Prof. Lab Resin Water Washable - Grey / Gray

Prof. Lab Resin Water Washable Grey / Gray

Water-washable resin Prof. Lab Resin Water Washable Grey 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, figurines, architectural models and parts intended for painting.

Main advantages

• Water-washable – after printing, simply rinse the parts in water, there is no need to use isopropyl alcohol.
• 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 (still always use ventilation).
• Good strength and rigidity – suitable for functional prototypes, models, figurines and presentation parts.
• Optimized for common LCD/UV printers 405 nm – compatible with most desktop resin printers.

Recommended use

• Model making and figurines – miniatures, busts, board game figurines, collectible models.
• Prototypes and design – presentation models, product designs, covers, small parts.
• Architectural and technical models – buildings, construction details, technical elements, concepts.
• Parts for painting and coloring – white base enhances 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 resin wash station).
2. Water replacement – change the water regularly, do not leave resin settled in it for a long time.
3. Drying and secondary rinse – after the initial rinse you can do a second short rinse in clean water for a better surface.
4. Draining – let the model drip off and dry.
5. Post-curing – cure in a UV chamber or under UV light according to model size (usually 5–15 minutes).

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

Safety

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

Technical parameters

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