Every FilamentFeed story on PrusaSlicer — news, reviews, and analysis, newest first.
Kubuz's free browser tool 3dSynth generates G-code directly for vase-mode, spiral and generative FDM prints, bypassing the slicer entirely while still exporting STL when a traditional slicer is needed.
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.
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 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.
Prusa and E3D manufacturer data on how nozzle diameter caps layer height and flow rate, with per-size guidance for detail work, general printing, and speed.
Cantilever and annular snap fits are deceptively simple mechanisms that FDM printers struggle to reproduce reliably. Here is the geometry, deflection math, clearance strategy, and material selection logic to get them right on the first print.
The slicer landscape in 2026 has fragmented along clear lines: ecosystem loyalty, calibration depth, and hardware compatibility each favor a different tool, and the right answer depends almost entirely on what you are printing on.
Multi-color printing without a filament changer is entirely achievable using M600 and pause-at-layer commands. The slicer implementations differ in important ways, and getting the G-code sequencing wrong produces failed swaps, ooze blobs, or color bleed that contaminates the swap layer.
STL has been the default 3D printing format for 35 years. The 3MF format does everything STL does and adds color, material, orientation, and multi-part support — here's why the transition is accelerating.
Adaptive or variable layer height lets slicers use thin layers where they matter and thick layers where they don't. The result is better surface quality at nearly the same print time.
All three major slicers can get plastic on a print bed. Where they diverge is in workflow philosophy, calibration tooling, and how tightly they're coupled to their hardware ecosystems.
