Rapid Prototyping Service
Rapid Prototyping is a technique used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data. Construction of the part or assembly is done using 3D printing or "additive layer manufacturing" technology.
The first methods for rapid prototyping became available in the late 1980's and were used to produce models and prototype parts. Today, they are used for a wide range of applications and are used to manufacture production-quality parts in relatively small numbers if desired without the typical unfavorable short-run economics.
The CAD-CAM (computer-aided-design / computer-aided manufacturing) workflow in the traditional Rapid Prototyping process starts with the creation of geometric data, either as a 3D solid using a CAD workstation, or 2D slices using a 3D Scanner. For RP this data must represent a valid geometric model; namely, one whose boundary surfaces enclose a finite volume, contain no holes exposing the interior and do not fold back on themselves. In other words, the object must have an "inside". The model is valid if for each point in 3D space the computer can determine uniquely whether that point lies inside, on, or outside the boundary surface of the model. CAD post-processors will approximate the application vendors’ internal CAD geometric forms with a simplified mathematical form, which in turn is expressed in a specified data format which is a common feature in Additive Manufacturing: STL
At 3DPRINTSONDEMAND we put quality first. We will check your STL files for possible errors and fix them for you prior to them being 3D Printed.
You may rest assured that your prototypes will 3D Print exactly as you designed them, from the first time!
