STEP and G-code files are read on our server; their dimensions and price arrive within seconds.
Dimensions, size and rotation
Arrows on the model show its width, depth and height in mm. You can change the size as a percentage or enter the X, Y and Z dimensions in mm (proportionally or axis by axis) and rotate the model in 90° steps; the price updates for the new size.
The print price on the same page
As soon as you upload your model, it is sliced with our real print settings and the print weight, print time and price appear right here. You can choose material, colour, infill and quantity and send your order directly; before printing, our advisor checks your file and asks for your approval.
