Exploring Polymer-Based Additive Manufacturing for Cost-Effective Stamping Devices: A Feasibility Study with Finite...

Area of Science:

• Materials Science
• Manufacturing Engineering
• Mechanical Engineering

Background:

• Traditional metal stamping devices are costly and time-consuming to produce.
• Additive Manufacturing (AM) offers potential for rapid prototyping and cost reduction in manufacturing.

Purpose of the Study:

• To investigate the feasibility of using Material Extrusion (MEX) Additive Manufacturing (AM) for producing stamping devices.
• To evaluate the performance of polymer-based stamping devices using Finite Element Analysis (FEA).

Main Methods:

• Finite Element Analysis (FEA) was employed to simulate the performance of polymer stamping devices.
• The study analyzed devices made from Acrylonitrile Butadiene Styrene (ABS) and Nylon polymers.
• Performance was evaluated based on deformations and angular deviations when stamping metal sheets of varying thicknesses (up to 1 mm).

Main Results:

• ABS polymer devices operate near their material limits under compression, showing significant deviations (up to 1.4 mm and 4 degrees for 0.5 mm sheets).
• Nylon polymer devices demonstrated suitability for stamping thinner sheets (0.25 mm), outperforming ABS.
• ABS devices exhibited substantial angular deviations, reaching up to 45 degrees for 1 mm sheets.

Conclusions:

• MEX AM is a promising technology for the small-batch production and prototyping of stamping devices.
• Further material and mechanical optimization is necessary to minimize deformations and enhance the precision of polymer-based stamping devices.
• Nylon shows greater potential than ABS for applications involving thinner metal sheets.
