Product Description

Prusament Resin Model Classic Red is a premium modeling resin from Prusa Research, designed for maximum comfort and safe 3D printing using the MSLA/LCD method. It is based on the proven Tough series, but its formulation is optimized for modelers, figurines, and detailed prototypes – combining high stiffness, minimal shrinkage, excellent bed adhesion, and low odor.

The Classic Red shade is a rich, opaque red color that excellently highlights fine details and is perfect for figurines, models, decorations, branding, and presentation parts.

Main Advantages

• High resolution and sharp details – ideal for miniatures, figurines, jewelry, design, and technical prototypes.
• Short exposure times – fast printing, especially in combination with the Original Prusa SL1S SPEED printer.
• Perfect bed adhesion – reduces the risk of failed prints and model detachment.
• Low shrinkage and resistance to deformation – dimensionally accurate parts suitable even for functional prototypes and precise models.
• Low odor and lower health risk – a special formula minimizes unpleasant fumes; cured parts are non-cytotoxic and do not irritate the skin.
• BPA-free, TPO-free, and acryloylmorpholine-free – a gentler formulation compared to many common resins.
• Universal use – hobby, modeling, educational purposes, art & design, industrial prototypes, dental and technical models.

Typical Uses

• Modeling and figurines – tabletop games, collectible figurines, model railways, architectural models.
• Art & design – jewelry, statues, design elements, decorative objects.
• Prototyping – precise technical parts, covers, small mechanical components, presentation models.
• Education – anatomical, technical, or scientific models for schools, universities, and clubs.
• Molds and castings – printing a master model for a silicone mold or directly for casting molds (e.g., silicone, low-temperature materials).

Printing Properties

• Compatibility:
  • Optimized for Original Prusa SL1S SPEED, but fully usable with other MSLA/LCD resin printers (405 nm).
• Fast printing:
  • Thanks to low viscosity and an optimized formulation, it allows for very short exposure times (specific values according to the profile in PrusaSlicer for your printer).
• Stable results:
  • Low shrinkage and good dimensional stability – suitable for parts where precise dimensions matter.
• Surface and processing:
  • Smooth surface, sands well, and can be further processed (both wet and dry sanding can be used, but working with appropriate protection is recommended).

Recommendations for Working with Resin

Always follow safety principles when working with any UV resin.

• Protective equipment: use gloves, protective glasses and good room ventilation are also recommended.
• Skin contact: avoid contact with liquid resin; in case of contact, wash immediately with soap and water.
• Mixing: shake the bottle thoroughly before printing to ensure the pigment is evenly dispersed.
• Washing medium: use the recommended medium (IPA or special resin cleaner) for degreasing prints and follow the recommended washing time.
• Curing: after printing and washing models, always perform thorough UV curing according to the manufacturer's recommendations.
• Waste disposal: dispose of liquid resin residues, contaminated paper towels, gloves, and prints as hazardous waste according to local legislation. Do not pour unprocessed resin down the drain.
