Half-tone CNC Reliefs

Half-tone CNC Reliefs

Images from Self-Occlusion We propose a complete system for designing, simulating, and fabricating surfaces with shading due to self-occlusion that induce desired input images. Our work is based on a simple observation. Consider a cylindrical hole (a pit) in a planar surface. As the depth of the hole increases, the...

Fabrication Tidbit #3: Laser Origami

Pepakura + LaserCutter + 3D printer = laserOrigami  This system uses an elevated piece of material in the bed of a normal laser cutter. It cuts and heats to folds until it is in the desired form. Then the piece comes out already assembled.

Printed Circuit Boards (PCBs) on the CNC Router

There are numerous ways to make printed circuit boards by applying a printed mask and etching them in a chemical like ferric chloride, but using the router can save a lot of time once you get over the learning curve and find the correct parameters. Additionally, you can mill the...

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 #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...
