0.6 vs 0.4 mm Nozzle: What Changes, in Numbers
Line width, layer height ceiling, flow demand, print time and detail for a 0.6 mm nozzle against a 0.4 mm, from Prusa, Bambu Lab and OrcaSlicer docs.
How to get a setting, a price or a material choice right, with the numbers worked through.


Line width, layer height ceiling, flow demand, print time and detail for a 0.6 mm nozzle against a 0.4 mm, from Prusa, Bambu Lab and OrcaSlicer docs.

Published clearances for sliding, loose and press fits on FDM printers, why holes print small and first layers flare, and how to find your own number.

What a 3D printer costs to run in the UK at the Ofgem price cap from 1 October 2026, using maker-published average power, not the spec sheet maximum.

Bambu Lab A1 and A1 mini specs side by side from the manufacturer's pages: build volume, bed temperature, footprint, power and price, and who each one suits.

Clean plate, right plate type, bed temperature by material from maker data sheets, nozzle height and first layer speed, per Prusa and Bambu Lab.

Meters per kilogram for 11 materials in 1.75 and 2.85 mm, worked out from data sheet densities, plus how to tell whether a part-used spool will finish a print.

Price a 3D print with one formula: material, energy, machine wear and your time, corrected for failed prints, then marked up. Full worked example.

Drying temperatures and times per material from maker data sheets, why 10 degrees too hot ruins PLA, and dryer vs oven vs printer bed with sources.

The causes of stringing ranked, with the retraction lengths, temperature steps and drying figures that Prusa, Bambu Lab, OrcaSlicer and Klipper publish.

What Prusa, OrcaSlicer and Protolabs Network say about infill versus walls, the little test data there is, and where the plastic is best spent.

What Prusa, Bambu Lab and OrcaSlicer each state as the layer height range for a nozzle, why they differ, and how volumetric flow sets the real ceiling.

Heat deflection at stated load, UV behavior as the makers describe it, and enclosure needs for PETG, ABS and ASA parts that have to live outside.

PLA vs PETG compared on maker data sheets: temperatures, drying, density and heat deflection at a stated load. Plain advice on which to use where.

What pressure advance does, how to tune it with Klipper's tuning tower or OrcaSlicer's three tests, and the value ranges the firmware docs publish.
