Layer height for a 0.2 mm nozzle: 0.04 to 0.16 mm, 0.10 mm first layer

A 0.2 mm nozzle prints layers from 0.04 to 0.16 mm (20% to 80% of its diameter), or 0.04 to 0.14 mm on Bambu Lab printers. Start at 0.10 mm with a 0.10 mm first layer. Drop to 0.08 or 0.06 mm for fine detail such as tabletop miniatures, at the cost of more layers on a nozzle that is already slow: Bambu Studio caps its PLA (polylactic acid) flow at about a tenth of a 0.4 mm nozzle’s.

What layer height should you use with a 0.2 mm nozzle?

Use 0.10 mm, the default Bambu Studio picks for every Bambu Lab printer with a 0.2 mm nozzle, and stay between 0.04 and 0.16 mm. That range is 20% to 80% of the nozzle in OrcaSlicer’s documentation, and UltiMaker Cura warns past either end. On Bambu Lab printers, whose profiles stop at 70%, print 0.04 to 0.14 mm.

Slicer or printer profile	Min	Max	Where the limit comes from
OrcaSlicer wiki	0.04 mm	0.16 mm	20% to 80% of the nozzle
OrcaSlicer 2.4, generic Klipper printer, 0.2 mm nozzle	0.04 mm	0.16 mm	Layer height limits in the printer profile
UltiMaker Cura 5.13	0.04 mm	0.16 mm	Warns under 0.04 mm and above 80% of the nozzle
Bambu Studio, every Bambu Lab printer with a 0.2 mm nozzle	0.04 mm	0.14 mm	Layer height limits, 20% to 70%
PrusaSlicer 2.9, Original Prusa MK4S and Prusa CORE One, 0.25 mm nozzle	0.05 mm	0.15 mm	Layer height limits in the printer profile

Type 0.16 mm into a Bambu Studio 0.2 mm nozzle profile and it warns that the layer height “exceeds the limit in Printer Settings -> Extruder -> Layer height limits”, then offers to adjust it to 0.14 mm. The layer height calculator gives the range for any nozzle.

Layer height presets for a 0.2 mm nozzle in each slicer

Slicer, printer profiles	Layer presets	Default	Line width
Bambu Studio, X1, X1 Carbon, X1E, P1S, P1P, A1, A1 mini	0.06, 0.08, 0.10, 0.12, 0.14 mm	0.10 mm	0.22 mm
Bambu Studio, H2D, H2D Pro, H2S, H2C, P2S, X2D, A2L	0.08, 0.10, 0.12 mm	0.10 mm	0.22 mm
OrcaSlicer, Voron profiles	0.06, 0.08, 0.10, 0.12, 0.14 mm	0.10 mm	0.22 mm
OrcaSlicer, generic Klipper printer	0.08, 0.12, 0.15, 0.16 mm	none	0.20 mm outer wall, 0.22 mm inner walls
UltiMaker Cura, Creality printers	0.08 mm (Ultra Quality), 0.12 mm (Super Quality)	none	0.20 mm
PrusaSlicer, MK4S and CORE One, 0.25 mm nozzle	0.05, 0.07, 0.12, 0.15 mm	0.12 mm	0.25 to 0.27 mm

• Pick a 0.2 mm printer profile first. Bambu Studio shows its 0.2 mm presets only when one is selected, such as “Bambu Lab A1 mini 0.2 nozzle”.
• PrusaSlicer 2.9.6 has no 0.2 mm profile for the MK4S or CORE One. Its smallest nozzle for either is 0.25 mm, with “0.12mm STRUCTURAL” as the default preset.

Bambu Studio’s 0.22 mm lines are 110% of the nozzle; the line width calculator turns them into wall thickness.

What first layer height should you use with a 0.2 mm nozzle?

Use 0.10 mm, half the nozzle diameter. Every Bambu Studio preset for a 0.2 mm nozzle prints its first layer at 0.10 mm, whatever the layer height. OrcaSlicer’s wiki lists 0.12 mm and recommends at most 65% of the nozzle (0.13 mm), so a 0.2 mm nozzle’s first layer belongs between 0.10 and 0.13 mm.

