Modern Solutions: Scanners and Mesh Software
We often scan physical models with our highly accurate Creaform scanners and create a mesh file or “.stl”. These mesh files can be converted to parasolids or “dumb solid” models through GeoMagic DesignX, a specialized package from 3D Systems not always available to device engineers (as they design devices not bones).
At OsteoShape, we can then use boolean subtraction techniques to correctly orient and create cavities for your instruments and implants within the parasolid. We then send you a rendering of the bone with the implant to verify.
A Star is Born: the SLA “Master” With High-Resolution Finishes
SLA rapid prototype printing is our preferred method to create highly accurate 3D models with high-resolution surfaces. The process converts liquid plastic into a solid 3D model using stereolithography.
Using the printed prototypes as the master to make molds, we verify the fit of the devices after casting the part in thermoplastic materials which involve shrinkage.
A Star is Cloned: Molded & Casted Parts
We are experts at reproducing anatomic shapes, using silicone molds or “soft tools” to produce parts. In small production runs, this is often the preferred method.
For example, injection molding simply does not work when producing scapular or pelvis specimens as they involve unique drafts and undercuts leading to parts being trapped within the molds. A silicone mold will flex to allow the release of the part.
