Working slicer settings for your exact printer and filament — in under a minute. Pick your printer, nozzle, material, and what you're actually trying to print. 3D Print Assistant turns that into an optimised slicer profile — layer height, speeds, temperatures, infill, supports, and more — organised to match the tab structure of Bambu Studio, OrcaSlicer, or PrusaSlicer. SAVE YOUR GEAR ONCE Your printer, your filament, your nozzle are the answers that never change from print to print. Save them once as a gear, and every new print starts already filled in. Tap a gear and you skip straight to the first question it can't answer for you. EXPORT STRAIGHT TO YOUR SLICER For most supported printers, export a real profile file and import it — no retyping. Where your slicer genuinely ships no profile for a machine, the app says so up front and hands you the settings as text instead. TWO MODES — YOUR CHOICE Simple gives you just the essentials. Switch to Advanced for the full picture, with every setting explained so you know what it does and why it's set that way. WHAT'S INCLUDED • My Gear — save your printer, filament, and nozzle once, and every new print starts pre-filled • 80+ printers across 14 brands — with optional alerts when more are ready • 19 filament profiles — PLA, PETG, ABS, ASA, TPU, PA, PC, CF blends, PLA Metal, and more • 9 nozzle types with compatibility checking • Native profile export when your slicer publishes a matching machine preset — with a clear text fallback everywhere else • Workshop profile saving plus clear backup and restore • A pre-print checklist tailored to your exact material and config • Full Danish localisation, switching with your device language • Works offline after install — no account or subscription required BUILT BY SOMEONE WHO USES IT 3D Print Assistant started because I couldn't find a structured way to pick the right settings for a new material or printer. So I built it. The recommendations draw on community knowledge, hands-on experience, and manufacturer defaults — a starting point you can trust, then tune to your setup. Every setting shows what it does and why it was chosen, so you stay in control. Everything in the app is free. If it saves you a failed print or two, there's an optional tip jar — nothing is locked behind it. Works with Bambu Studio, OrcaSlicer, and PrusaSlicer.
