By R.J. Viereckl, Michael Gould, Volker Petry, Rich Dodd, Xavier Marguerettaz and Sean Des Roches Rahn USA 3D printing is a technique that has been employed for much longer than one would intuitively expect. Lamination-style creation is a well-known type of printing used in the making of 3D objects, for instance, in clay pot construction. Coils of wet clay1 can be stacked and … [Read more...] about Formulating for 3D printing: Constraints and Components for Stereolithography
3D Printing/PAM
Q. How can new UV-cured chemistries and materials enable expanded applications in 3D printing?
A.Over the past few years, 3D printing (also known as additive manufacturing) has increasingly been a topic of discussion. It’s not hard to see why, as technological advances in hardware, process, software and, of course, materials have caused manufacturers to take notice. Moreover, it’s been the applications of those technologies that have really caught the eye, especially as … [Read more...] about Q. How can new UV-cured chemistries and materials enable expanded applications in 3D printing?
Validating Isotropy in SLA Additive Manufacturing
By F. Timur Senguen, quality/DVT lead, and Chen Wang, materials scientist, Formlabs In the context of additive manufacturing, the term anisotropy is typically used to describe the orientation-dependent physical properties of the printed part. This effect is commonly attributed to the layer-by-layer production method that yields a distinct macro structure in Fused Deposition … [Read more...] about Validating Isotropy in SLA Additive Manufacturing
Q&A: Is All 3D Printing an Opportunity for UV Curing?
By Mike Idacavage, vice president of business development, Colorado Photopolymer Solutions Over the past two or three years, one topic has seemed to stand out in the RadTech universe. Whether it is at the biennial RadTech conference, uv.eb WEST or even this publication, it wont be long before one sees a reference to 3D printing. As the initial UV+EB Technology column … [Read more...] about Q&A: Is All 3D Printing an Opportunity for UV Curing?
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
