To form complex mandrels for composite tooling, materials such as SR-30 (FDM) and DMX 100 (SLA) are starting to gain traction and, with the right knowledge and experience, these materials can perform wonders. SR-30 is a sacrificial mandrel and DMX is an extraction mandrel with some unique properties.
How much will building manufacturing tools cost?
The cost to build a tool is generally determined by the size of the tool, not its complexity. As an example, an iPhone sized tool would cost around £30, whereas an iPad-sized tool would be £240.
