16. Material Research #1 Sculpting, Silicone Mould Making, Resin Casting

I initially wanted to caption this as a technical tutorial, but decided to file it under "Material research" in the end since I don't have the materials to try it out myself. At the very least, it's a look into the methods, and understanding that what I want to make is achievable.

For the heart, Julian had mentioned the possibility of making a mould directly from an animal's heart. However, after asking around in 3D Lab 1, I can see how there might be concerns of hygiene, and also trouble creating something of a custom size. Due to that, I decided to go sculpting the heart instead, in different parts, and then combine them. 

This first video is a pretty comprehensive look into sculpting, making a mould out of the master, and then filling that mould with resin. For my purposes my final product needs to be silicone rather than resin, so I'll need to look into that. However, the video shows how to tape together a silicone mould properly when filling it, so that's beneficial.

This tutorial shows an example of releasing a silicone piece from a silicone mould. There are useful recommendations of what kinds of release chemicals to use, and how to get it properly applied into the mould. This tutorial also adds some flocking into the mix to help create a realistic skin texture.


This video shows a step-by-step of sculpting a somewhat realistic looking heart.

1. Initial Ideation

Image
As a part of the first week's exercise, I started thinking about what I might make for my final year project. According to the handout given during the Level 6 Induction, and IMD final year project needs to fulfill these requirements: Interactivity and coding. This means that I'll need to create something which reacts to a user's input, created with the use of code and digital media. The final year project also needs to demonstrate skill, reflect my interests; be related to my intended career field; fit into a professional portfolio; fit into my available time frame and resource level; and most importantly be memorable to users. The activity of the first week's lesson was to think about problems we've noticed in a game, app, or museum experience and suggest possible solutions. We also needed to ask the opinions of our classmates to see if they agreed with the problem and proposed solution. Finally, we were asked to think of problems we faced personally and conside

Things I'll need basically Software Arduino IDE  - to edit and load code onto the Arduino Uno Adobe Photoshop - Creating assets Adobe Illustrator  - Creating assets (will probably use this more) Unity  - Making the interface Adobe Audition - editing audio files FL studio  - creating audio loops Hardware  Arduino Uno - it's the brain! Easy MP3 Shield - helps play the required audio files Wires - connections  Buttons - or rather, whatever sensors I end up using CPU  - powers the screen/interface Monitor  - the screen, for people to see things Power tools  - cut cut drill drill sand sand Sculpting equipment  - to make the sculpted heart Project Outcomes This artefact will be a physical installation. The torso of a mannequin will be suspended from the ceiling, with its electronic guts hanging out and holding a heart in its hands. The heart will be the controller of the installation, and the main thing that users i
