Design Innovation can provide you with engineering prototypes
made by any of the standard manufacturing processes, plus rapid prototyping
techniques including stereolithography, 3D printing, fused deposition
modeling and selective laser sintering. We can also make machined working
models incorporating repeatably flexible sections and precision snapfits,
either from 3D CAD files or from 2D drawings. While not illustrated in
the photos below, we've had excellent prototype success with fused deposition
modeling, which can produce parts with physical properties close to those
of injection molded parts.
We have ongoing business relationships with rapid prototype
service providers who can generally ship prototypes in under 48 hours.
From any of these rapid prototype models, limited-use silicone molds can
be made to provide cast urethane parts for detailed prototypes or even
first production. We have a network of manufacturers with a proven history
of delivering high quality, cost-effective parts. Assembly of prototypes
and short-run production is performed by Design Innovation to strict quality
standards. We are able to make prototype units and trade show models that
look and feel like actual production units.

Stereolithography and Urethane Prototypes
- The model on the left is made with the SLA (stereolithography)
process, which was very economical for quickly validating the 3D CAD files.
The physical properties of a rapid prototype are generally inferior to machined
models, but in many cases working prototypes can be built from them, as
was done in this project. In the center model, a set of the SLA parts were
used to make silicone molds from which urethane parts were cast, detailed
and then assembled, allowing realistic display and demonstration at a trade
show while the production molds were under construction. The image on the
right shows the production unit. |
