3D Printing Basics

3D Printing Basics
Table of contents: 1. What is 3D printing? 3D printing is also known as desktop fabrication or additive manufacturing. It is a prototyping process whereby a real object is created from a 3D design. 2. 3D printing technologies There are several different 3D printing technologies. SLS (selective laser sintering), FDM (fused deposition modeling) & SLA (stereolithograhpy) are the most widely used technologies for 3D printing. This video describes how laser-sintering processes melt fine powders, bit by bit, into 3D shapes. This video shows how FDM works. The video below explains the process of Stereolithography (SLA). Generally, the main considerations are speed, cost of the printed prototype, cost of the 3D printer, choice and cost of materials and color capabilities. 3. October 5, 2011 - Roland DG Corporation introduced the new iModela iM-01. Sep, 2011 - Vienna University of Technology, a smaller, lighter and cheaper printing device has now been developed.

Natural history Museum « The Paradigm Shifter Much has already been speculatively said about the revolution that will begin when 3D printing migrates from being a niche hobby to a mainstream practice. The commentaries discussing it often focus on the industrial and legal ramifications of this innovation being as it has every potential to sound the death knell of traditional industry, doing away with mass production and ushering in a host of political changes. It is undeniable that however wide the scope of uptake of 3D printing is that it will have massive repercussions that will echo throughout history much like the printing press before it. Although it is arguable that an unhealthy amount of the discussion of the potential of this technology has focussed on its predicted impacts on consumerism to the detriment of the other likely ramifications. To begin with I will attempt to offer the briefest and least jargon heavy explanation of the fundamental principles of 3D printing possible. This post not sponsored by Nike. Like this:

Tutorial 8 - Random Points On Surface Introduction The Result of this tutorial A nice possible option in Grasshopper is to use a random generator to add randomness to your design. In this tutorial we will create a grid on a Rhino surface and then randomly pick a predefined number of grid points. This is a more advanced tutorial and it is advised to make the tutorial 1, 2 and 3 first, before attempting this tutorial. The Design The Rhino surface Before we start building the grasshopper model we need to create our Rhino Surface. Step 1 - Creating the basic grid Create the basic grid The first step is to link the Rhino surface within our Grasshopper model. We need to set the surface. RMB on the surface » select “Set one Surface” and click on the Rhino surface To create the grid on the surface we will divide the surface. We want to be able to change the number of divisions in order to change the number of grid points on the surface. Our grasshopper model should now look something like the image on the right. Looking at the list values

He made a second pass, capturing different angles and more detail. ”I want to see surfaces from three different directions to get the full articulation of the surface.”

Met 3-D: The Museum's First 3-D Scanning and Printing Hackathon Jackie Terrassa, Managing Museum Educator for Gallery and Studio Programs, Education; and Don Undeen, Senior Manager of Media Lab, Digital Media Posted: Thursday, May 31, 2012 «Artists come to the Met every day to be inspired, discovering visual and technical solutions in works from every corner of the world, ranging from ancient times to the present day. They might attend a program, sketch from objects, or create their own copies of original paintings, as they have done since 1872 when the Met first allowed artists to re-create works of art on display.» In that spirit, for the first time ever, on June 1 and 2, approximately twenty-five digital artists and programmers will gather at the Met to experiment with the latest 3D scanning and replicating technologies. Their aim will be to use the Museum's vast encyclopedic collections as a departure point for the creation of new work. "Printing" an image in 3D has been possible for some time.

Smithsonian turns to 3D to bring collection to the world | Geek Gestalt With just 2 percent of the Smithsonian's archive of 137 million items available to the public at any one time, an effort is under way at the world's largest museum and research institution to adopt 3D tools to expand its reach around the country. CNET has learned that the Smithsonian has a new initiative to create a series of 3D-printed models, exhibits, and scientific replicas--as well as to generate a new digital archive of 3D models of many of the physical objects in its collection. Representative of that effort, the museum is touting the 3D printed replica of a Thomas Jefferson statue that it recently installed for the "Slavery at Jefferson's Monticello: Paradox of Liberty" exhibit at the National Museum of African American History and Culture. According to the museum, this is the "largest 3D printed museum quality historical replica" on Earth and is a copy of a statue on display at Monticello, the Thomas Jefferson museum in Virginia. The only problem? Still, their goal is noble.

Teaching with a 3D Simulacrum When Shelley and David brought up the idea of 3D printing, my not-so-inner tech geek and my really-blatantly-outer education geek got pretty excited. As Shelley mentioned in her previous post, 3D printing is a hot topic in the museum world right now, with some exciting experimentation happening around the world. Just this week I was at a meeting at the American Museum of Natural History, hearing about some of the exciting 3D printing projects they’re working on with some of their teen programs. In our use it made sense to start with the Sensory Tour, our monthly tour for visitors with visual impairments as well as anyone who wants to experience art using more than just their sense of sight. We continually had great success using raised line drawings (they’re just what they sound like; the lines are literally raised from the surface of the paper) to help people feel contours of two-dimensional art. Why not try the same thing with one more dimension in the mix?

3D Printing for Accessibility In the last year, we’ve seen a lot happening in the museum space with 3D printing. The Smithsonian is working on what looks like a enormous project, the Met has a ongoing series of initiatives that look pretty cool, the San Francisco Asian Art Museum has hosted a “scanathon,” and the Art Institute of Chicago has been actively working in the space—just a handful of current projects going on. As part of an internal program within the Technology department, we’ve started a series of developer led R&D projects; developers propose what they want to experiment with and we set aside time in our busy work week to foster that creativity. In our first round of experiments David Huerta wanted to work with 3D printing; he’s incredibly passionate about this and has been following the 3D printing projects in the industry and beyond.

Capturing a Dinosaur: Using Digital Tools to Reproduce a Physical Model | Moosha Moosha Mooshme When I first visited the library at the AMNH, I was amazed by all of the physical items in the collection. As a public library, I expected to find books and publications on file, with the special Natural History and AMNH twist thrown in – original wonder cabinet catalogs, written log notes of old explorers, and such. But I was unprepared for the incredible art and memorabilia from across the history of the institution, and its potential for digitization. One of the first items to catch my eye was a nearly 100-year old concrete model of a Camarasaurus (the associated signage reads “Erwin S. In the spirit of full honesty, I have to admit this was our second attempt. This time, however, we could learn from our past mistakes. We did it twice, and only one of the captures worked, but it worked perfectly. The problem, we soon realized, was the head. Btw, here’s a Vine I made capturing the reflection of the overhead lights on the wall shining through the model as it was being printed:

» 3D Printer Finger Painting at Maker Faire Hot Pop Factory – 3D Printed Jewelry We had such a blast at this year’s Toronto Mini Maker Faire! For this special weekend event, we revisited one of our favorite childhood activities, finger painting, and updated it to our digital age with a Leap Motion, some 3D printers (of course) and a little bit of home-made code. The result, is the 3D Printer Finger Painting booth! Over the course of two days, we watched the bewildered faces of hundreds of kids, parents, grandparents and friends as they waved their fingers over the Leap Motion micro sensor, and saw their doodles instantly appear on a digital monitor. INSPIRATION We are passionate about finding the creative applications of 3D printing. WHY FINGER PAINTING? HARDWARE + SOFTWARE We used the Leap Motion, Makerbot Replicator 3D Printers and a couple of regular old desktop computers. HIGHLIGHTS The response at Maker Faire was fantastic!
