Materials science,
and the ability to prove it
The performance of a photopolymer is not a number on a formulation sheet. It is the product of chemistry, cure kinetics, mechanical design and process window. This page explains how we understand and control all four.
Photopolymer design
Monomers, oligomers and photoinitiators together determine cure speed, shrinkage and final mechanical behaviour. We optimise initiation separately for 385 nm and 405 nm sources so the same material keeps a stable process window across machines.
Mechanical engineering
Toughness, stiffness, elongation and heat resistance are in constant tension. By tuning crosslink density and the hard/soft segment ratio, our high-toughness system holds 65–80% elongation at break while keeping flexural strength above 35 MPa.
Testing & validation
Mechanical data are generated in our own laboratory using ASTM methods. Thermal data separate short-term HDT from continuous service temperature. Dental accuracy is measured as tolerance and match rate after 15 days of storage, not as a same-day snapshot.
Printing & post-processing
Exposure, layer height, washing and post-cure energy jointly decide final properties. We publish a starting exposure window and post-cure guidance for every material — and where a parameter is not documented, the product page says so instead of filling the gap with a guess.
How we describe data
Every value on a product page comes from internal technical documentation, with test item, unit and test conditions. Where the documentation does not provide a value, the page states “not provided”. We do not extrapolate, and products do not share numbers.
Thermal data distinguish two concepts: heat deflection temperature (HDT, short-term at 0.45 MPa load) and the temperature a part can hold continuously without deformation or cracking. They are not interchangeable, and product pages state both.
We do not display certification marks we have not obtained. Compliance and management-system documents — RoHS, REACH, ISO — as well as third-party test reports are available from sales or technical support on request.
