3D LifePrints use of 3D technology

3D LifePrints has to 3D print in extremely challenging environmental conditions, in some of the world’s poorest countries. This means many additional factors need to be taken into consideration when choosing appropriate technology, including:

  • Lack of constant or stable power (outages from 30 seconds to 3 days)
  • Fluctuating power meaning high burn out rate of hardware
  • Dusty environments
  • High humidity levels
  • Security aspects
  • Lack of internet connectivity
  • High cost of shipping and customs
  • Lack of locally available machines and spare parts
  • Long lead times for repairs
  • A need to remotely control machines
  • Portability of machines
  • A need to be relatively in-expensive (often cheaper to buy new than to ship to repair)
  • Rugged in nature (and modular from an electronic component perspective)

Materials

For many years 3D LifePrints used a satisfactory flexible FDM using TPU, in two skin colours for the LifeArm. However, although this material printed well on the majority of our printer fleet, we found it had a number of limitations:

  • The two colours were not very applicable to human skin colours of people in developing countries
  • Had a high moisture absorption rate meaning after 6 months in a humid location the layers started to de-bond
  • Was not medically certified
  • Would deform under higher Direct sunlight conditions as well as experiencing colour fading

We decided to start to make our own filament, and our partners Murex 3D developed Puros-l, a first-of-kind FDM 3D filament.
