Use honeycomb internal structures for model material reduction without losing strength! The honeycomb sandwich construction is one of the most valued structural engineering innovations developed by the composites industry. Used extensively in aerospace and many other industries, the honeycomb sandwich provides the following key benefits over conventional materials: – Very low weight – High stiffness – Durability – Production cost savings In figure one, you see an adhesive surface and facing skin. If you compare this to a part built […]

Stratasys PolyJet 3D Printed Injection Molds….A Series (part 3)

EmailFacebookLinkedInTwitterShare

In the previous posting of this series we finished with the statement "in the next posting we will discuss molding with the PIMT". Once again, I would like to remind you that Stratasys PIMTs are not production tools, however they provide a clear advantage, being both cheaper and faster when a limited quantity of production parts is needed". INJECTION MOLDING Injection molding with a PolyJet mold requires adjustments to the molding process. It is important to start with conservative values […]

CATI is proud to announce a new addition to our 3D printing lineup………. Have you ever lost time and money rebuilding parts because surfaces were not stitched together before exporting an STL file? Or, could there be design errors in geometry received from a customer's file or design from another division of your company? Would it be advantageous of having a "file checker" included into your printing workflow? CAD programs use a number of different set of mathematical definitions of […]

What if your plastic material requirements for your production parts are more than what rapid prototyping/additive manufacturing technologies can produce? What if you need low volume, say 100 parts in your production material? What alternatives are available? One method would be to use injection molding. The injection molding process is very fast and therefore very economical. Yet, every part needs its own costly injection mold making injection molding viable only when mass-production is needed (usually more than 10,000 parts). Injection […]

CATI unveiled the new Alaris30 3D printer manufactured by Objet Geometries at the 2008 Pack Expo show in Chicago to great reviews by attendees.  Throughout the five day exhibition the printer was building parts during show hours and it was fun to watch people stop in their tracks to get a closer look.  The reaction reminded me of the good 'ol days when stereolithography was first introduced and people crowded around to look at this "new" technology.  On more than […]
