Prof. Lab Resin Water Washable - Skin

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 and at the same time comfortable cleaning without IPA. Thanks to its white, opaque color it is great for prototypes, miniatures, architectural models and parts intended for painting.

Main benefits

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

Recommended applications

• Model making and miniatures – miniatures, busts, board game figures, collectible models.
• Prototypes and design – presentation models, product concepts, housings, small components.
• Architectural and technical models – buildings, construction details, technical elements, concepts.
• Parts for painting and coloring – the white base highlights colors, suitable for airbrush as well as classic paints.

Printing recommendations

Specific values may vary depending on the printer, layer height and conditions – always perform a test 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):
  • standard 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 a resin wash station).
2. Water replacement – change the water regularly, do not leave resin deposits in it for a long time.
3. Drying and second rinse – after the initial rinse you can perform a second short rinse in clean water for a better surface finish.
4. Air drying – let the model drain and dry.
5. Post-curing – cure in a UV chamber or under UV light according to 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 regulations as waste containing plastic.

Safety

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

Technical parameters

Note: Specific volume and exact printing profiles may vary depending on the production batch and the printer used – we recommend always checking the current manufacturer datasheet and performing a calibration test.
