Tom's Hardware gave the Prusa CORE One+ INDX a 4.5/5 Editor's Choice, praising a wiper-based toolchanger that purges just ~13mg of filament per color swap — no prime tower required — for $2,249.
Read the story →Prusa Research's second public alpha of the ground-up PrusaSlicer 3.0 rebuild squashes the most common alpha11 crashes and adds per-extruder overrides, a camera toggle, and safer 3MF re-imports.
Tom's Hardware's hands-on review of the Prusa/Bondtech INDX toolchanger on the CORE One+ Gen 2 finds induction-heated, purge-tower-free 8-color printing at Core-XY speed — for a real-world $2,249.
A Texas jury found Bambu Lab's X1, P1 and A1 printers willfully infringed four Stratasys patents on prime-tower purging and bed leveling, awarding $27.6 million — with a second, potentially bigger trial still to come.
Tom's Hardware calls the Prusa CORE One L+ update "small, but important" and awards Editor's Choice for a factory nozzle wiper and GT1.5 belts, available as a $25 retrofit, though the review's own pricing is inconsistent.
Prusa's new actively foaming PLA prints up to 65% lighter and stretches a spool 2-3x, but it demands a 0.45 extrusion multiplier, careful tuning and drying, and an independent hands-on confirms the stringing and scratching caveats.
Prusa's new Prusament PLA ColorMix bundle uses inkjet-style halftoning across five translucent CMYW+black spools to yield up to 45 printable shades on multi-material Prusa printers.
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.
Prusa Research's alpha11 build tears up PrusaSlicer's decade-old codebase for multi-bed projects, a Lua plugin system, and a fully offline mode built for firewalled shops — but SLA slicing and third-party profiles aren't in yet.
Prusa Research dropped a ground-up alpha rewrite of PrusaSlicer on Sept 1 — new UI, unlimited multi-printer beds, YAML profiles, and a sandboxed Lua plugin system — but it's Prusa-only and not production-ready yet.
A blowtorch test of a dozen filaments found ABS, ASA, and foam TPU burn readily with sooty yellow flames, while regular TPU and PETG strongly resist ignition even under direct flame.
Prusa delays INDX conversion kits for the CORE One/+ to mid-August after Bondtech admitted its 'hardened' nozzles are nitrocarburized ordinary steel (~30-32 HRC vs the promised 55-60) that 100 g of abrasive filament wears through — Prusa offers refunds and free hardware while Bondtech quietly renamed the product and has no compensation plan.
