Exploring the potential of 3D printing biodegradable carriages

Abstract

Funerals are increasingly personalized to reflect the life, values, and personality of the deceased, while societal awareness of environmental impact drives demand for sustainable alternatives. Conventional coffins are often made from non-biodegradable materials, and current coffin designs offer limited aesthetic and personal expression.

This project explores 3D printing coffins using a bio-based and biodegradable material to create more meaningful, emotionally supportive, and aesthetically pleasing coffins.

Both coffins and carrying boards are included under the term "carriage." Material properties were studied through Material Driven Design and tensile testing, revealing technical feasibility and a natural, organic appearance appreciated by users.

A journey map, based on interviews with undertakers and bereaved individuals, formed a design direction and goal. The final carriage allows control over the visibility of the body, a gradual closure, and the placement of gifts. The design holds flowing forms, follows body contours and integrates into a nature setting

Strength of the coffin was evaluated through a Finite Element Analysis to optimize weight, cost, and printing time.


User evaluations indicated that the design was aesthetically pleasing than current solutions. Further research is needed on structural strength, cost, and production efficiency to ensure viability
