Dental Sand A1-A2 and A3 resin is PMMA-like micro filled composite resin, made of biocompatible raw materials, with color close to A1-A2-A3 according to Vita scale.
It has high hardness, 90 Shore D, and high tensile strength, stable to mechanical stress and chemicals
Recommended for printing of temporary crowns and bridges. Low odor and absence of harmful monomers allows to print in the laboratory with no need for special equipment.
Russian certification. Currently under European certification process.
COMPATIBLE WITH MAIN DLP/LCD 3D PRINTERS
3D printing settings on most widespread 3D printers

UNIQUE MECHANICAL PROPERTIES
Very high hardness, tensile strength, abrasion and scratch resistance due to ceramic fillers.
Resins are odorless and cause no irritation, so you can work with natural ventilation without specialequipment.
Depending on postcuring A1 or A2 color is achievable. It is stable for long time even in contact with aggressive agents.
Produced from bio-compatible raw material used in photopolymer teeth fillings. Meets standards ISO 10993. Currently under European certification process.
Resin is stable to solvents, aggressive inorganic agents like acid and alkalis.
Pigments and fillers are well stabilized, no sedimentation and flocculation occur, no foam appears.
Correct post-processing process for temporaries
To remove excess resin, wash the 3D printed part in an ultrasonic bath with the TEK1960 * solvent cleaner for 2 cycles of 2-3 minutes.
Do not soak in acetone. Do not leave the 3D part soaking in the liquid. Use a soft brush if necessary.
Dry with compressed air.
Heat for 10-20 min in oven at 60 * C
Perform post-curing in a oven with turntable and 36-48 W UV LED lamps for 30-60 minutes
Polish and apply protective varnish (eg Optiglaze)
*We do not recommend the use of denatured or isopropyl alcohol (IPA). It is very aggressive on the polymerized resin and it could weaken the structure of the 3D part. It is also flammable and potentially harmful to people and the environment.
Store the resin in a dry, cool, shaded place out of direct sunlight.
