A Brief Look at Desktop and Industrial FDM 3D Printing

Posted On May 26, 2022 By Protolabs
There’s one of only a few 3D printing processes that is possible at both a desktop- and industrial-level. It’s fused deposition modeling (FDM), although you’ll sometimes see it referred to as fused filament fabrication (FFF). It’s a great printing process to create prototype parts to test fit and form. Because it prints using thermoplastic material, it also delivers parts that are functional when in a high-heat environment, or when exposed to chemicals or mechanical stress.

Tips for Threading and Adding Inserts in 3D Printing

Posted On May 20, 2022 By Rachel Hunt
There’s one fundamental thing you need to know about threading and assembling inserts into 3D-printed parts: What you can and can’t manufacture depends on the material properties of both the part and the insert. A second thing to keep in mind: It pays to design for standard taps and inserts whenever possible.

Fillets and Chamfers: Getting Edgy with Machining

Posted On May 16, 2022 By Protolabs
A newly machined metal part can end up with edges that are sharper than desired for the end user unless the design smooths or breaks those sharp edges. To create an edge break, the design should incorporate sloped or beveled edges and corners known as chamfers—or rounded ones called fillets.

How to Avoid ‘Over-Engineering’ Your Next Part Design

Posted On April 25, 2022 By Protolabs
When you hear the term “over-engineering,” you probably think about all of those overly complicated products we’ve all encountered that seem too complex relative to their intended use. The confusing shower faucet controls. The washer or dryer with a dizzying array of counter-intuitive buttons and settings. Your new car’s baffling audio setup. Well, you get the idea.
