Ask about this product

Prusament BioBased60 is an eco-friendly resin for 3D printing developed by Prusa Research, designed to offer maximum precision with a lower environmental and health impact. It is a photopolymer resin ideal for MSLA 3D printers, with a formulation based on 60% plant-based ingredients, making it one of the most bio-based resins available on the market today. It is an ideal product for applications that require a very high level of detail and a low-odor, low-toxicity working environment.

Thanks to its acrylic monomers derived from natural oils and terpenes, such as α-pinene extracted from pine, this 3D printing resin produces a soft, non-aggressive aroma, avoiding the strong chemical smells typical of conventional resins. Its BPA-free composition and low toxicity make it a safer option for home, educational, and creative environments. It is especially suited for those seeking a 3D printing material with minimal health impact.

Ideal resin for modeling and hobbies

Prusament BioBased60 is a perfect resin for 3D printing action models, miniatures, and decorative parts with exceptional detail. Its high precision allows for the creation of intricate components for hobby projects or complex models. In addition, the ease of sanding, both dry and wet, facilitates post-processing and improves the final finish of each piece.

It is also a stable and reliable product throughout the printing process, with a notably low exposure time: only 2.8 seconds per layer when used with the Original Prusa SL1S SPEED printer, thus optimizing speed without sacrificing quality. Some of the most prominent applications of this resin are:

Rapid prototyping. Thanks to its short exposure time and excellent layer-by-layer definition, this bio-based resin is ideal for fast 3D printing of functional or conceptual prototypes. Its use in MSLA printers enables the fabrication of complex geometries that would be difficult to replicate with FFF/FDM technologies, significantly reducing total production time without compromising quality.
Mold making. Prusament BioBased60 resin is also suitable for creating casting molds. It can be used to print master models from which silicone molds are made, or to directly manufacture functional molds. This versatility is especially useful in applications such as casting, product design, functional art, or small-scale craft production.
Educational models. The low odor during printing, BPA-free formulation, and reduced health impact make this resin an excellent choice for educational settings. It enables printing of highly detailed anatomical, technical, or scientific models suitable for teaching purposes in schools, universities, or technical training centers using 3D printing.
Art and design. Prusament BioBased60 excels in reproducing delicate structures with precision, making it an ideal material for artists and designers. It is perfect for decorative objects, creative prototypes, small sculptures, or any project where aesthetics, detail, and fidelity to the original design are a priority. Its ease of use allows complex ideas to be transformed into high-quality physical objects.

Although prusament biobased60 has been specially designed for the original prusa sl1s speed, its formulation is fully compatible with other msla 3d printers on the market. however, when used with the sl1s speed, faster printing speeds are achieved without compromising detail quality, thanks to its monochrome screen and fast tilt mechanism.

Recommended exposure settings
for optimal results, it is recommended to use the official prusaslicer profiles. exposure times vary depending on color and printer model:

Color	Original Prusa sl1	Original Prusa sl1s Speed
Sapphire blue	8 s	3 s
Obsidian black	12 s	6 s
Ivory white	9.5 s	3.5 s

Under ideal conditions, the sl1s speed can reduce exposure time to just 2.8 seconds per layer, speeding up prints without sacrificing resolution.

Material usage
to optimize resin use, it is recommended to apply the hollowing function in prusaslicer. this technique saves material and facilitates curing, provided that proper drainage holes are generated and vacuum effect is avoided during printing.

Sanding and post processing
once cured, the resin can be easily sanded both dry and wet, allowing improved surface finish on detailed models or functional parts.

Safe resin handling
before use, shake the bottle well to ensure a homogeneous mixture. it is essential to use nitrile gloves and avoid direct skin contact. in case of contact, rinse the affected area immediately with water. handling without protective equipment is not recommended, and it should be kept out of reach of children and pets. use of a mask or respirator is also advisable in poorly ventilated spaces.

Model cleaning
after printing, parts should be cleaned with isopropyl alcohol (90% or higher) to remove uncured resin residue and ensure a clean finish.

Waste disposal
liquid resin should not be disposed of with regular waste. both liquid remnants and materials contaminated with uncured resin (paper, gloves, bottles) should be disposed of at hazardous waste collection points. once cured, resin becomes non-recyclable (thermoset) and can be discarded as general solid waste, but never with recyclable materials.
