What is Low-Odor Bio-Based Resin?

Low-Odor Bio-Based Resin is an SLA/DLP photopolymer with reduced volatile monomer content and partly bio-based feedstock, offered in standard, clear, water-washable, tough, flexible, rigid, high-temperature, castable and BIO-MED versions. It is chosen for desktop and shared-space printing where odor and VOC exposure matter, giving 45 MPa tensile strength, 9 % elongation and 82 Shore D — more ductile than most standard resins. Maximum service temperature is 55 °C, the lowest in this family, and the cured thermoset yellows and embrittles under UV without a protective coating. For heat or flame requirements, move to the high-temperature or fire-retardant resins. Low-Odor Bio-Based Resin has a density of 1.15 g/cm³ (0.0415 lb/in³), lighter than 57% of polymer grades. Its glass-transition temperature is 58°C (136 °F). Low-Odor Bio-Based Resin has a tensile strength of 45 MPa (6.53 ksi), weaker than 52% of polymer grades. Elongation at break is 9% and the elastic modulus is 1.9 GPa (0.276 Msi).

Working with Low-Odor Bio-Based Resin

Is Low-Odor Bio-Based Resin easy to machine?

Drill, tap and wet-sand only lightly with sharp tools and low heat; the cured thermoset chips and crazes, so post-cure fully before machining.

Can Low-Odor Bio-Based Resin be welded?

Not weldable — thermoset; join with cyanoacrylate, epoxy or by bonding parts with a drop of the same uncured resin and UV-flashing the seam.

Can Low-Odor Bio-Based Resin be formed, bent or molded?

Print at 385–405 nm with ~30 °C vat temperature and 2–3 s layer exposures, then wash (water or IPA per grade) and UV post-cure 5–20 min at 40–60 °C for stated properties.
