Original Prusa CW1S, curing and washing machine for SL1S

Description

The Original Prusa CW1S curing and washing machine is a post-processing station for objects printed with SLA technology. It takes over the two most important tasks that follow every resin print, so you can concentrate on your designs instead of the cleanup. Place the printed object in the machine, follow the washing and UV exposure instructions, and collect a finished part.

It is sold as a separate accessory for the Original Prusa SL1S 3D printer. Resin parts need to be washed more than once to remove the resin left on the surface, and they must then be exposed to UV light so that the liquid material cures fully. This machine covers both stages in a single, consistent workflow.

Key features

Two processes in one machine: washing to remove leftover resin and UV exposure to cure the part
Simple operation: insert the printed object, follow the washing and UV exposure instructions and take out the final part
Designed for SLA prints: made to follow the Original Prusa SL1S printer as a separate accessory
Repeatable results: every part goes through the same post-processing routine

Typical uses

Schools and universities that run resin printers in labs and classrooms and need a tidy post-processing routine
Makers, design studios and small workshops that print detailed SLA parts
Any workflow where printed objects must be cleaned of resin and fully cured before use or handling

Good to know

Post-processing time depends on the part, and once the washing and curing cycle is complete the object is ready in its final form. The machine is intended for objects printed with SLA technology and is not meant for FDM prints.

Frequently asked questions

What does this machine do?

It washes SLA-printed objects to remove leftover resin and then exposes them to UV light so that the resin cures completely.

Is it included with the Original Prusa SL1S printer?

No. It is a separate accessory for the Original Prusa SL1S 3D printer and is purchased on its own.

Why do resin prints need washing and curing?

After printing, an SLA object should be washed several times to remove the remaining resin and exposed to UV light so that the liquid material hardens fully.

Can I use it for FDM prints?

No. It is designed for objects printed with SLA technology.
