Did anyone else notice the CAD they were using is Onshape? And Trimech is a SolidWorks VAR.

High-performance, high-temperature plastic enables a 3D printed injection mold to match the performance of an aluminum mold with the benefit of lower cost and faster production.

New 3D printing method produces commercial grade microlenses with smooth surfaces, which could advance optical device design.

Previously, Trevisan’s complex designs for engine parts or heat exchangers resulted in computer-aided design (CAD) files that were 7 to 10 gigabytes in size. CAD models with a huge number of features, such as extremely refined meshes, stretch the capacity of today’s software with file sizes and rebuild times that increase exponentially with the size of the part.

This marine engine cylinder head, measuring about 500 x 500 x 450 mm, however, was optimized for 3D printing in “computational design” software from nTop, which enabled Trevisan to add the very complex details, such as lattices and internal channels, and to merge parts into one part without multi-gigabyte files. nTop is like CAD software, but more sophisticated in the way it represents part geometry and results in much smaller file sizes.
