Thomas Sanladerer's review, as summarized by Hackaday, finds that the Prusa CORE One INDX's mandatory calibration is built around Prusament, that manual calibration results are not saved and that the hardware blocks the camera, while a Prusa XL just worked.
Read the story →Prusa now sells the same raw pellets it uses to make Prusament filament, shipped pre-dried in batches up to 14 kg, for large-format pellet printing and small-scale polymer R&D. The 4 kg PLA bag lists at $44.99.
A dead Prusa i3, the open-source Allstruder syringe extruder and a Duet 3 board add up to a hobby-bench embedded printer: cream cheese tested the mechanics, epoxy failed in hair gel, and Sylgard 184 silicone finally printed.
Prusa Research is selling a tool-free 400 C HT Hotend upgrade for the CORE One and CORE One L families, plus a CORE One L+ that ships with the hotend and filtration already fitted.
Prusa's September 25 firmware releases refine XL+ chamber-temperature estimation and revert a bed-lowering regression, while the CORE One INDX gains a standalone gantry-squareness check and a homing reliability fix.
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.
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.
