As Russia’s war on Ukraine drags on, its knock-on effects are being felt far beyond the eastern Europe theater. And perhaps nowhere is this more acutely felt than in the …read more Continue reading Hackaday Links: March 13, 2022

JIT vs. AM: Is Additive Manufacturing the Cure to Fragile Supply Chains?

As fascinating and frustrating as it was to watch the recent Suez canal debacle, we did so knowing that the fallout from it and the analysis of its impact would …read more Continue reading JIT vs. AM: Is Additive Manufacturing the Cure to Fragile Supply Chains?

Using Additives For Better Performing Epoxy

Epoxy resins are an important material in many fields. Used on their own as an adhesive, used as a coating, or used in concert with fiber materials to make composites, their high strength and light weight makes them useful in many applications. [Tech Ingredients] decided to explore how combining basic …read more

Additive + Subtractive = One Powerful Machine

It says it right on the title of the video below: it was bound to happen eventually. It’s only natural that somebody would stick a 3D printer extruder on the business end of a CNC machine. The long-awaited convergence of additive and subtractive manufacturing is here.

OK, that may be overstating things a bit, but we think [Chris DePrisco] is on to something here. Given the considerable investment he’s made in his DIY CNC machine, an enormous vertical machining center that looks a little like a homebrew Bridgeport, it was a no-brainer to take advantage of the huge XYZ stage. …read more

A Grenade Launcher Named RAMBO

Always one to push the envelope, U.S. Army researchers from the U.S. Army Armament Research, Development and Engineering Center (ARDEC) have been successfully experimenting with 3D printing for one of their latest technologies. The result? RAMBO — Rapid Additively Manufactured Ballistic Ordinance — a 40mm grenade launcher. Fitting name, no?

Virtually the entire gun was produced using additive manufacturing while some components — ie: the barrel and receiver — were produced via direct metal laser sintering (DMLS). So, 3D printed rounds fired from a 3D printed launcher with the only conventionally manufactured components being springs and fasteners, all within a …read more
