Can ABS used for 3D printing?
The Workhorse and the Warping: An Engineer’s Guide to Taming ABS There’s a material in the 3D printing world that I have a deep, complicated relationship with. It’s one of the originals, a titan of the industry that predates the desktop hobbyist revolution by decades. It’s the plastic that LEGO bricks are made from—tough, durable, […]
Can polycarbonate be 3D printed?
The Wildcat of Filaments: A Guide to Taming Polycarbonate In the world of 3D printing, we all start with the friendly housecats. PLA is docile, forgiving, and happy to curl up on just about any print bed. PETG is a bit more robust, a slightly bigger cat with more muscle, but still generally agreeable. They […]
What is the difference between CNC and laser cutting wood?
The Sculptor vs. The Surgeon: Choosing the Right Tool for Woodworking I’ve spent a quarter of a century on factory floors, surrounded by the hum of spindles and the hiss of assist gas. In that time, I’ve seen more woodworking projects succeed or fail based on one fundamental choice than any other: the choice between […]
How does a CNC machine cut metal?
The Sculptor’s Ghost: From Digital Idea to Physical Reality For twenty-five years, I’ve watched raw blocks of aluminum, steel, and titanium enter my factory and leave as mission-critical parts for aerospace, medical, and automotive applications. For the uninitiated, the process looks like magic. A solid chunk of metal is clamped into a machine, doors close, […]
What is PVA 3D printer filament?
How PVA Filament Solves Impossible Problems In my two and a half decades on factory floors, I’ve seen technologies come and go. I’ve seen hype cycles inflate and burst. But every now and then, a material comes along that isn’t just an incremental improvement; it’s a paradigm shift. It unlocks geometries that were previously confined […]
What is the purpose of knurling?
More Than Just a Pretty Pattern For the first ten years of my career, I thought knurling was simple. It was that diamond pattern you put on tool handles and thumb screws to make them grippy. You’d grab a knurling tool, jam it into a spinning part on the lathe, make a horrible noise, and […]
What is the difference between DLP and SLA?
The Light That Builds: Decoding the Resin 3D Printing Universe A junior engineer walked into my office last week, completely bewildered. He was holding two quotes for a prototype, a small, intricate medical device housing. One quote was from a service bureau using “SLA” and the other from a different bureau using “DLP.” The DLP […]
How to Select the Ideal Laser Cutter for Stainless Steel Sheets?
The Million-Dollar Mistake: Why Not All Lasers Are Created Equal Let’s get one thing straight. Asking “which laser cutter is best for stainless steel” is like asking a master chef “which knife is best.” The real answer is, “It depends entirely on what you’re trying to do.” But in the world of laser cutting, the […]
What is the difference between TIG and MIG welding?
The Hot Glue Gun vs. The Fountain Pen On any given day on my factory floor, you’ll see two welders working side-by-side, creating products that are worlds apart. One welder, let’s call him Dave, is laying down long, fast, and strong welds on a batch of heavy-duty steel utility racks for pickup trucks. There’s a […]
What is the difference between urethane casting and injection molding?
Every week, a new founder or a product designer from a Fortune 500 company walks onto my factory floor, holds up a freshly 3D-printed part, and asks the same fundamental question: “How do I make this for real?” What they’re really asking is, “What’s the next step after prototyping?” They’ve proven the shape, the fit, […]
