The perpetual joke-turned-technical-challenge of running Doom on inappropriate hardware has found its way to the Prusa Core One, courtesy of Nils_N3DP on Reddit. Posted to the r/prusa3D subreddit and documented on Instagram, Nils' effort crammed the first level of the timeless, OG boomer-shooter onto their custom inverted-color Core One (which is itself a marvel – check it out).

But getting one on virtually any filament you could want? That's the rare feeling of a Polymaker Restock sale. Right now, and running through to July 5, 2026, you can grab deals sitewide, like 1 kg spools of Panchroma CoPE for $13, or, a rarer sight, Polymaker's nifty modular PolyDryer drybox system at 20% off.

3D printed bike saddles are practically mainstream now, so it was only a matter of time before 3D printed padding came for cycling shorts. The new Aura N3X FL from Elastic Interface is a digitally engineered, 3D printed, open-geometry padding insert to improve ventilation, pressure distribution, and long-ride support. Designed as a component for cycling-apparel brands — rather than a finished pair of shorts — these could soon be turning up inside your favorite cycling shorts, giving 3D printing another intimate assignment.

Relativity Space is heading to Mars, well, its hardware is. NASA has picked the California-based 3D printed rocket maker to deliver its Aeolus science instruments to the Red Planet in 2028. Relativity will handle the rocket, spacecraft, cruise, and mission management, while NASA’s instruments study Martian winds, dust, clouds, and temperatures to help make future landings less of a white-knuckle affair.

With more filament brands phasing it out in favor of ASA as the better, safer alternative, the answer for most is probably "not recently."

We don't really use ABS much in the All3DP print lab anymore, and a poll we conducted about the best-selling materials across dozens of brands placed ABS nowhere on the list. Today, it's a hyper-niche holdout – a long way from its abundance in the early days of desktop 3D printing.
