What is Binder Jetting? Process, Benefits, and Applications
Binder jetting (BJ) is a versatile additive manufacturing technology that is used to print polymer, metal, ceramic and sand parts. The Binder jetting 3d printing technology uses powdered materials upon which the print head selectively deposits a liquid binding agent (binder) to fuse adjacent powdered particles together to form a bond. It can be understood better by considering it a mix of powder bed fusion and material jetting technologies in a way that it uses powdered material and also uses a binder......

Does 3D Printer Filament Go Bad? Shelf Life Explained
If you’ve been 3D printing for more than a few months, you’ve probably got a little “filament graveyard” in your workspace. Half-used spools, bargain-bin rolls you bought on sale, maybe even that neon green PLA you swore you’d use for something. But, how long can that stuff actually sit before it goes bad? Some filaments are surprisingly tough. PETG, for instance, will fight humidity longer than you think. PLA, on the other hand? Leave it out for a year in a humid room and you’ll have brittle spaghett......

Binder Jet 3D Printing: Complete Technology Guide
What is Binder Jetting 3D Printing? Understanding the Basics Binder jetting is often compared to inkjet printing, but on steroids. Instead of spraying ink on paper, the machine lays down a liquid binder onto a thin layer of powder. Each sweep of the print head sticks particles together, one layer at a time, until you’ve got what’s called a “green part.” Once it’s out of the machine, the loose powder is blown or brushed away, and the part usually needs curing and then sintering or infiltration to get i......

What is Material Jetting 3D Printing | The Complete Guide
So, what exactly is material jetting additive manufacturing? It’s like those office inkjets, only this one’s built for serious work. Instead of laying down ink on paper, it shoots out tiny drops of liquid photopolymer onto a flat platform. A quick flash of UV light locks each pass in place. Layer after layer, the shape takes form until you’re holding a finished part. What makes it shine are the little things, sharp edges, clean surfaces, and the ability to blend materials in a single build. Material J......

How to Get Better Overhangs in 3D Printing - Complete Fix Guide
Why 3D Printing Overhangs Matter (and Why They’re So Frustrating) (Source: ABCD4WS via Reddit) Ever printed a model and noticed parts drooping, curling, or turning into stringy disasters mid-air? That’s an overhang issue. Overhangs are parts of a print that jut out beyond previous layers, meaning they have little to no material beneath them for support. If not handled properly, they result in poor surface quality, failed prints, or ugly warped edges. Real-World Example: Say you’re printing a figurine ......
