Prof. Lab Resin Water Washable Skin

Water-washable resin Prof. Lab Resin Water Washable Skin is specially developed for SLA/LCD 3D printers (405 nm) and users who want maximum print quality combined with comfortable cleaning without IPA. Thanks to its white, opaque color, it is great for prototypes, figurines, architectural models, and parts intended for painting.

Main advantages

• Water washable – after printing, simply rinse the parts in water, no need to use isopropyl alcohol.
• High detail resolution – sharp edges, fine structures, and minimal loss of detail even for small models.
• Matte white, opaque surface – ideal for visual inspection of details, painting, and other surface finishes.
• Lower odor compared to classic resins – more comfortable work in the workshop or home office (however, always use ventilation).
• Good strength and stiffness – suitable for functional prototypes, models, figurines, and presentation parts.
• Optimized for standard LCD/UV printers 405 nm – compatible with most desktop resin printers.

Recommended use

• Modeling and figurines – miniatures, busts, board game figurines, collectible models.
• Prototypes and design – presentation models, product designs, covers, small components.
• Architectural and technical models – buildings, building details, technical elements, concepts.
• Parts for painting and coloring – the white base highlights colors, suitable for airbrush and classic paints.

Printing recommendations

Specific values may vary depending on the printer, layer height, and conditions – always perform a trial calibration print.

• UV wavelength: 405 nm
• Recommended layer height: 0,025–0,05 mm for detailed models, 0,05–0,1 mm for larger parts
• Exposure time (classic monochrome display):
  • normal layers: approximately 2–3,5 s
  • bottom layers: 20–35 s (4–8 layers)
• Ambient temperature: 20–28 °C for stable results

Post-processing

1. Rinse after printing – rinse the freshly printed model in clean water (preferably in a dedicated container or resin model washer).
2. Water change – change the water regularly, do not leave settled resin in it for long periods.
3. Drying and final cleaning – after the rough rinse, you can perform a second short rinse in clean water for a better surface.
4. Airing – let the model drip and dry.
5. Post-curing – cure in a UV chamber or under UV light depending on the size of the model (usually 5–15 minutes).

Do not pour used water down the drain. Leave it in the light so that the dispersed resin cures, and then dispose of it according to local legislation as waste containing plastic.

Safety

• Always use protective gloves and ideally glasses.
• Work in a well-ventilated area and prevent contact with skin and eyes.
• Store in a dark place at room temperature, out of reach of children and pets.
