The Phrozen Wash Mega S is a professional washing station designed to clean photopolymer resin-printed parts efficiently and without hassle. With a 25-litre capacity and a dual-vortex system with automatic direction reversal, it removes uncured resin residue from large parts or multiple parts simultaneously, with no manual scrubbing required.

What it's used for
The Wash Mega S is designed for professionals and workshops with medium-to-high volume production, as well as advanced hobbyists who print large or serial parts. It removes uncured liquid resin residue from the surface and cavities of the part before the UV curing process.
- Cleaning of large-format parts printed with standard, ABS-Like, 8K or engineering resins.
- Simultaneous washing of full build plates with miniatures or small parts.
- Part preparation before curing with the Phrozen Cure Mega S.
- Workflows with high-resolution resins that require complete removal before curing.
- Production workshops that need to drain and reuse solvent in a controlled manner.
- Use with 99.9% isopropyl alcohol as the primary solvent.
How to use it
- Place the station on a stable surface in a ventilated area. Put on nitrile gloves before handling parts with uncured resin.
- Fill the tank to the indicated level with 99.9% isopropyl alcohol. Do not exceed the 25 L capacity.
- Carefully remove the printed part from the build plate and place it in the inner basket of the station.
- Close the lid, select the speed (high 300 rpm or low 275 rpm) and set the timer between 1 and 30 minutes depending on the size and complexity of the part.
- Start the cycle. The dual vortex will automatically reverse direction every minute to ensure the solvent reaches all cavities.
- When finished, remove the basket and let the part drip for a few seconds over the tank.
- Transfer the clean part to the UV Cure Lamp to complete the post-processing workflow.
- When the solvent is saturated with resin, drain it using the side valve. Dispose of the residual liquid in accordance with local chemical waste regulations.
Safety warning: Isopropyl alcohol is flammable. Keep the station away from flames, sparks or heat sources during use and draining. Always work in a ventilated space. The residual liquid contains uncured resin and must be treated as hazardous waste; do not pour it down the drain. Wear nitrile gloves and safety goggles throughout the entire operation.
Usage tips
Wash time by part type
For simple or thin-walled parts, 3–5 minutes is usually sufficient. Large-volume parts with complex internal geometry or printed with highly viscous resins may require between 10 and 20 minutes. Avoid excessive wash times: prolonged exposure to alcohol can soften the surface of very thin parts.
Keep your solvent in good condition
Solvent saturated with resin reduces washing effectiveness and can leave deposits on the part. Expose used solvent to natural or artificial UV light to polymerise suspended resin residue, filter it and reuse it a couple of times before discarding. The side valve makes this process easier without needing to tilt the machine.
Use low speed for delicate parts
The 275 rpm speed is gentler and reduces the risk of fine details or lightly supported areas being damaged by agitation. Reserve 300 rpm for robust parts or those with deep cavities where greater solvent penetration is needed.
Frequently asked questions
What solvent should I use in this washing station?
The most common and recommended solvent is 99.9% isopropyl alcohol. Some resin manufacturers also allow the use of soapy water depending on the formulation, but isopropyl alcohol remains the standard for most photopolymer resins. Always check the TECHNICAL DATA SHEET for your resin before choosing a solvent.
How long does it take to wash a large part?
The Phrozen Wash Mega S has an adjustable timer from 1 to 30 minutes. For large-format parts or those with complex geometry, a cycle of 10 to 20 minutes is usually sufficient. The dual-vortex system with automatic reversal reduces the time needed compared to static or manual washing.
Can I wash multiple parts at the same time?
Yes. The internal capacity of 33 x 19 x 30 cm allows multiple small parts to be placed simultaneously. Make sure they are not stacked in a way that they touch each other or leave areas without contact with the solvent, as this can leave uncured resin residue.
Which printers is this station compatible with?
The Wash Mega S is compatible with build plates up to 38.1 cm (15 inches), making it suitable for the Phrozen Sonic Mega 8K S and other large-format models. It also accepts plates of 34.5 cm, 33.8 cm and 32.5 cm, covering most mid-to-high-end resin printers on the market.
How do I drain the used solvent?
The Wash Mega S features a side drain valve that allows you to empty the tank in a controlled manner without needing to tilt or lift the machine. Connect a suitable hose or container to the valve and open it. Manage the residual liquid as hazardous waste in accordance with your local regulations.
Do I need to cure the part after washing?
Yes, washing removes uncured resin from the surface, but it does not polymerise the part. After washing it is essential to expose the part to UV light using a UV Cure Lamp so that it achieves its final mechanical properties. Without this step, the part remains soft and brittle.
What safety precautions should I take during use?
Always work with nitrile gloves and in a ventilated space. Isopropyl alcohol is flammable; keep the station away from flames and heat sources. Uncured resin is irritating and potentially sensitising, so avoid direct skin contact. Residual solvent must be managed as hazardous waste.
What is the difference between high and low speed?
High speed (300 rpm) generates more intense agitation, ideal for robust parts or those with deep cavities where the solvent needs greater penetration. Low speed (275 rpm) is gentler and recommended for parts with fine details, thin supports or fragile geometries that could be damaged by excessive agitation.
