What OrcaSlicer is

OrcaSlicer is a slicer derived from Bambu Studio, which grew out of PrusaSlicer. It supports printers from many makers, including ones Bambu Studio does not know. It has predefined profiles and calibration tests for flow, temperature or retraction. You will find the documentation on the project wiki.

OrcaSlicer in our calculator

We calculate the price and the lead time on the server with a program based on OrcaSlicer. After you upload a model it is genuinely prepared for printing, so we find out the grams of material, the print time and how many pieces fit on one bed. That is why the price is not an estimate from volume. We generate supports automatically and they are included in the price, as are minor mesh repairs.

How to send a model from OrcaSlicer

The simplest thing is to save the project as 3MF, which keeps the colours and dimensions. If you have only one colour, STL is enough too. For more colours, assign the colours to parts of the model and save the project. Upload a file up to 50 MB.

Do not send G-code. It is prepared for a different printer and we cannot use it.

The difference between your calculation and ours

If you have already printed something with OrcaSlicer, you know that calibration tests help you fine-tune flow, temperature and speed. We have that sorted out for our own printers. For you this means you can send a model no matter which printer you have, and it will be printed to our settings.

If you prepare a model yourself in OrcaSlicer, the time and material use may come out different from ours, because we print on different printers with our own profile. You choose the strength and the material in the calculator and the price is then recalculated accordingly.

Common questions

Is OrcaSlicer free?

Yes, it is free and open source.

Should I send a project from OrcaSlicer?

Yes, as 3MF. We accept it up to 50 MB, with colours assigned.

Why does the print time differ from what my OrcaSlicer shows?

We print on different printers with a different profile and speeds. What counts is the calculation in our calculator.
