Color Commentary
Markforged is looking on the bright side — literally.

Despite being acquired twice in the past 14 months, the company is still innovating and releasing new products, specifically, four new cheerful colors of its signature Onyx GF, a chopped glass fiber-filled nylon exclusively for its FX-series industrial 3D printers. Designed for color-coded tooling, fixtures, and safety indicators, the material embeds color directly into the filament so there's no more painting or labeling. Onyx GF also comes in new white and grey. We're excited to see Markforged in the capable hands of Stratasys with that deal officially closing soon.

Flex Appeal
Prusa's new black TPU 95A gets a little black-tie galaxy glitter.

This new filament is the company's Jet Black TPU in evening wear because sometimes your RC tires, phone cases, and bendy little shock-absorbing bits deserve to feel like they’re walking a red carpet. The new Prusament PTU Galaxy Black filament keeps the serious stuff under the sparkle, including Prusa’s in-house production and tech specs, plus refill-friendly NFC-tagged spool, and costs $37.99/500g — a small price to pay for adding just enough bling to make your functional parts whisper, “I’m not like the other black filaments.”

PLAying Safe
Raising standards in the name of safety is something to be celebrated.

UK-based Filamentive has announced that its PLA and PLA Matte filaments are now EN 71-3 + A2:2024 compliant, certifying them safe regarding the leaching of regulated elements should they be ingested or come into contact with children.

The news also serves as a reminder that the devil is in the detail with such things. The raw material is certified safe, but prints from it (which introduce the variables of specific printing parameters, environment, geometry, etc.) aren't, unless independently tested. As a starting point though, hats off to them.

Good News, EUveryone
Polymaker has just launched official stores in select EU territories,

offering 20% off plus free shipping through the end of March. Great news for filament fans in Czechia, Germany, Poland, France, Spain, and the UK (UK store launching early March).

In addition to the benefit of quicker, local shipping, buying direct gives you the chance to earn savings through the company’s PolyCoins reward scheme and, crucially, save big in the Restock Day sales, which typically see up to 35% off sitewide.

The grand opening discount stacks with Polymaker's bundle builder discount (I checked) so you can potentially save 35% already if you order 10 spools or more.
