Overview

Impact resistance, or toughness, is defined by the relative susceptibility of plastics to
fracture under stresses applied at high speeds. In materials science and metallurgy,
impact resistance is a material’s resistance to fracture when stressed. It is defined as
the amount of energy per volume that a material can absorb before rupturing.

Many of today’s appliances have to endure impact due to how they are used, accidents, safety requirements and more. The impact resistance of plastics can be improved by adding a soft material coating on top of hard plastic materials.

Listed below are examples of typical applications within given industries:
Consumer Goods: Binocular protection, plastic container coverings, all-terrain
  personal equipment.
Consumer Electronics: Outdoor  equipment  for  all-terrain  purposes,  laptops,
  outdoor GPS equipment.
Defense: All-terrain electronic equipment.
Toys: Baby toys, video game consoles, joysticks.

The ability of PolyJet™ Connex™ 3D printing technology to combine flexible and rigid
materials can be used to produce various coating thicknesses and also different Shore values of the coating material. Tests can be performed on the parts to measure the impact resistance obtained by the coating. By using the mixed tray option (rigid and soft  materials  printed  separately  on  the  same  tray),  you  can  print  various design versions with different coating structures, assemble the coatings on the rigid parts and test them to optimize your design.
