Rapid Prototyped Auricular Mold (快速原型模型)

8 12 2011

Heavily inspired by the iRSM Digital Design in Facial Prosthetics workshop in Edmonton, Canada this summer, my classmate Lindsay and I conducted a study on rapid prototyping a digitally designed 3-piece auricular prosthesis mold. We utilized an iCAT to obtain DICOM files of our ear casts and patient treatment site.

The DICOM files were then imported into Materialise Mimics to mirror the existing ear to adapt to the treatment surface. It was then booleoned from a larger cylinder and digitally designed into a 3-piece auricular mold with keyways to ensure proper fitting. A workflow was then created for the digital fabrication of the mold utilizing Mimics.

The STL of the completed mold was sent to a ZPrinter 310 Plus to be rapid prototyped with a high composite powder and binder.

After printing, the mold was retrieved for postproduction work of drying, infiltrating with cyanoacrylate, and sanding for a final finish.

The prostheses fabricated from the rapid prototyped molds will be used to assess anatomical accuracies to the original ear casts and compared to the traditionally fabricated prostheses through wax sculpting. Another assessment will be made on time and cost effectiveness to determine its feasibility for clinical application.





Visual Word Form Area (視覺詞形區)

Graphic Design Assignment 5: Concept Communication Piece

Purpose: Express the following through type, image, graphic elements, and/or CMYK color.

The part of the brain thought to be responsible for processing visual text may not require vision at all, researchers report in the journal Current Biology.

This region, known as the visual word form area, processes words when people with normal vision read, but researchers found that it is also activated when the blind read using Braille.

Indirect Plant Defense (間接植物防禦)

8 12 2010

Subject: Indirect Plant Defense

When a corn plant is munched by a caterpillar, the physical damage and certain chemicals in the caterpillar’s saliva combine to elicit release of volatile compounds from the corn leaf. This attracts parasitoid wasps that lay their eggs in the hapless caterpillars’ bodies.

Audience: Children in basic science courses of grade school

Media: Animated GIF

GIF animation is an excellent way of illustrating a simple concept while adding a real sense of motion to capture the short attention span of the students. Since animated GIF is automatically recognizable to most Web browsers, schools will only need internet connection for viewing.

This heart may be more appetizing than the pig hearts my classmates and I purchased for our heart assignment.

Started off as a ‘starving artist’ who took a part time job in a bakery, Debbie Goard now single-handedly runs Debbie Does Cakes, a cake design shop which specializes in highly realistic cake sculptures that you have to see to believe.

To make such realistic-looking cakes, Debbie spends a lot of time researching the subject, working from only the actual objects or photographs of them, and carefully creating them as they really are with imperfections and subtleties.
