Settings for the highest level of accuracy

Recommended Posts

If you don't care how pretty the parts are you can print them quite fast.

The best method whether you print fast or slow is to print it once and then measure all the errors and then adjust your CAD model by those amounts. For example all your vertical holes will be around .5mm too small in diameter but your outside surfaces will be only shrunk by around .3%. Horizontal holes will be almost perfect. Bottom layers might exhibit swelling inwards or outwards depending on heat bed temperature and height from heated bed and fan speed for a given layer.

All of these can be compensated for in CAD such that you get a perfect part. Usually if a part has 50 dimensions only 5 or so are critical for fitting with other parts.

However if you change your print speed, bed temp, fan speeds, nozzle temp the part might change a little bit. Even if you change printers.

This may sound like a pain in the neck but usually I only have to print a few layers to get a measurement as the Z dimensions are always the most accurate.
