Printed press-brake hem/round profile

EQUIPMENT

• FDM printer / slicer
• Slicer project
• Calipers or inspection method

MATERIALS

• Material requires confirmation

STEPS

• Measure the desired finished cross-section, material thickness, clearance and flange length. Distinguish an open hem from a closed hem or a rolled profile.
• Model the sheet and tool sections together, including the approach and withdrawal path. Check for trapped geometry and interference through the entire stroke.
• Print an unloaded profile mock-up to check fit and handling. Keep this geometry-check specimen separate from any tooling authorized to carry load.
• For an actual forming trial, obtain a process-specific load and tooling review; document each forming stage independently.

TROUBLESHOOTING

• A tool that performs a simple V-bend cannot be presumed suitable for flattening a hem. Contact pressure can rise sharply as a hem closes. Do not infer a machine stroke or capacity from the appearance of the print.

SAFETY / LIMITS

• Use qualified judgment and current manufacturer or code guidance for safety-critical work.
