    • 1. C2C{Network Study visit Fablab Leuven – July 13, 2010 Additive production technology and sustainability: challenges and opportunities Prof. Karel Van Acker, K.U.Leuven Materials Research Centre
    • 2. context: Plan C
      • Flemish Transition Network Sustainable Materials Management
      strategic visions 2030 closing the circle tailor-made materials service economy conscious society green plastics phase 1 phase 3 phase 2 learning & upscaling
      • Long term vision as framework for short term actions
      • Room for high risk experiments in niche sectors
      • System innovation approach
      • Active role of all relevant actors
      visionary leitbild 20xx 2009 experiments
    • 3. context: Plan C knowledge/control material flows extended materials responsibility reverse logistics design for cycle biomimetic materials biobased materials 2030 smaller transparant material cycles 2008 uncontrollable, obscure, global material flows 1:1 production 1000:1 production revalue local production neighbourhood labs bottom-up production just-in-need production modular production closed material loops technosphere biosphere
    • 4. Material wasting production mining production use phase End-of-Life resources waste
    • 5. production
      • e.g. aerospace industry
        • classical machining
          • buy to fly ratio up to 15:1
          • cooling lubircants (Germany: 75 ktonnes/yr)
        • casting
          • energy consumption of holding molten materials
          • tooling
        • molding
          • tooling
          • cooling and mold release components
          • design restrictions
    • 6. what is additive manufacturing? (3D printing, rapid manufacturing)
      • polymers
        • Stereolithography (e.g. photopolymers)
        • Selective Laser Sintering (e.g. nylon powder)
        • Fused Deposition Modelling (e.g. extrusion of ABS)
      • metals/ceramics
        • Selective laser sintering/melting
        • 3D fibre deposition
    • 7. Materials used
      • General: High density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP), unplasticised polyvinylchloride (UPVC), ABS, polylactic acid (PLA) and polycapralactone (PCL) steel, titanium, aluminium, …
      • Can the materials cycle be closed?
    • 8. Materials used
      • Can the materials cycle be closed?
        • process waste can be recycled
        • use of bio-based materials

      • material effectiveness
      • use of biobased and recycled materials – underway
      • waste/emission minimisation during production
      • freedom of design
        • further reduction of material need + very complex geometries possible
        • make use phase efficient e.g. complex lightweight constructions
    • 13. Strenghts of additive production
      • material effectiveness
      • use of biobased and recycled materials – underway
      • waste/emission minimisation during production
      • freedom of design
      • repair of components
        • transport of bytes instead of materials reduce logistical requirements by shortening the supply chain and minimising the need for waste material disposal or recycling;

        • economic
        • stock can be reduced to low value raw material
        • local production, since labour cost is not decisive
      • social
        • personalised products – more added value ??
        • you can make almost everything yourself  Fablab
    • 15. Weaknesses of additive production
      • Energy consumption
      • Technological drawbacks
        • slowness
        • poor surface precision
        • cost
    • 16. Weaknesses of additive production
      • Energy consumption
      • Technological drawbacks
      • Closing the loop
        • there is a huge potential to use this technology for C2C, however still a lot of research has to be done
    • 17. Weaknesses of additive production
      • Energy consumption
      • Technological drawbacks
      • Closing the loop

    • 22. To Conclude
      • Additive manufacturing bears the opportunity to be a truly supportive technology for C2C, BUT also to be a new source of unsustainable production
      • The transition of production technologies towards this (and other kinds of) personalised production is ongoing
      • How will we make this transition growing into a sustainable direction?
