Investment Casting – Rapid Tooling Approach

Rapid tooling route selection and evaluation for sand and investment casting

Today, a number of direct routes using RP processes (FDM, LOM, SLA, SLS, etc.), as well as indirect routes (RP coupled with secondary or soft-tooling processes like RTV vacuum casting) are available for rapid fabrication of tooling for sand and investment casting processes. Each route is unique in terms of geometric, material, quality and cost characteristics; no comprehensive database of their...

Design and Manufacture of Casting Pattern Plates by Rapid Tooling

The primary target of this project consists of combining the technique of rapid prototyping and casting to produce aluminum parts in a sand mold being made the corresponding models and core boxes by means of the technology of rapid tooling, FDM (fused deposition modeling) of ABS. The followed process to obtain the pieces is casting, that consists of the fused metal spill in a mold pattern previ...

Rapid Fabrication of Functional Mouthguard Using Rapid Tooling Approach

This paper presents the fabrication process of custom-made mouthguard with added features of air flow channel by using rapid tooling approach. Impression process was conducted in order to produce dental stone that will be used in thermoforming process to fabricate the custom-made mouthguard. Computer-aided design (CAD) were utilized to prepare the air flow channel’s design before attaching it a...

Rapid Prototyping - Rapid Tooling - Rapid Manufacturing

Investment Casting with Ice Patterns Made by Rapid Freeze Proto

One of the most promising applications of rapid freeze prototyping (RFP) is making metal parts by investment casting with the built ice parts. The integration of RFP and investment casting allows fast creation of complex net-shape metal parts directly from their CAD models. The advantages of doing so include no part geometric complexity limitation, no experience of parting line design and assem...
