Stock Alert
It’s not all happening at Amazon today.

Polymaker’s wild Restock Day sale is also live, knocking a blanket 35% off sitewide - no coupon code necessary. On top of that, the manufacturer is offering free shipping and 5% cashback on orders.

Napkin math tells me you'd be looking at savings of over $70 on ten spools of Panchroma Matte PLA, or over $100 off a 3 kg spool of Fiberon PPS-CF10, for example. If you were planning to stock up on filament anytime soon, this is the time, and Polymaker is the place. Until October 10, that is. That’s when the sale ends.

Custom Colors
Formlabs offers the entire visible spectrum of resin colors, then finds that customers wanted a box of crayons.

After granting its Form 4 users in the U.S. the god-like power to 3D print in any custom color imaginable, Formlabs CRO Nick Graham says customers were crippled by the sheer tyranny of the RGB spectrum: "Customers gave us the feedback that they would prefer some standard options to get them started." Formlabs has now rolled out a 16-pack of pre-selected "classic colors."

Weekend Poll
Bambu Lab opened its first physical store this week.

You can read about it here, but the event got me thinking. Even though a physical "flagship" store still has to turn brisk business to justify itself (it's not just a marketing exercise) is there even much demand for in-person printer shopping?

I sit behind a keyboard for my job, so it's easy for me to assume that no, it's all internet-based, since that's all I see. But a recent reader survey in PC Mag of brick-and-mortar tech stores placed Micro Center top of the pile. And they sell 3D printers, filaments, accessories... the lot. So tell me, where do you buy your 3D printing gear?

Crash Test Winner
Which infill pattern enhances the crashworthiness of your 3D printed parts?

In a new study, which may not come as a surprise to veteran makers, the cubic-subdivision won out over the octet, gyroid, grid, and concentric, among five others, as the infill that had the highest energy absorption efficiency due to its desirable "progressive folding" failure mode. This ensures that parts, like helmets, can absorb a maximum amount of energy while transmitting the minimum amount of peak force. Researchers used glass-filled PLA.

Elegoo Releases Centauri Carbon Firmware Code, But Questions Remain

Under pressure from groups seeking transparency about the Centauri Carbon’s underlying software, Elegoo has published the “source code” for the Elegoo OS the printer uses. The release is a positive step, but appears to validate concerns that the firmware is a heavily modified version of Klipper that breaches license conditions.

Would you “adopt” a lamp with a past life as packaging?

If your 3D printing game gets strong enough, you, too, could be turning plastic bottles into $458 designer lamps. That’s exactly what Swedish studio Manu has done with its new line Teen Jane. Printed from recycled PET, each lamp comes with an “adoption” certificate, charmingly noting its past life as humble packaging. And thanks to a built-in dimmer, the lamp doesn’t just light up a room—it sets the mood. Eco-chic never looked this luminous.

Print-Only Al
The problem wasn't the 3D printing method, it was the material.

The potential for lighter weight, more efficient rocket engines and auto parts through 3D printing aluminum has always been there. The problem was trying to 3D print with traditional alloys that tended to crack. Additive-specific aluminums are surfacing from a range of material providers and the latest, DuAlumin-3D, retains its microstructural stability up to 400ºC — the highest of any known aluminum alloy. Scientists are now looking at specific automotive applications for this 3D printed aluminum.

Diplomacy 101: Check local firearm laws before gifting 3D printed pistols.

Because nothing says "let's cooperate on international law" like gifting illegal firearms to senior foreign officials, FBI Director Kash Patel presented 3D printed guns to high-ranking New Zealand bureaucrats, according to an Associated Press report. After regulators determined the plastic replica pistols were "potentially operable", which is bureaucrat-speak for "dangerously close to being actual guns", they were swiftly destroyed. Patel was in New Zealand to open the FBI’s first standalone office there.
