software combination is Tinkercad for 3D modeling and Ultimaker Cura for slicing. Tinkercad is browser-based, incredibly easy to learn, and perfect for creating simple geometric shapes. Cura has a user-friendly interface with reliable pre-set profiles for almost every popular 3D printer.

Do I need to pay for 3D printing software?

No. The vast majority of the best and most popular software for hobbyist and even professional 3D printing is completely free. Tinkercad, Blender, Cura, and PrusaSlicer are all free. Fusion 360 offers a very generous free license for personal, non-commercial use. While paid professional software exists, you do not need it to get started or even to produce professional-quality results.

Can I just download models instead of designing them myself?

Absolutely. There is a massive ecosystem of websites dedicated to sharing 3D models. Sites like Thingiverse, Printables.com (from Prusa), and MyMiniFactory host millions of free STL files that you can download and print. Even if you don’t design your own models, you will still need a slicer (like Cura or PrusaSlicer) to prepare those files for your specific printer.

What’s the difference between CAD software and a Slicer?

CAD (Computer-Aided Design) software is used to create or modify a 3D model (the digital blueprint). Examples include Fusion 360 and Tinkercad. A Slicer is used to prepare that finished 3D model for printing by cutting it into layers and generating the G-code instructions that the printer understands. You need both types of software, but they perform two very different, sequential tasks.
