Product Design Tips

Every engineering team eventually runs into the same problem: a physical part exists, but no usable file for it does. A discontinued component, legacy equipment with no manufacturer support, a part that was designed by someone no longer with the company — the object is real, but there's no way to modify, reproduce, or manufacture it without starting from scratch. Reverse engineering is the process of closing that gap: turning a physical part into an accurate, editable CAD mod

A CAD model that looks correct on screen is not the same as a part that will print correctly. Between the render and the finished object sits a set of physical constraints — layer adhesion, thermal behavior, unsupported geometry — that most CAD software will not warn you about. This is the gap where prototypes fail, deadlines slip, and budgets get eaten by reprints. Below are ten design rules we apply to every file we review before it goes to print, whether it comes from a st

If you've printed enough enclosures, you've seen it happen: a perfectly sliced print finishes, looks flawless on the bed, and then twenty minutes later the corners have lifted, the walls have bowed, and what should have been a flat-sided box now looks like it's trying to curl into a smile. This is 3D printing warping, and it's one of the most common — and most misunderstood — failures in FDM printing. Most people blame the printer — a loose belt, a drafty window, "bad" filame

Snap-fit joints are one of the most useful tools in a designer's toolkit. They let you join two parts without screws, adhesives, or welds — just a bit of elastic deformation and a satisfying click. For 3D printed parts, snap-fits are especially valuable: they reduce assembly time, cut down on hardware costs, and allow enclosures or assemblies to be opened and closed repeatedly for maintenance or repair. But designing a snap-fit that actually works with 3D printing is trickier
