Realize SLA Materials Comparison Sheet

“The people at Realize, Inc. understand the meaning behind rapid prototyping. They have always delivered what I needed by the time I requested and some of these requests were incredibly urgent. The quality of their work is always top notch, which always delights our customer. Usually my requests are for very large models that would require multiple cuts and too much time to build on our smaller 250-machine. They have always produced fantastic results. Best of all though has to be just working with their whole company. It is always a pleasure to work with such a friendly, knowledgeable and can-do-attitude group of people. They understand my needs and always deliver a quality product. I would and have recommended Realize, Inc for any of your rapid prototyping needs.”

RTV and Cast Urethane Models

Many projects require a higher quantity of prototype models, or perhaps a more plastic-like material. Silicone rubber tooling is an excellent, more traditional and cost effective method to consider when these types of projects arise. Depending on part complexity, one RTV tool has the capability of producing as many as 25 cast urethane models. There is a wide array of urethanes from which to choose. Urethanes can be clear, colored, rigid, soft, high-impact or temperature resistant. It is even possible to insert metal components into the cast urethane models. These attributes can lead to a high-quality, semi-functional prototype that more closely simulates your end product.

Our process begins by creating a 3D Printed master model which is highly finished. The pattern is then encapsulated by a thick, liquid silicone rubber. Once cured, the silicone rubber mold is delicately cut open to reveal and extract the original pattern. Urethane is typically used to fill the mold creating a prototype model of your part. This can be done until the mold loses viability, which is dependent upon several factors, including part geometry and type of urethane. The RTV process is truly an art.
