Arptech- RP Service Selection Guide

Rapid Prototyping (RP) is a powerful tool for reducing time to market while improving quality and reducing cost. RP technologies have been matured enough in the past few years, choosing between the various RP technologies can be challenging. We have compiled the brief listing to assist you to select the right technology. Please note NO single method suits every prototyping need and there are trade-offs between these RP technologies. There are numerous prototyping methods but we included only those RP technologies & materials which we use on daily basis. Each prototyping project has a unique situation which may need a combination of tools and technologies. The methods and services listed below are based upon our experience and other RP resources. This comparison should be used as a guideline only. Please contact us for further assistance to select the right process for your project.

Brief about the following Technologies
 Good combination of strength and
surface finish at affordable price and lead time.
 Excellent surface finish suitable for presentation, master models and light functional testing. Range of materials available, soft like rubber to strong like metal. SLS Nylon suitable for snap and living hinge features Use when mechanical properties can not be compromised with any additive RP process. Suitable for general purpose parts for initial design stage with a quick delivery.
