Puppet-Lamp

Computer Aided Manufacturing Project : utilizing 3D printers and laser cutters.

Lampshade Modelling

• Hexagonal Structure on the surface.
• Join the curve of Hexagonal Lines.
• Create a pipe surface around a rail curve with 0.5 cm radius.

• Hexagonal Structure to decorate lampshade surface in Grasshopper.

• Concepts & shapes of lamp model.

• Rendered display mode of these lamp model.

• Final program of lamp modeling in Rhino 7.

Lampshade Printing

SET-UP

Printer: Prusa i3 MK3S

Print settings:

• Layer Height: 0.2 mm
• Wall Thickness: 0.8 mm
• Infill Density: 5.0 %
• Infill Pattern: Grid
• Printing Temperature:200.0°C
• Print Speed:60.0 mm/s
• Initial Layer Speed:30.0mm/s
• Build Plate Adhesion Type:Skirt

• Top view of lamp shade model for the simulation slicing for 3D printers in Ultimaker Cura.

• Right view of lamp shade model for the simulation slicing for 3D printers in Ultimaker Cura.

• The slicing lamp shade model in line type of color scheme for 3D printers in Ultimaker Cura.

Result

• Too thin of a wall is easy to collapse the bottom and support structure.
• The printing path in the Z-axis value is over setting.
• The initial speed is too fast to make sure a completed printing process.

• printing process and result of lamp shade model in PLA.

Solution

• Utilize “offsetsrf” command to thicken the surface into
• Reduce the speed by tuning the 3D printer setting after the 9 times calibration of horizontal foundation.
• The initial speed is too fast to make sure a completed printing process.

Neck x Joints Modelling

• Made by 3D printers with PLA.

Neck x Joints Printing:Test_01

SET-UP

• Layer Height: 0.3 mm
• Wall Thickness: 0.3 mm
• Infill Density: 10 %
• Infill Pattern: Triangles

Printer: Prusa i3 MK3S

Results:

• Easy to break between layers
• Wall should increase density
• Infill is not enough to be a joint (20~30%)

Neck x Joints Printing:Test_02

SET-UP

• Layer Height: 0.2 mm
• Wall Thickness: 0.8 mm
• Infill Density: 20 %
• Infill Pattern: Triangles

Printer: Prusa i3 MK3S

Results:

• Overly strong support
• Wall (top) quality is still poor
• Support is not as expected

Body&Leg: Laser Cutter

Modeling:

• Topological interlocking in assembly procedure.

Tool:

• Laser Cutter

Material :

• White-grained Wood

FINAL SET-UP

Cutting Power : 75% Cutting Rate : 4%

• Layout of model and result.

• Assembly of outcomes by laser cutter.

Result:Combination

3D Printers

• The joints are still not strong enough to resist long-term using.
• After thicken the lampshade, the weight distribution unbalanced.

Laser Cutter

• The deviation of laser cutting makes the combination between body and joint just fit-in.
