Rapid Tooling [1], [3], [4] is the technology that adopts RP techniques and applies them to tool and die making. RT technology is classified as a soft tooling process and a hard tooling process according to the applied material. Also RT can be divided into hard direct or indirect tooling. Tooling for short manufacturing

Inspection Methods Overview and Comparison

Comparison. INSPECTION. is an organized examination or formal evaluation exer-cise. In engineering, inspection involves the measurements, tests, and gages applied to certain characteristics in regard to an object or activity. The results are usually compared to specified requirements and standards

higher than with injection moulding, and trimming can be in-situ. A single machine with roll feed and comparatively low cost tooling can easily outperform injection moulding, but very importantly the trend towards multilayer barrier packaging for long shelf life normally eliminates injection moulding. 2.2 Thick Sheet Thermoforming

Masood and Song [5] developed and discussed the thermal characterization of new metal/polymer composite material for use in fused deposition modelling (FDM) rapid prototyping process with the aim of application to direct rapid tooling.

Value chain and production cost optimization by integrating

Comparison of cost per part between injection moulding, SLA, FDM (Fused Deposition Modelling), Selective Laser Sintering (SLS) when applied for direct part production (adapted from [9]). AM for production of single units requires a low initial investment but the cost raises steeply with an increase of the production

Part shrinkage anomilies from stereolithography injection

Stereolithography (SL) has shown itself to be capable of directly producing tooling cavities (inserts) for injection moulding. The accuracy of the SL process results in epoxy inserts that require few further operations prior to their use in injection moulding. Thus, the process provides a quick route to tooling that, depending on geometric

However, they are likely to be representative of results for aluminium tooling for vacuum casting, injection molding and other similar processes. 2.1 Tooling Case Study Results

Quantifying part irregularities and subsequent morphology

Stereolithography (SL) is an RP technique that allows for rapid, direct generation of epoxy and/or acrylic tooling inserts that can be used in injection moulding. The accuracy of the SL RP process results in inserts that require few further operations before their use in injection moulding. Thus, the process provides a quick
