1. Layer height: it stands for the height of single layer. With smaller layer height, you will get higher print quality but longer print time; with bigger layer height, you will get shorter print time but lower print quality. Choose to print with 0.2 mm layer height to guarantee print time and print quality. 2. Wall thickness: it is usually the common multiple of the nozzle diameter, ex 0.4mm, 0.6mm, 0.8mm and 1.0mm. Thicker the wall, stronger the print. If you want to reduce the print time, consider printing with a thinner wall. 3. Top and bottom thickness: set them to be 0.6mm 1.00 mm in general. We recommend that the top and bottom thickness to be the same as wall thickness and be the common multiple of the layer height. 4. Infill: Less infill will save you time and material, recommend to use 20%
infill. 5. Print speed: usually range from 40mm/s to 80mm/s, higher speed, short print time and lower printer quality. 6. Print temperature: set the temperature according to the material you are using. 180C - 210C for PLA, 210C - 240C for ABS. set the nozzle at an appropriate temperature will make your print looks better. 7. Heated bed temperature: set the temperature of the heated bed to be 50C - 80C so that the print will stick to the print bed better. 8. Support: inspect your model, see if there is anywhere that is not touching the build plate, if so, add support to support your print. If there is anything hanging internally, add support from the model to get a successful print. 9. Filament diameter: typical 3D printer filament has two sizes, 1.75mm and 3.0mm in diameter. If you are using 3.0mm diameter filament, choose 2.85mm or 3mm. 10. Retraction: retract setting greatly affect your print quality. Insufficient retract speed and retract distance would cause stringing on the surface of your print. If they are too high, the nozzle tends to stay near the surface of the print for a long time, which will also lower the print quality. We recommend and retract distance of 6mm and retract speed of 80mm/s. Shenzhen Bigtree Technology Co.,Ltd 27 The information above is for reference only.
