Thermoplastics

[special_heading subtitle=”3D Printing” text_align=”center”]Thermoplastics[/special_heading]

Service Overview

The OIC uses Fused Deposition Modeling (FDM) to create 3D objects by continually depositing layers of liquefied thrmoplastics along a tool path defined by a CAD file. Each layer hardens immediately after deposition, and is fused repeatedly to the previous layer until the product is complete.

Thermoplastic 3D printing is an additive manufacturing method that is used to shorten design and production cycles, making the rapid delivery of customized products possible. This technology is fast becoming the preferred method of meeting the growing demand for market-ready devices manufactured in low volume for a wide range of applications.

Common materials in use are ABS, PC-ISO, and Ultem.  Many other off the shelf materials are also available.  Through the development of customized materials, unique properties can be developed for specific applications.

Additional Information

What equipment do you use for 3D printing?

We use the Stratasys FORTUS 400mc 3D Production System. The direct digital manufacturing process employed by the FORTUS system transforms medical grade thermoplastics (PC-ISO) into device prototypes and end-use medical products without the need for machining or tooling. Using the FORTUS system, we are able to streamline product design through fabrication to rapidly produce small volume product runs for prototyping, testing, or end-use.

What is PC-ISO?

Polycarbonate-ISO (PC-ISO) is an industrial thermoplastic commonly used in medical device manufacturing because of its biocompatibility and strength. In its raw state, the thermoplastic meets the ISO 109993-1 and USP Class VI classification 1.
