2 Outline Previously: 3D Sculpting Action Heroes Generating base models Slicing into parts & adding joints Customizing via 3D sculpting tools Today: Recap meshmixer & finish models Preparing parts for 3D printing 3D printing Cleaning up 3D printed parts Adding electronics to 3D printed Action Heroes Make them interactive Electronics & coding

3 Outline Decide on which models you want to use Models you created yourself Adapt models from other sources Use Meshmixer to: Scale models to ~18cm Add joints, magnet mounts and other structural features Add mount points for electronics components Customize appearance with 3D scuplting tools Prepare models for printing & export to STL Orient models for printing How to use the 3D printers How to clean up printed parts

4 Torso joint Slice torso using select tool Mesh mix cylinder to extend torso base Hollow out parts Add strut across inside of torso base for elastic Add length to neck

5 Add magnet mounts Round magnets hold head cap on: 3mm x 1mm Use meshmix tool to add cylinders at least (6mm x 4mm), move into position Add a 3.5 mm x 1.5mm cylinder and use boolean difference to cut out the hole for the magnet Make solid, and use sculpting tools to blend into base model

for eyes, meshmix in a sphere and use boolean difference to hollow out space from

6 LED mounts LEDs are 5mm or 8mm in diameter. You'll have 2 single color and 2 multi-color LEDs to work with If you want to use LEDs for eyes, meshmix in a sphere and use boolean difference to hollow out space from inside the head Use sculpting tools to shape outside of eye sockets You can also use doll eyes, beads or 3D printed eyeballs for eyes

Add magnet & electronics mounts Magnets on feet are 4mm x 8mm cylinders Also add 2mm hole for wires (wires run up the legs from battery holder under feet) Microcontroller is 18mm

7 Add magnet & electronics mounts Magnets on feet are 4mm x 8mm cylinders Also add 2mm hole for wires (wires run up the legs from battery holder under feet) Microcontroller is 18mm x 25mm x 4mm Make sure you cut out a big enough space inside the torso to fit this Also leave space for the piezo buzzer (for beeps and sounds) & wires (11mm diameter x 12 mm high)

8 Button mounts You can add pushbuttons to your figure to trigger different behaviour (e.g. change colour of LEDs) Make space to mount inside head or cut out holes from torso back if you want the buttons to be visible Our buttons are 6mm x 6mm

9 Add insignia Use meshmix tool to merge insignia on to the figure (e.g. Iron-Man style chest medallion) Use boolean difference to punch cut-outs or thin out shell of torso to be transparent if you want to mount LEDs inside chest

10 ANALYSIS AND PREP

11 Meshmixer analysis tools - units Use Analysis > Units / Dimensions tool to check part dimensions

12 Meshmixer analysis tools - strength Use Analysis > Strength tool to assess strength of the part it should be all green

13 Meshmixer analysis tools - measure Use Analysis > Measure tool to measure between any points on the model e.g. to confirm that the magnet mounts are big enough

14 Meshmixer analysis tools - Inspector Use Analysis > Inspector tool for basic repair of holes

15 Orientation Select Analysis > Orientation for automatic orientation

16 Fixing problems Models need to be manifold to print (i.e. could exist as objects in the real world). Avoid: Extra internal faces Holes in the mesh e.g. faces not properly connected Remove internal faces: Use Make Solid tool Holes: Use automatic repair or use select tool to select sides of hole, then use Bridge tool to fill them in Thin walls: Use select and then Edit > Extrude tool to thicken walls Use NetFabb Basic auto-repair as a final step if your part has problems. They also provide an online repair service:

Printers will generate support, or we can manually add it

17 Overhangs & Support Overhanging parts will need support so they don't suffer the effects of gravity The Up! Printers will generate support, or we can manually add it to the model Select Print Transform & Move to Platform Add Supports

18 Export to STL Export to STL format for 3D printer via Export button on Print screen, or via File > Export. Then import STL into Up! software

19 Next steps Make a list of all parts required Prepare printable versions for all parts Create mirror versions for left/right feet, limbs, hands Add your models to the USB stick Next session: Adding electronics Soldering Microcontroller programming Assembling the figures Decoration: hair, eyes, costumes We'll discuss options for painting/finishing 3D printed parts, if you want to paint your figure after the workshop
