New Year, Clean Room
With summer vacation fully underway, ArtFab blue is getting cleaned out and reorganized for another year of creating! (and we have new whiteboard tables!)
CNC Plaque Engravings
The CNC router is not only a powerful tool for building, but also a great way to prototype. As shown in the example below, techniques such as engraving and roughing have been employed to create a sample plaque. In this particular design, a botanical sketch of a fern is shown highlighted on a silhouette of...

Fabrication Tidbit #4: Making Tactile Reliefs
High-Quality Tactile Paintings The aim of this work is to bring the cultural heritage of two-dimensional art closer to being accessible by blind and visually impaired people. We present a computer-assisted workflow for the creation of tactile representations of paintings, suitable to be used as a learning tool in the context of guided tours in...
Fabrication Tidbit #2:
Band Decomposition of 2-Manifold Meshes For Physical Construction of Large Structures With the design and construction of more and more unusually shaped buildings, the computer graphics community has started to explore new methods to reduce the cost of the physical construction for large shapes. Most of currently suggested methods focus on reduction of the...
Rhinocam Training Manual from Mecsoft
www.mecsoft.com/guest/Training/TrainingManual-RhinoCAM.pdf I’ve been looking for something like this for the longest time and I stumbled upon on it today looking for something else. This makes me quite happy that there actually is official documentation for RhinoCam. Its a little lengthy but it explains most of the bizarre things in RhinoCam that aren’t the most intuitive...
Fabrication Tidbit #1: Digital Bas-Relief from 3D Scenes We present a system for semi-automatic creation of bas-relief sculpture. As an artistic medium, relief spans the continuum between 2D drawing or painting and full 3D sculpture. Bas-relief (or low relief) presents the unique challenge of squeezing shapes into a nearly-flat surface while maintaining as much as...
