Slicing Settings Quick Reference - PrusaSlicer

Recommended Settings by Use Case

Use Case	Layer Height	Infill	Supports	Notes
Quick test / prototype	0.30 mm	10%	As needed	“Draft” - fastest, roughest
Standard project	0.20 mm	15-20%	As needed	Best all-around starting point
Functional part	0.20 mm	30-40%	As needed	Use for parts under stress
Fine detail / display	0.15 mm	15%	As needed	Smoother surface; slower
Solid reference part	0.20 mm	40-50%	Rarely	Rarely needed; long print

Filament Temperature Settings

Filament	Nozzle Temp	Bed Temp	Notes
PLA	200-215C	50-60C	Easiest to print; default choice
PETG	230-250C	70-85C	Use glue stick on PEI bed
TPU	220-240C	30-60C	Print at 20-30 mm/s max; direct drive only
ABS	230-250C	90-110C	Requires enclosure; more fumes

Always check the temperature range on your filament spool - it may vary by brand.

Support Settings Guide

Overhang Angle	Supports Needed?	Recommended Setting
< 45	No	None
45-60	Maybe	Preview first; add if sagging
> 60	Yes	Support on build plate only
Bridge < 20 mm	No	Bridges usually fine
Bridge > 20 mm	Maybe	Preview; consider reorienting

Common Print Problems & Quick Fixes

Problem	Likely Cause	Fix
Print lifts off bed	Poor adhesion / warping	Add brim; use glue stick; level bed
Stringing between parts	Temperature too high / retraction	Lower temp 5C; check retraction settings
Layer lines very visible	Layer height too thick	Use 0.15mm or 0.20mm
Print takes too long	Layer height too thin / infill too high	Use 0.30mm draft; reduce infill
Holes too small	FDM tolerance - always undersized	Add 0.2-0.3mm to hole diameter
Part broke at layer boundary	Weak axis perpendicular to layers	Reorient so load is parallel to layers
First layer not sticking	Bed not level	Run bed leveling routine
Spaghetti / print failure	No supports on overhang	Add supports or reorient

G-code Export Checklist

Before exporting, confirm:

Correct printer profile selected
Correct filament profile selected
Layer height appropriate for use case
Infill percentage set
Supports enabled if needed
Layer preview reviewed (no floating parts, supports where needed)
Print time and filament weight noted for your records
