DS : Brake fluid tank

High performance prototype of brake fluid tank using Selective Laser Sintering Technology


Markets: SLS Prototyping and Rapid Manufacturing (Automotive)

Polymers: PA 12, PE


Key performances:

Prototype close to injected part

  • surface smoothness
  • chemical resistance
  • mechanical resistance

Raw material efficiency

  • refreshing rate
  • powder re–use

Efficient Selective Laser Sintering prototyping include part performances and process optimization.

The prototyping manager of MECAPLAST explains why he switched to Innov´PA powder for their internal SLS, detailing the main benefits:

  • Tank prototype resolution and performances
  • Process optimization




High resolution and performances of tank prototype with Innov´PA

MECAPLAST Rapid Prototyping Manager: «A quick sand-blasting and the part is ready for the test»

Tank prototype made out of Innov´PA shows a high level of resolution leading to:

  • a high part surface smoothness
  • easy assembly steps to prepare validation tests (cap and floater assembly)
  • Similar wall transparency to injected PE tank


MECAPLAST RP Manager: «Innov´PA Prototype behaved liked PE injected tank!»

Innov´PA prototype delivers key final performances of a break fluid tank such as:

  • chemical resistance:
    • no fluid leak during tests
    • no corrosion from solvent contained into break fluid «DOT4»
  • mechanical performances:
    • PE-elasticity and flexibility reached (young modulus > 1550Mpa)
    • mechanical resistance of the tank fixation under constraint


Costs savings and Productivity with Innov´PA powder:

MECAPLAST RP Manager: «Processing Costs have been significantly optimized with Innov´PA since 2 years»

Mecaplast observed significant cost savings due to:

Raw material consumption reduction thanks to:

  • a refreshing rate reduced from 50% to 30 %
  • a number of powder re-use after sifting enhanced from 4 to 8 times
  • a decrease of 1/3 of amount of wasted powder

Increased productivity thanks to:

  • a higher number of parts built (up to 400 units per job!)
  • a reduction of secondary steps (cleaning and finishing)
  • less machine maintenance