Slicer, profile	First layer height
Bambu Studio, every 0.2 mm nozzle preset	0.10 mm, with 0.25 mm lines
OrcaSlicer, Voron 0.2 mm nozzle profiles	0.10 mm, with 0.25 mm lines
OrcaSlicer wiki, 0.2 mm nozzle	0.12 mm, and 0.13 mm (65%) at most
UltiMaker Cura, Creality 0.2 mm profiles	0.12 mm. Cura warns under 0.10 mm and above 0.16 mm
OrcaSlicer, generic Klipper presets	0.20 mm, the same as on a 0.4 mm nozzle
PrusaSlicer, MK4S and CORE One 0.25 mm presets	0.20 mm, with 0.32 mm lines

A thicker first layer improves bed adhesion and “compensates for build surface imperfections”, in the words of OrcaSlicer’s wiki. PrusaSlicer’s tooltip says the same about build plates that are not perfect. By that reasoning, a 0.10 mm first layer leaves the least margin for an uneven plate. If yours won’t stick or shows gaps, raise it to 0.12 mm and keep it within OrcaSlicer’s 0.13 mm cap.

Don’t carry a 0.20 mm first layer over from another profile. On a 0.2 mm nozzle it equals the nozzle diameter, past OrcaSlicer’s 65% cap and Cura’s 80% warning. Prusa’s knowledge base says Original Prusa profiles always use 0.20 mm, and OrcaSlicer’s generic Klipper presets keep the value they use on a 0.4 mm nozzle. Lower it to 0.10 or 0.12 mm.

Where to set it

Slicer	Layer height	First layer height
Bambu Studio	Process > Quality > Layer height	Process > Quality > Initial layer height
OrcaSlicer	Process > Quality > Layer height	Process > Quality > First layer height
PrusaSlicer	Print Settings > Layers and perimeters > Layer height	Print Settings > Layers and perimeters > First layer height
UltiMaker Cura	Print settings > Quality > Layer Height	Print settings > Quality > Initial Layer Height

After changing the first layer height, rerun your first layer calibration (Z offset), which Prusa’s knowledge base says the change will most likely require.

What layer height should you use for D&D minis?

Use 0.08 mm with a 0.2 mm nozzle. Bambu Lab’s wiki names tabletop miniatures as a very common use for this nozzle, and the company’s blog on printers for miniatures pairs it with 0.08 mm layers. Bambu Studio goes down to a 0.06 mm preset.

Layer height and nozzle sharpen different parts of a figure. Prusa’s knowledge base says layer height sets only the vertical resolution. The company’s nozzle article ties it to detail on slanted sides and organic shapes, where layer lines show most. The nozzle sets detail parallel to the bed, such as text on a top surface.

A smaller nozzle helps minis less than you might expect. Prusa Research’s test of a 0.25 mm nozzle found only a minor quality improvement on miniatures; the clear win was supports, which came off easily and left nearly invisible marks. Prusa’s knowledge base also advises against going below 0.10 mm in general: 0.07 and 0.05 mm layers add little quality for much longer prints.

Layer counts for a figure 30 mm tall (figure and base sizes in D&D miniature scale):

Layer height	Layers	Against 0.10 mm
0.06 mm	500	1.67 times
0.08 mm	375	1.25 times
0.10 mm	300	1
0.12 mm	250	0.83 times
0.14 mm	214	0.71 times

Print minis in the filaments Bambu Lab’s wiki lists for this nozzle: PLA, PETG (glycol-modified polyester), ABS (acrylonitrile butadiene styrene) and ASA (acrylonitrile styrene acrylate). It warns that carbon fiber, glass fiber, sparkle, galaxy and glow-in-the-dark filaments clog or wear the nozzle. Thin layer lines also bond less well, the wiki adds, so most 0.2 mm nozzle prints come out weaker than prints from a 0.4 or 0.6 mm nozzle.

How much longer does a 0.2 mm nozzle take to print?

More layers and a much lower flow cap both slow a 0.2 mm nozzle. At the 0.10 mm default, a 50 mm tall part is 50 ÷ 0.10 = 500 layers, against 250 at 0.20 mm. In Bambu Lab’s wiki, one model took 1 h 19 min at 0.08 mm and 36 min 14 s at 0.20 mm: 2.2 times as long for 2.5 times the layers.

Bambu Lab’s wiki calls the flow cap the biggest limit on this nozzle’s speed. Bambu Studio caps Bambu PLA Basic at 2 mm³/s on a 0.2 mm nozzle, against 21 mm³/s in its base profile. Generic PLA gets 1.6 mm³/s against 12 mm³/s. The wiki advises caution above 2 mm³/s because pushing more through can make the extruder skip, grind the filament or extrude inaccurately.

At 0.10 mm layers and 0.22 mm lines, 2 mm³/s allows 2 ÷ (0.10 × 0.22) = 91 mm/s. That cap sets the pace, well under the 150 mm/s inner wall speed in the X1 Carbon’s 0.10 mm preset. Bambu Lab adds that color changes and the start-up calibration also take longer on this nozzle.

To estimate a job, open the print time calculator and set Line width to 0.22 mm, Layer height for this print to 0.10 mm and Max volumetric speed to 2 mm³/s.
