History of 3D CAD-Changing the World

In the beginning before Rapid Prototyping….there was the evolution of 3D CAD.
CAD was first developed over 20 years ago with the development of personal computers. The first company to become a leader in the CAD world was Autodesk with a product called AutoCAD. This was the first software product that allowed the user to produce [...]

Need a Good STL File – What is so Important…

Standard Tessellation Language (STL) is a file format native to the Stereolithography software created by 3D Systems. This file format is supported by many CAD software packages and is widely used for rapid prototyping and computer-aided manufacturing (CAM).
STL is a facet-based representation that approximates surface and solid entities only with triangles (i.e., STL files describe [...]

Stereolithography (SLA) Rapid Prototyping Finishes – WaterClear and QuickClear

Rapid prototypes are used for a number of different applications; functional testing, marketing show models, trade show models, etc.  With such wide number of end uses, the type of finish used on the stereolithography (SLA) model becomes very critical.  One of the often overlooked finish option categories is the WaterClear/QuickClear finishes. 
These finishes allow the parts to be [...]

Selective Laser Sintering – Prototype to Production Parts

One of the technologies out there that been gaining momentum in the additive fabrication space is Selective Laser Sintering (SLS).  Over the past few years this process has transitioned from being looked at strictly as a rapid prototyping solution to now being considered for rapid prototyping and final end use production.  The aerospace and industrial [...]
