Automotive parts supplier gets up to speed on FDM’s capabilities for fixtures Read Case StudyThis article is part of a series on cast urethane manufacturing. You can check out part one here.
In part one, we reviewed the pros and cons of injection molding, citing instances where low volume or short timelines require an alternative production method such as cast urethane manufacturing. Cast urethane manufacturing begins with a master pattern. Usually, that master pattern is 3D printed using PolyJet or Stereolithography (and occasionally Fused Deposition Modeling); however, there are circumstances where a CNC master pattern is required. CNC machined master patterns are preferred over 3D printed patterns when it is necessary to produce more than one or two molds and/ or to meet stricter dimensional tolerances while 3D printed patterns are preferred for more complex parts with faster turnaround timelines.
