Materials for 3D Printing

Technology Overview

Relying on our understanding in the future of 3D printing and current problem 3D printing materials development, a series of materials for solid and liquid based printing techniques such as fused deposition modelling (FDM), stereolithography (SLA) / digital light processing (DLP) and PolyJet have been developed. These materials technologies enable further breakthroughs in 3D printing. Some examples include:

  • Composite filament which enables the metal and/or ceramic printing using Fused Deposition Modelling (FDM) 3D printer
  • Electrically conductive filament for 3D printing and soldering
  • Polymer resins with unique properties - highly efficient photo-initiation, luminescence; photochromic, thermochromic, hydrophobicity or hydrophilicity

Technology Features & Specifications

Composite filament enables 3D printing of metal and/or ceramic without the use of laser assisted 3D printing

  • Filament can be used on FDM 3D printers
  • The printed 3D objects can be sintered to obtain high density

Electrically conductive filament enables low-resistivity (~0.5 mΩ·m)

  • No post processing required
  • Can be used with standard FDM 3D printers and 3D printing pens

Polymer resins offer various functions:

  • High safety due to less migration of the additives
  • High accuracy in the printing process and long term storage
  • Sensing and monitoring capability
  • Tunable mechanical properties range from elastic to high strength and hardness
  • Tunable wettability range from hydrophobic to hydrophillic

Potential Applications

The 3D printing materials developed are expected to be applicable in (but not limited to) the following areas:

  • Additive manufacturing (e.g. in consumer electronic, biomedical and dental industries)
  • Rapid prototyping and model-making for product design
  • Art / design / sculpture / jewellery
  • Small objects and mould printing
  • Mass customisation
  • Home and office decor
  • Repair services

Customer Benefits

The 3D printing materials developed offers the following benefits:

  • More resin choice and materials selection for significantly broaden the applications of relevant 3D printed objects
  • Cost effective mass customisation (does away with the need for molds)
  • Materials can be used on most FDM 3D printers in the market
  • Easy to implement and broadened applications
  • Can be customised to specific formulations to suit different specifications
  • Allows for make-to-order (MTO) production strategy, reducing inventory holding cost
