Material Selection for Prototype Design and Production

Article Preview

Abstract:

This paper deals with mechanical design and material selection process for experimental milling device used in mechanochemistry. Part of this process is right optimizing shapes and dimensions with used material and manufacturing process. Our selection and design process were considering stress on individual parts, purpose of parts, future upgradability, material cost and manufacturing cost. All these factors were resulting into high usage of materials like PLA (polylactic acid) and alloys based on aluminium. These materials are generally very good for prototyping thanks to their mechanical properties and cost. For parts with high stress expectation we therefore used more durable materials. In the end we describe disadvantages of PLA materials against metals in production.
