Qualification of FDM End-Use Parts for Home Appliance Industry

Problem Statement

The company aims to produce on demand 3D printing parts to help manufacturers in the home appliance sector to reduce spares inventory. To achieve this, the company needs to solve the two limitations of direct production through 3D printing:

  1. The ability to industrialise final parts according to high quality specifications (mechanical, dimensional, visual)
  2. The ability to demonstrate consistent level of quality in production over time and over multiple machines sometimes in different locations (process control)


This pilot project aims to demonstrate the technical and financial viability of FDM 3D printing for spare parts production by taking 19 parts from Electrolux product line for case studies.

Average standard deviation on all parts and dimensions: 60 microns
Average standard deviation on all parts and dimensions: 60 microns

Key Benefits/Outcomes

  • Developed a complete quality assurance system from engineering to production to ensure consistent 3D printing quality.
  • The production process could systematically produce parts reaching the industrial tolerances up to 100 microns
  • Developed a simulation process that can help in the decision-making process to select parts appropriate to 3D Printing and shorten the qualification process of mechanical parts by simulating instead of performing actual tests.

Potential Application

Results of the study could be used to engage on a deployment phase with Electrolux and to enlarge business with other home appliances manufacturers such as Arcelik, Whirlpool, Haier etc.
