Seeing Clearly with 3D-Printed Lenses
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
The Effect of Different Curing Methods on Tack-Free Curing
By Amelia Davenport, Mike Idacavage and Neil Cramer, Colorado Photopolymer Solutions From coatings to biomedical implants to photolithographically controlled materials, photopolymerization has dramatic advantages. It can be utilized for in situ cure materials at whatever time, location and 3D pattern desired. It is one of the most energy-efficient processes known and can be … [Read more...] about The Effect of Different Curing Methods on Tack-Free Curing
Three-Dimensional and Uniform UV Curing Using Integrating Sphere Technology
By Thomas Efsen, managing director, Efsen UV & EB Technology An integrating sphere uses multiple diffuse reflections of light incident on the sphere inner surface to homogenize the light over the entire surface (Figure 1). This results in uniform irradiance at all points on the interior surfaces of the integrating sphere. This has been applied to UV curing by … [Read more...] about Three-Dimensional and Uniform UV Curing Using Integrating Sphere Technology
