In a world where we can buy affordable 3d printers it can seem intimidating when it comes to creating your own 3D model for the first time. This is what the founders envisioned when they created their first successful Kickstarter for the Doodle 3d WiFi box with embeded sketch app (still available). For the first time you could not only use your fingers to paint a 2d sketch and extrude it into 3D you could send the design directly to your printer over USB. The WiFi box hosts an app that allows any touch interface like phones or tablets to be the modeling tool wirelessly. It’s much easier than it sounds.
The founders have improved upon the concept by releasing the Doodle3D Transform App, which runs a web technology-based app and forthcoming tablet app, pending a successful campaign. You can draw by hand, scan photos/drawings or import existing images. In addition to sending your design to your 3D-printer you can upload it to an online service like 3D Hubs for output, if you’re still saving up for a printer. But instead of being limited to single-walled prints you can create complex objects with the same simplicity of the original. Watch the video above and see all the capabilities on their campaign page.
The above image shows solids that all have the same volume, you can check this by filling one with water and then pouring that water into the next, fixed-volume objects. You can use the OpenSCAD script that Rich Cameron (aka Whosawhatsis) shared or download the sample objects. But why? Rich Cameron and Joan Horvarth, well-known authors, are on a mission to get all the 3d printers in the world, in all those new classrooms to help visually impaired students make use of 3D prints to learn just about any subject, but they need help making good models. This is where you come in.
Start off by downloading the sample objects above or generating your own via the openSCAD script we mentioned. Then visit the project page on Hackaday.io to get instructions on how you can volunteer to help this community and join their Google Group to continue the conversation. This is a great tactile to learn and a great way to share your talents with the world.
“Often students with visual impairments have difficulty with concepts based on visual/spatial relationships, particularly in math and science. 3D prints offer an unprecedented asset for their teachers, and 3D printers are becoming affordable. But these teachers need help designing models. [Whosawhastis] and I have been volunteer mentors to various groups working on figuring out the best ways to use 3D printing for the visually impaired. Our goal with this project is to document some simple, practical conventions for designing models, and lay the groundwork so that interested parties can create the needed designs. We know that schools have 3D printers and want to teach design thinking to their students. This project creates a minimalist open-source way to link teachers who need design files and (sighted) students who want projects to do. We want students to create the designs for the needed models, learning science, math and other subjects while helping their visually-impaired peers.”
DUS Architects in Amsterdam has created a tiny gabled urban cabin that is a mere 25 cubic metres (882.87 cubic feet) using FDM technology. They are allowing guests to spend the night to experience what life in a micro 3d printed home might be like. There is no toilet but you can take a bath outside au natural. Concrete set into the infill gives it strength and forms a seat on certain locations while pebbles in the infill outside form a path.

A window punctures one end, while the other integrates both an entrance and a stepped porch seating area. Its walls are patterned with angular protrusions that create a three-dimensional surface, giving the building extra structural stability.
It really is further insight into the groups design sensibility that is part of major project that launched in 2013, to be complete next year, a four story 3D printed canal house. They use the KamerMaker (Dutch for “room maker”) and KamerMaker2, a “XXL 3D Printer” 3.5 meters high and housed in an up-ended shipping container to produce the large pieces. They use bio-plastics on all pieces and say it is a part of a future ecosystem that allows full recycling of the material.

The amazing folks in the Tangible Media Group at MIT Media Lab have shared their research with creating the software to produce small hairs or Cilia from 150 to 50 micrometers to do things such as move, sense, adhere, or be aesthetically pleasing.
Looking into the Nature, hair has numerous functions such as to provide warmth, adhesion, locomotion, sensing, a sense of touch, as well as it’s well known aesthetic qualities. This work presents a computational method of 3D printing hair structures. It allows us to design and generate hair geometry at 50 micrometer resolution and assign various functionalities to the hair. The ability to fabricate customized hair structures enables us to create super fine surface texture; mechanical adhesion property; new passive actuators and touch sensors on a 3D printed artifact. We also present several applications to show how the 3D-printed hair can be used for designing everyday interactive objects.

ALFRED CLEBSCH Rudolf Friedrich Alfred Clebsch (19 January 1833—7 November 1872) was a German mathematician who worked with algebraic geometry and invariant theory. He collaborated with Paul Gordan on Clebsch—Gordan coefficients for spherical harmonics, which are now widely used in quantum mechanics.The Clebsch diagonal cubic surface, or Klein’s icosahedral cubic surface is a cubic surface is a well known form, all of whose 27 exceptional lines can be defined over the real numbers.
The production of food by machines is a fact of modern food production, from pasta, to Twinkies, to canned foods, raw ingredients are processed in factories all over the world. The only problem is each piece of food is identical, no customization or personalization is possible. Enter 3D Printing. If 3D Printing is considered being in infancy, then printing food is still in the womb. We now have so many tools at our disposal, open-source or not that it’s possible to print in sugar, chocolate, pasta, and more, just by replacing the standard toolhead with one that extrudes softer ingredient materials. Below are just a few of the projects that are growing in the food printing space with large photos to illustrate the yumminess of the prints…and failures! While it can seem like just a fun way to eat sweets on the surface, 3d printing food has ramifications that could help feed the worlds poor, provide elderly with nutrient-rich foods, or provide astronauts in space with a little more variety in a confined space than pouches of powder.

Digital Food | Columbia Engineering
The above video shows what the folks at Columbia University in NYC’s School of Engineering, under the direction of Mechanical Engineering Professor Hod Lipson think about printing food, even going as far as creating a machine that also cooks the food after printing it. Make sure to watch the behind the scenes video for more!
CandyFab
The first 3D printer I ever saw was actually a machine designed to create models from sugar. It used heated air to fuse a sugar bed layer into wondrous geometric shapes. It ultimately was not mass manufactured but at a time when desktop 3d printing machines were coming online in 2009, it was surely a creative influence on many. Read more about the CandyFab machine!

PrintrBot Printrbot, a well-respected 3d printer company, created a commercial paste extrusion system that can be added to their printers. This innovation has also lead to the below product collaborations, the Bocusini, and the Magic Candy Factory.
Bocusini Bocusini calls itself “…the world’s first Plug & Play Food Printing System” and hosts a myriad of recipes an ingredients in this turnkey system that comes with all the hardware and software you need to create your own edible art!
The Magic Candy Factory is indeed a magical place where people can not only buy candy but design and create their own custom piece of candy right in the store.
Discovery Extruder The Discovery Extruder is a very refined DIY paste extrusion system that can be retrofitted into any 3d printer, even as a second extruder. While is can indeed extrude exotic materials like silicone, it can also extrude materials like Nutella!
Ultimaker Syringe Extruder This printable open-source design gives you a paste extruder for things like nutella, peanut butter and chocolate. Like all of Joris’ designs it has a unique solution, it uses the filament itself as a cable to pull the stopper down and extrude whatever you load into the syringe.
Printing in 3 dimensions
Non-planar FDM (Fused Deposition Modeling) describes a printing process where layers are not deposited in uniform layers but rather in smooth, curved layers that allow creating smooth curved surfaces or features instead of the characteristic start-stepping from current FDM processes. Read more about the author’s tests for smooth, curved-surfaces, strength of such parts, structured surfaces and his hands-on tests that you can try for yourself. His method involves post-processing gcode via Slic3r. (Read Full Article via Hackaday)
We’ve seen experiments like this before from Joris who also post-processed gcode to produce beautiful structures and cups with curved tops. See his uploads to YouMagine and a sample video of one of these pieces being printed below.
