Molding applications Thermoforming Composite material Molds Injection Molding Blow Molding Prodways Material suitable for molds application on L series: Plastcure Rigid 10500 21

Additive Production of molds : Printing Guidelines Objectives: Additive manufacturing for production of thermoforming / blow molding / injection molding molds Shorter lead-time than standard processes! (down to 2 days for an insert) Save tooling costs on low production volume runs ProMaker printer L-series PLASTCure resin Rigid 10500 Layer Thickness 50-100µm Applications: Validation of mold design, part functionality with the final material Validation of Pre-series, small series Framework: Parts size : small to medium 50 to 100 tons injection molding machines Material injected influences tool lifetime Main competitor = aluminium mold! TIP Thermal Post-treatment might be applied to increase thermomechanical properties 22

Additive Production of molds: Mold fabrication Several technical options are available depending on the molding process. Hollow structure, reinforced hollow structure, backfiller, thermal postcuring, coatings, conformal cooling channels a Partnership with Initial and automotive group for injection molds development. Industrial partnership with leading companies for other molding technologies 23

Thermoforming Molds Manufacturing process used for forming plastic sheet Technical Key points : Recommendation to use reinforced hollow structure Thermal absorption easier to control Vacuum easier to transfer to molding surface Less resin consumed 24

Composite materials molds Molds for Hand lay-up, Autoclave process (RTM) Same technical specifications as molds for Thermoforming. 25

Injection Blow Molding Process used for production of series hollow items (e.g. Bottles) Hollow items blown from a pre-form in an heated blower 26

Injection Blow Molding: 50cl Bottle use case Parting surface printed horizontally Part cavity as upfacing surface ProMAKER printer L5000 PLASTCure resin Rigid 10500 Layer Thickness 100µm Build time Finishing 6,6h (two halves) Support removal Sand blasting More than 250 bottles produced without any damage on the mold. (test stopped requested quantity obtained) 27

Bonus: Extrusion Blow Molding Conformal cooling @5 C Metallic backfiller Closing pressure of 30 bars Blowing pressure of 8 bars Reducing time to market 28

Injection Molding Overview Manufacturing process for producing parts by injecting material into a mold. Injection molding is the most common modern method of manufacturing plastic parts. 3D printed Mold use Capacity of producing between 1 and a few hundreds of parts, depending on the requested thermoplastic material and part design 29

Injection Molding: Test box Results Build time 2x faster than standard SLA (8,5 h) More than 250 parts injected in PP and POM (test stopped) 30 parts injected in PA 30%GlassFiber ProMAKER printer L5000 PLASTCure resin Rigid 10500 Layer Thickness 75µm Build time Finishing 3,3h (two halves) Support removal Sand blasting 30

Metal Casting Process similar to jewelry casting but with bigger patterns. Traditionally wax models are used to create the ceramic mold for metal casting. 3D printed parts with castable resins open new design possibilities for the production of high tech metal components 32

Metal Casting: 3D printing patterns Burn-out process In a traditional mold building process, wax melts away. With the resin pattern, master has to be burned away. Solution Special 3D preparation with hollow structures: Tetrashell Pattern 33

Metal Casting: 3D Value offer Why foundries are interested in 3D printing? Speed : Foundry obtains directly the pattern eliminating 2 steps Freedom of design : Rapid prototyping allows creating more complex shapes Polished casted parts : Resin parts allows a high finishing degree Applications (by importance) Aeronautics and engine manufacturer Orthopedics implants (Titanium) Oil Well drilling equipment Military equipment Artcasting 34

Metal Casting Tetrashell Pattern vs Wax Tetrashell is faster, more complex shapes 3D Material more expensive than wax Adaptation of foundry process required Tetrashell Pattern vs Voxeljet (binder jetting) Tetrahsell has better surface finishing & better dimensional stability Material is more expensive 35

Metal casting : Application Case Production of Turbo Wheel Goal Production of turbo wheels in titanium or inkonel for the after market ProMAKER printer PLASTCure resin L5000 ABS3650 Layer Thickness 75µm Tetrashell parameters Finishing Walls thickness: 0,7mm Leg thickness : 1mm Leg length : 3,5mm Centrifugal Cleaning Support removal Sand blasting 36

Metal casting : Application Case Production of Turbo Wheel ProMAKER printer L5000 PLASTCure resin ABS3650 Layer Thickness 75µm Part per platform 20 Fabrication Data: Production time for 20 wheels : 12h12 Plateforme price : 109 (including resin loss) Production time on SLA system : 16h00 Production in wax (3d printed): 29h30 (less accuracy) Production in wax using molds : NA in this business case 37
