Working with Low-Odor Bio-Based Resin RIGID

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.

What surface finishes work on Low-Odor Bio-Based Resin?

Sand 400→2000 grit wet, then primer/acrylic clear or spray paint; a UV-blocking clear coat is essential outdoors to limit yellowing and embrittlement.

Low-Odor Bio-Based Resin RIGID — frequently asked

What is Low-Odor Bio-Based Resin RIGID used for?

Low-Odor Bio-Based Resin RIGID is typically used for desktop hobby printing, classroom/office printing and low-VOC workshop use. In short: lowest-odor SLA resin; partly bio-based feedstock; more ductile than standard resins.

What is the tensile strength of Low-Odor Bio-Based Resin RIGID?

Low-Odor Bio-Based Resin RIGID has a typical tensile strength of 55 MPa (7.98 ksi) — stronger than 61% of polymer grades. Strength varies by condition: see the 6 listed tempers.

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

Not especially — machinability is rated poor (30/100, worse than 87% of polymer grades). 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 RIGID 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.

What surface finishes work on Low-Odor Bio-Based Resin RIGID?

Sand 400→2000 grit wet, then primer/acrylic clear or spray paint; a UV-blocking clear coat is essential outdoors to limit yellowing and embrittlement.

What is the maximum service temperature of Low-Odor Bio-Based Resin RIGID?

Low-Odor Bio-Based Resin RIGID is rated for continuous use to about 80°C (176 °F), and briefly to 80°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
