Assignment 2 – The Folly

Worth: 15%

Due: Digital files to be submitted at the end of week 5’s class (31st March 2010). Printed models due at the start of week 6’s class (14th April 2010)


The objective of Project 2 is to introduce students to ADDITIVE 3D numeric fabrication processes, focusing on the technique of printing with a 3D PRINTER machine. Each student will a design a small object to be 3d printed at two different scales 1: at architectural model scale of 1:50, and 2: at wearable, jewelry scale. Students are to use the same design to produce the two different scaled models (some minor adjustments may be needed as appropriate). We will be using the free, open source software TopMod3d ( to create our digital models. We will use Magics (installed on RMIT lab machines) to fix and prepare STL files for 3d printing.  The specific requirements for each model are outlined below:

Model 1, architectural scale 1:50

  • Design a small folly, a small building/pavilion constructed primarily for decoration.
  • It should be a max size of 5m cubed, so at 1:50 architectural model scale this is a max model size of 100x100x100mm.
  • Models should be no smaller than 75x75x75mm.
  • This model is to be printed on the ZCorp powder printer at RMIT. (ZCorp bed size : 350x250x200H) + 5mm edge

Model 2, wearable/jewelry scale

  • adjust the design as necessary in order to produce a small scale, wearable/jewelry scale model. (e.g. you may need to add fasteners or chain loops to create a pendant piece)
  • max model size: 40x40x40mm. there is no minimum – however you will be limited by the machine and material restrictions.
  • Models to be printed either on RMIT’s OBJ printer, or through a third party (e.g. Shapeways) in acrylic, plastic, resin, or stainless steel as appropriate.

Submission 1: end of week 5’s class (31st March 2010).

  • Digital STL file
  • screenshot in Magics showing no errors in the file

Submission 2: start of week 6’s class (14th April 2010)

  • the two printed models
  • two renders/photo-montages of your design
