Printing tips
- Runs 10-15 C hotter than plain PLA; too cold gives weak layer bonding.
- Tougher but less stiff than standard PLA, so expect a little more flex in thin walls.
- Same bed and cooling settings as PLA otherwise.

Questions about PLA+ (Tough PLA)
What temperature should I print PLA+ (Tough PLA) at?
Nozzle 205–230 °C and bed 50–65 °C are the usual range. Start in the middle and tune with a temperature tower; no enclosure is needed.
How many metres of PLA+ (Tough PLA) are in a 1 kg spool?
About 335 m at 1.75 mm (density 1.24 g/cm³). One metre weighs 2.98 g.
Does PLA+ (Tough PLA) need drying?
Rarely for fresh spools. PLA+ (Tough PLA) absorbs moisture slowly; dry at 50 °C for 6 hours if it has been open for months or prints with unexpected stringing.
How much does PLA+ (Tough PLA) shrink?
About 0.3% linear. To compensate, scale X and Y by 100.30% in the slicer, or measure a test print and use the shrinkage calculator.
