New Oligomers for 3D Printing Inks

The present work addresses a strong market demand for oligomers for 3D printing formulations. Structure-property relationships in a new family of oligomers will be discussed. Effect of oligomers on oxygen inhibition, coefficient of thermal expansion, heat distortion temperature, shrinkage, and color stability will be revealed. Some of the formulations based on the various new oligomers are very fast curing and prone to substantially less oxygen inhibition. They demonstrate good adhesion to different substrates and possess very low water absorption characteristics.
