Every FilamentFeed story on Polymaker — news, reviews, and analysis, newest first.
San Diego County has sued Polymaker under California's Unfair Competition Law. The complaint does not argue that PLA is illegal. It argues that gun-rights branding, a firearm-focused creator and affiliate links made the filament a regulated 'firearm precursor part'.

My Tech Fun's head-to-head found desktop PC-ABS from a Prusa Core One L and Bambu Lab H2D nearly matched a six-figure Stratasys Fortus 450mc on strength and beat it on looks, with dimensional accuracy the industrial machine's only clear win.
Polymaker's new HT-PLA Pro nearly doubles notched Charpy impact strength over standard HT-PLA and boosts Z-axis layer adhesion, while still hitting 107.6°C heat deflection after annealing — at the same $25.99/kg price.
Annealing reheats a finished print near its glass transition to recrystallize the polymer, trading a little dimensional accuracy for real gains in strength and heat resistance — as Polymaker's HT-PLA Pro shows with a 30-minute, 100C cycle.
A reference guide to nozzle and bed temperatures for PLA, PETG, ABS, ASA, TPU, and nylon, drawn from manufacturer technical data sheets and enclosure/adhesion guidance.
From replacement cleats to instrument housings and full hull experiments, 3D printing is finding a permanent role in marine environments. ASA and CF-PETG are doing real work; full hull printing is closer than it sounds but further than the headlines suggest.
The K1C is Creality's answer to the question of whether a 600 mm/s CoreXY machine can handle abrasive composite filaments without constant nozzle replacement. The answer is mostly yes, with caveats that matter for serious users.
Flexible filaments are not interchangeable. TPU, TPE, and TPC differ substantially in hardness, chemical resistance, print temperature, and long-term fatigue behavior. Choosing the wrong one means a part that either fails in service or was never printable in the first place.
Matte PLA and PETG reduce layer-line visibility, photograph better under broad lighting, and hide fingerprints. Here's how the finish is produced and where it makes sense.
At 300+ mm/s, standard PLA becomes the bottleneck — not the motion system. High-flow filaments are formulated to melt faster, enabling speed printers to reach their actual potential.
Budget filament has improved dramatically. These are the brands and specific spools worth buying at the low end of the market — and the ones that waste your time despite the low price.
