Working with Denture Base Resin PINK-LT
Is Denture Base Resin easy to machine?
Trim sprues and adjust intaglio with carbide acrylic burs or tungsten trimmers at low speed with wet/vacuum dust extraction; avoid heat build-up that crazes the surface.
Can Denture Base Resin be welded?
Not weldable; repairs and relines are done chemically with self-cure PMMA or a matching light-cure repair resin after roughening and monomer wetting.
Can Denture Base Resin be formed, bent or molded?
Print at 25–35 °C vat temperature, 50–100 µm layers, orient the base 20–30° with supports on the polished flange side; wash in fresh IPA (≤5 min total to avoid softening) and post-cure in a nitrogen/glycerin-free UV oven per the validated cycle.
What surface finishes work on Denture Base Resin?
Bond teeth with the matching adhesive resin, then finish with pumice and acrylic high-shine compound; steam-clean rather than boil, and never autoclave or use alcohol-based disinfectants long-term.

Denture Base Resin PINK-LT — frequently asked
What is Denture Base Resin PINK-LT used for?
Denture Base Resin PINK-LT is typically used for removable denture bases, denture try-ins and denture repairs. In short: denture-standard biocompatible resin; full pink shade range; 105 °C glass transition.
What is the yield strength of Denture Base Resin PINK-LT?
Denture Base Resin PINK-LT has a typical yield strength of 45 MPa (6.53 ksi) and a tensile strength of 48 MPa (6.96 ksi) — weaker than 58% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is Denture Base Resin PINK-LT easy to machine?
Reasonably — machinability is rated good (65/100, better than 66% of polymer grades). Trim sprues and adjust intaglio with carbide acrylic burs or tungsten trimmers at low speed with wet/vacuum dust extraction; avoid heat build-up that crazes the surface.
Can Denture Base Resin PINK-LT be welded?
Not readily — weldability is rated not recommended (5/100). Not weldable; repairs and relines are done chemically with self-cure PMMA or a matching light-cure repair resin after roughening and monomer wetting.
What surface finishes work on Denture Base Resin PINK-LT?
Bond teeth with the matching adhesive resin, then finish with pumice and acrylic high-shine compound; steam-clean rather than boil, and never autoclave or use alcohol-based disinfectants long-term.
Can Denture Base Resin PINK-LT be formed, bent or molded?
Print at 25–35 °C vat temperature, 50–100 µm layers, orient the base 20–30° with supports on the polished flange side; wash in fresh IPA (≤5 min total to avoid softening) and post-cure in a nitrogen/glycerin-free UV oven per the validated cycle.
What is the maximum service temperature of Denture Base Resin PINK-LT?
Denture Base Resin PINK-LT is rated for continuous use to about 60°C (140 °F), and briefly to 80°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Denture Base Resin PINK and Denture Base Resin Flex?
PINK is the default condition — default gingival-pink shade, washed and fully post-cured; use for production removable full/partial denture bases. Flex: elastomeric-modified printable base for flexible partials and soft-clasp appliances; not a substitute for rigid ISO 20795-1 Type 1 bases. Yield strength is 45 MPa in PINK versus 15 MPa in Flex.
