The Cure/Wash Station (CW1 or CW1S) is used to wash, dry, and cure your resin prints, all in one compact package. While your IPA tank is present, the CW1/S will automatically detect it and allow washing. The tank can stir the IPA thanks to the magnetic propeller. A system of fans, UV LEDs, and a rotational platform will dry and cure your prints, all in one process.

Operating the CW1/S

To use the CW1/S menu, simply turn the knob left and right to scroll through the options, and press the knob to select the desired function.

The CW1/S will not work if the lid is open.

To start washing simply place your gastro-pan (tank) with IPA and the 3D-printed magnetic impeller on the guiding rails, mount your build-plate to the lid, and start the washing process from the top of the LCD menu.

The option to start drying/curing will only appear once you remove the tank from the guiding rails. When the basket is off of the rails, the option Start drying/curing will be shown on the top of the main screen.

The preheat option allows you to heat up the resin up to 40º C before Drying/Curing the model. Heating up the model before Drying/Curing will make the support easier to remove.

You can change the amount of washing, drying, and curing time from the LCD menu (See menu hierarchy below) depending on your preferences.

If you feel like an object was not dried or cured enough, you can run these processes individually. Please go to Settings-> Advanced settings-> Run mode, and you will see the options for just Drying, just Curing, or Drying + Curing. When you return to the main menu, the option you selected will be shown as Start Drying / Start Curing on top.

You can change the washing time by either rotating the knob during the process or by selecting a Run-time option before the print.

F.A.Q. - Frequently Asked Questions

Q: Is it necessary to dry a freshly washed object before putting it in the CW1/S?
A: No, a few drops of IPA are perfectly fine and they will evaporate quickly. However, leftover IPA combined with liquid resin may create white stains on dried/cured objects. See Chapter 9.2 Cured prints have white residue on the surface.

Q: How often do I need to replace the IPA in the container?
A: This depends on the frequency of washing, but from our experience, the IPA loses its washing properties after around 2 months of frequent use

Q: Can I wash an object multiple times?
A: Yes, but the total time should not exceed 10 minutes. Tiny cracks may appear on objects that were washed for too long (even after 24 hours).

Q: Why does the CW1/S use an IPA bath with a propeller instead of ultrasonic washing?
A: Our method has the same efficiency as ultrasonic washing and it’s less aggressive when washing small objects or objects with tiny details

Q: Can I cure an object multiple times?
A: Yes, extended exposure to UV light is not a problem
