3D Printing and Science

Research to improve the fff (fused filament fabrication) process


There is a need for more scientific results for the fff process that is used for many home 3D printers. This is the technology when a plastic filament on a spool is melted and extruded out of a small nozzle to form a real part. I think that I can contribute with some results that might help someone.


I have worked with 3D printing since 1990 and developed two processes for industrial metal printing. Now I can see a need for more knowledge in the area of printers used in the consumer market that will drive the awareness of the technology forward.


The core of the fff process are

  • Material
  • Extrusion

To enable a good result from the core process it has to be supported with several functions

  • Mechanical parts
  • Software
  • Electronics
  • Temperature control
  • Humidity control
  • Many more things ….

To investigate these different aspects I will do measurements and experiments, many focusing on material and extrusion. I will document them in the blog and also as pdf-reports.

Science is simply the word we use to describe a method of organizing our curiosity
