Design Rules

Our printer: FORMBYTES


Material Filament Material PLA Temperature 190~220 Filament Colors Yellow, Green, Orange, Gray Filament diameter 1.75mm

All in One Test Sample

• About
• Check Lists

Size: the object is 4 x 50 x 50 mm (baseplate)	Measure with a caliper
Hole size: 3 holes (3/4/5mm)	measure with a caliper/drill
Nut size: M4 nut should fit perfectly	insert an M4 nut; it should need a little pressure
Fine details: pyramid, cone, all numbers	check if all things look nice and smooth
Rounded print: wave, half sphere	check if all things look nice and smooth (not every printer handles round things similar, e.g, it will be split in polygons)
Minimum distance between walls: 0.1/0.2/0.3/0.4/0.5 mm	depending on your nozzle size and slicer settings you will get different results
Overhang: 25°/30°/35°/40°/45°	depending on printed material/cooling, these will not be as seen on the rendering provided
Flatness: all flat areas	these should be flat with no gaps

Test Probes

1. Technical Performance
• Heatbed temperature ~200
• Print speed ~50mm/s
• Cooling pan ~good
• Strain relief (wires) ~no wire pinch points
• Thermocouples well attached to Hot end ~fair
• Thermocouple well attached to Heated Bed ~good
2. Expression Issues
• Flateness ~bad
• Axis ~mirrored (setting required when texts are supposed to be printed)
• Text, numbers ~hard to read
• Fine details: Pyramid, cone ~fair (tip point is clumsy)
• Rounded print: Wave, half sphere ~good
• Bridging:2/3/4/5/6/7/8/9mm ~good
• Overhangs: 25/30/35/40/45 ~good
3. Calibrating
• Object Size (4x50x50mm) ~(_/50x50mm)
• Hole size (3.0/4.0/5.0mm) ~ (3.1/4.7/4.9mmm)
• Nut size ~M4 fits
