RenShape Helps People Listen in Comfort

When Cresilas, one of the leaders in fabricating models and prototypes using rapid prototyping, was looking for an epoxy resin to secure the component parts of a new design of headset using stereolithography technology, it chose RenShape SL 7811.

In a matter of hours, stereolithography technology is able to produce models and prototypes by using resin liquid, which is polymerized by an ultra violet laser. Objects are created by stacking successive layers one upon the other at an appropriate rate for the creation of the model. As well as assembling parts, substantiating hinge development and constructing models in full form, its value lies in providing a true rendition of the original design concept.

Cresilas was posed with a significant challenge in taking the design concept of the headset through to the commercialization phase in a period of one week. This involved assembling the component parts and finishing the headset to an ABS-like appearance that matched the overall design and functions of the final product, so that the packaging requirements could be realised as quickly as possible.

Commenting on the choice of resin system, Elisabeth Rey of Cresilas said: “With its low-viscosity and surface tension, RenShape SL 7811 allowed for even and smooth layers of resin to form across the component parts during the recoating stage. Most impressively, it did not leave any bubbles on the surface. The parts exiting the machine could be cleaned easily and the sanding finish was easy to perform and therefore much faster as a result.

This system met every target we set it, from creating aesthetically pleasing, durable white parts with a high quality appearance to producing an ergonomic headset design that offers great comfort when used frequently and for long periods of time.”

The versatile family of RenShape SL 7800 resins provides customers with easy processing and excellent, long-term durability.
