By Amos Dudley, applications engineer, and Jon Bruner, director, digital factory, Formlabs Modern high-precision lenses are fabricated using a process pioneered by ancient Egyptian artisans: glass, plastic or crystal is ground and polished using progressively finer abrasives until it meets a specified shape. Of course, state-of-the-art lens-making involves sophisticated … [Read more...] about Seeing Clearly with 3D-Printed Lenses

Q&A: How Can the Orientation of UV Lamps in a 3D Curing System be Described?
by R.W. Stowe, UV Applications Engineering Consultant, Heraeus Noblelight America LLC There is a useful language. Life in the UV curing world was easier when UV lamps only stretched across a web or flat conveyor, and all we had to worry about was width, number of rows and distance from the work. But, as we move into 3D processing of complex shaped objects, lamps are located … [Read more...] about Q&A: How Can the Orientation of UV Lamps in a 3D Curing System be Described?
EHS Guide Enhances Safety for Users of UV-Curable 3D Printing
By Nancy Cates, contributing writer, UV+EB Technology Increasingly, 3D printers are being used in non-laboratory settings such as libraries, schools or workshops. While many different technologies are used in 3D printing, UV-curable 3D printing is one of the easiest ways to print high-quality objects with superior resolution. The rapidly decreasing cost of the equipment has … [Read more...] about EHS Guide Enhances Safety for Users of UV-Curable 3D Printing
New Oligomers for 3D Printing Inks
By Heather Francis, chemist, and Ahmet Nebioglu, R&D manager, Dymax Corporation Abstract 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, … [Read more...] about New Oligomers for 3D Printing Inks
