Angled acrylic components are widely used in prototyping and fabrication; however,
small scale bending processes are often performed manually, leading to inconsistent
bend angles, overheating, and material waste. The ATTACC was developed as a compact,
reliable system capable of producing precise, repeatable bends at specified lengths.
Inspired by industrial sheet metal bending systems, SHARCC Systems designed a controlled
positioning mechanism that feeds acrylic into a designated heating zone where it is
clamped, uniformly heated, and bent to a precise angle. Prototyping involved repeated
testing to evaluate how acrylic reacts to heat, its optimal heating duration, and
bend accuracy. Testing revealed that heated acrylic exhibits significant elasticity
and tends to spring back after bending; therefore, the bending arm must remain fixed
until the material cools to maintain the desired angle. The final prototype achieved
consistent, repeatable bend angles and reduced material waste compared to manual methods.
ATTACC demonstrates that controlled heating combined with automated mechanical movement
significantly improves precision, efficiency, and overall fabrication quality.
