FaBrickation: Fast 3D printing of Functional Objects by Integrating Construction Kit Building Blocks. | Stefanie Mueller. An already printed object. As this allows for faster design iteration, it allows users to iterate more and thus ultimately leads to better designs . Back in the 3D editor Blender, the user extends the nosepiece so as to perfectly fit the user’s nose. After the user exits the edit mode in faBrickator aligns the current version of the 3D model with the previously printed one to minimize the number of bricks that need to be re-fabricated. Figure 9: (a,b) faBrickator highlights what changed between two model versions.
The main contribution of this paper is a novel approach to fast 3D fabrication and a system called faBrickator that implements this approach. Validation ). Functional objects, i.e., objects that have shape constraints only in specific areas, which is commonly the case for objects that fulfill a functional purpose. FaBrickator is built in CoffeeScript using the constructive solid geometry library for its geometry operations. Blender Plugin written in Python and faBrickator Our edit. Ice and chocolate molds with 3D printing. As always with 3D printing, you can not do anything without 3D model created by 3D modeling or 3D scanning - I use Rhinoceros for all of my modelings but you can use anything you like - there are bunch of free modeling tools out there so go and explore. One thing you need to take care of, when talking about 3D printing, is creating a so called "water tight model" or WTM. This WTM in plain words marks that your design should have no holes and "leaks" where water could came out if in theory you would fill it up.
You should not have objects without volume (plain surfaces or curves) - everything needs to be a solid so the printer can make it. The best way to make sure you have no errors (holes, overlapping triangles, bad edges, etc) which could affect quality of the print, is to use some of the specialized softwares for 3DP preparation - a good free solutions are MiniMagics and MeshLab.

NIH 3D Print Exchange | A collection of biomedical 3D printable files and 3D printing resources supported by the National Institutes of Health (NIH) Mini RC Blimp by zimirken. First, I purchased this micro RC car from amazon. I also purchased this vibrator motor from my local radio shack and removed the counterweight. The parts are printed with full infill of course. The shaft hole for the propeller will likely get filled in.
The printed propellers work fine, but I'm sure they could be replaced with superior purchased ones. In taking apart the car, I cut off the lights and the steering coil, and soldered the steering motor in place of the coil. Frame 2 is superglued to frame 1, and the switch and charging port are superglued to frame 2. A large straw is used to connect the steering motor frame 3 to frame 1. See the instructable for other details on the build. 3D Printed Protein | over-engineered. This post will demonstrate how to prepare a protein model to be 3D printed. This will result in a .STL file for home printing, or a full-color .OBJ file that can be printed using an online service such as Sculpteo. Requirements .PDB (Protein Databank) of the protein.
This entry uses a protein that my brother is researching.UCSF Chimera (version 1.8.1 is used below)MeshLab (version 1.3.2 is used below) Prepare the Model These steps will convert the .PDB file into a .OBJ file that can be printed. Printing Full Color Sandstone Upload the zip file to a 3D printing service (Sculpteo produced the model below) and follow their ordering process. This material can be fragile, so it is not the best for models with thin supports (such as this particular protein).

If you have an Ultimaker, upgrade to Cura 13.06 or newer! NOTE: It is a closed beta right now, so you will have to hunt for the link. I will not be posting it because of it's status. Alpha 1.8.1: - Resized form to fit smaller screens; the next major release will have a resizable form. Alpha 1.8: - Windows XP Support - Added Resolution Limiter - UI Improvements - New Anti-Spike Features Let me start by saying this is an Alpha! I saw a stamp maker the other day but it was Mac only (OmNomNom - and the author didnâ€™t want to translate it, so, I made one over the weekend!
I plan to add RGB control, a blur function, additional surface optimizations and an option to smooth high boarders (very useful in B/W [stamp] mode). Tell me what you think! Have fun! Rapid Prototyping Models --- George W. Hart. Background Rapid Prototyping or Solid Freeform Fabrication refers to a range of new technologies which construct physical three-dimensional objects by assembling thin layers of material under computer control. Objects can be made which are extremely accurate, complex, and beautiful, and which no other technology can produce.
For basic information on this rapidly evolving technology, I recommend this site or this site or search Google for new developments. Presently this is a somewhat expensive technology used mainly in high-end product design, and in research universities. But in the future, the cost will certainly come down and everyone will be able to create amazing physical objects with these machines.

Beginning Addition and Subtraction Manipulatives by happycamper. This is a set of math manipulatives I created for my daughter. They are commonly used in special education programs. (Popular in the UK, I believe.) For best results, print each number out in a different color (See example.) There are many commercial and freely available activities that can be used with this type of manipulative. Examples include: Commercial examples at: Free to download activities at: Oxford University Press MyBookEzzz.org Good for use as practice 3D printing objects the parts do not require any structural support. (The base is 5x5 since that is the maximum size for my printer...) **5x5 base now has pegs slightly smaller to allow a bit more "give" to placement of the manipulatives. 3D-Printed Biologically-Inspired Robotics.
I have been spending the last few months doing research into biologically inspired robotic structures. While my approach may seem formalistic in nature, these devices were simply a means for ultimately conducting social research. This desire stems from my experience building Simple Bots, and their subsequent display at multiple Maker Faires. While displaying these robots, I observed that the thousands of people who interacted with them, projected their own social realities upon these devices which were little more than motors zip tied to plastic household utensils.
The obvious shortcoming of the Simple Bots approach was that no matter what personalities people projected upon these creations, they ultimately implicitly understood that these creatures were robotic. This led me to wonder what would happen if I built robots that were more intentionally organic-like and fluid in motion. Tools. Infectious Pathogens by educator. The capsids and nucleocapsids of viruses are only nanometers across and protect the viral genome encased within ( The capsids are beautiful examples of icosahedral symmetry and are wonderful examples of self-assembly. Many nanotechnologists are now trying to replicate what nature does so well in order to deliver drugs more effectively among other things. In order to teach about virus structure and self-assembly, I took x-ray crystal structure data and models of various viruses from the VIPER database (.vdb files) ( and converted them to .stl files using the program, Chimera ( Instructions for converting models are below as well as a short description of each virus.
When slicing the viruses, there are some errors; however, the viruses print well. Any suggestions and improvement to the .stl files is appreciated. Hepatitis B, database # 2g33 Convert vdb to stl file Save as stl file.
