Support Wax Automated Removal Module (SWARM)

Project Background and Design Goal

RIA-JMTC operates two 3D Systems MJP 2500 IC wax printers for investment casting pattern production, but lacks a safe, automated means of removing wax support structures. SWARM automates post-processing through a heated solvent bath with submersed vortex cavitation agitation, sensor-based monitoring, and a touchscreen operator interface. The goal is a self-contained wax removal system capable of processing a standard build plate within 90 minutes for less than $4,000.

Design Outcomes

Designed and developed an automated wax support removal system that integrates a heated solvent bath, fluid circulation, and sensor-based monitoring to control cleaning.

The resulting design provides a complete framework for automated wax removal, enabling controlled testing and optimization of temperature, flow, and process timing to improve consistency and operator safety.

Design Constraints

• Chemical Compatibility: Must safely operate with wax removal solvents without degrading parts
• Temperature: Must maintain solvent temperature between 70-130°F
• Safety & Interlocks: Must include fail-safe hardware and software interlocks
• Size & Dimensions: Working envelope must be at least 14”L x 14”W x 15”D
• Budget: Total system cost must not exceed $4,000
