Product Description

Prusament Resin Basic Black 1kg is the entry-level series of photosensitive resin from Prusa Polymers designed for everyday SLA/MSLA 3D printing. It offers easy printing, good detail, and low toxicity while maintaining a very favorable price. The Basic Black color finish creates matte black, visually clean prints, ideal for presentation models, miniatures, prototypes, and small design parts.

The resin is free of Bisphenol A (BPA), Acryloylmorpholine, TPO, and other highly toxic components, yet it maintains reliable printability and consistent properties. Thanks to its low viscosity, it flows well out of model cavities, reduces the risk of bubbles, and facilitates subsequent cleaning.

Main Advantages

• Affordable resin for everyday use
  A great choice for hobby and corporate rapid prototyping, test parts, and visual models.
• Easy printing with fine details
  The formulation is optimized for reliable printing without unnecessary tuning of exposure times, with good detail reproduction for miniatures, figures, and jewelry.
• Low viscosity and low odor
  The resin drips off the model better, shortening the drip time and facilitating washing in IPA/ethanol. Low odor contributes to more comfortable use in the workshop or home office (with proper ventilation).
• Lower toxicity and safer composition
  It does not contain Bisphenol A, Acryloylmorpholine, or TPO, which are components often associated with higher toxicity in common hobby resins. When properly cured, finished prints are not cytotoxic or skin irritants.
• Optimized for Original Prusa SL1S SPEED
  The resin is primarily tuned for the Original Prusa SL1S SPEED, where it allows for very short exposure times (e.g., as low as 3.2 s per layer at a height of 0.025 mm – per manufacturer's recommendation) and fast print series. It is also compatible with most MSLA/LCD printers with a wavelength of 405 nm.
• Ideal for visual parts
  Due to higher shrinkage and slightly lower adhesion to the platform (compared to the Prusament Model Resin series), this basic series is mainly suitable for visual models, not for precision dental or extremely dimensionally demanding production.

Recommended Use

Prusament Resin Basic Black 1kg is particularly suitable for:

• Figures and miniatures (tabletop games, collectible models, dioramas)
• Rapid visual prototypes of products and design elements
• Jewelry and small decorative parts to verify shape and appearance
• Presentation and educational models (architectural models, teaching aids)
• Hobby projects and parts where appearance and detail are important, not high mechanical load

Material Properties

• Material type: photosensitive acrylate resin for SLA/MSLA/LCD 3D printing
• Color finish: Basic Black (black)
• Viscosity: low – better flow from the model, faster work with parts
• Odor: low compared to common hobby resins
• Toxicity (liquid state): reduced, however protective equipment must be used
• Free of hazardous components: does not contain Bisphenol A (BPA), Acryloylmorpholine, TPO
• Shrinkage: higher than Prusament Model Resin – must be taken into account for very precise functional parts
• Adhesion to the bed: slightly lower than Model Resin – adjust first layer and peeling settings

Compatibility

The resin is intended for MSLA/LCD printers with a UV wavelength of 405 nm, including:

• Original Prusa SL1S SPEED (recommended settings in PrusaSlicer / manufacturer profiles)
• Other compatible MSLA/LCD printers of various brands (Anycubic, Elegoo, Creality, and others), with manual tuning of exposure times according to the specific device.

Safety and Handling

Although Prusament Resin Basic is designed as the least toxic hobby resin possible, it is still necessary to follow standard safety procedures for working with resins:

• Always use nitrile gloves and eye protection when working.
• Print and process parts in a well-ventilated area.
• Avoid contact of liquid resin with skin and eyes.
• Do not pour resin residues into drains or sewers – dispose of uncured resin as hazardous waste according to local regulations.
• Study the Safety Data Sheet (SDS) and Technical Data Sheet (TDS) from the manufacturer.

After proper curing, prints are stable, mechanically resistant within the Basic class, and do not pose a skin irritant or cytotoxic risk during normal use.

Post-processing

1. Washing prints – usually in isopropyl alcohol (IPA) or a suitable cleaning solution, approx. 5–10 minutes depending on model size and complexity.
2. Thorough drying of the print after washing (evaporation of IPA / cleaner).
3. Post-curing in a UV chamber according to the printer/resin manufacturer's recommendation (e.g., in CW1S or similar device).
4. After curing, prints can be sanded, drilled, sprayed with filler, and painted, just like other SLA models.

Technical Specifications
