How to Use the 3D Printer STEP 1: Design Your 3D Part on a CAD
How to use the 3D Printer STEP 1: Design your 3D part on a CAD software What is it CAD Software? CAD (computer-aided design) software allows you to create 3D objects to print. Where can I get CAD Software? SolidWorks is a professional CAD software available free for SDSU students. Download SolidWorks at: http://engineering.sdsu.edu/support/ If you are a beginner, you can create 3D models using simple free software online. Among the most popular are: Google Sketchup, Wings 3D, Blender, and Sculptris. Optional step only if you are printing more than one part at a time? If you are printing more than one part you need to designate where you want the part printed on the printable platform. 1. Download and install the Makerbot Makerware Software found at http://www.makerbot.com/makerware/ 2. Open the MakerWare 3. Click “Add” to upload each of your parts. Upload the original file format (e.g. SolidWorks file format), not an .stl file 4. Move your parts until they are located in the desired spot. 5. Click “Make” to save your parts as an .stl file 6. Skip to STEP 3 STEP 2: Save your part as an stl. file using your CAD software. What is an .stl file? An .stl file is a language that 3D printers can read. If you try to print a SolidWorks or Google Sketchup file the 3D printer will not recognize it. STEP 3: Insert your .stl file on the 3D printer SD Card. The SD Card is plugged in near the control panel of the 3D Printer. -
Cultures of Sharing in 3D Printing: What Can We Learn from the Licence Choices of Thingiverse Users?
Cultures of sharing in 3D printing: what can we learn from the licence choices of Thingiverse users? 1. Introduction A growing literature in economics and social science has explored the practices of information exchange among online communities. A strong theme within this literature is that open cultures – characterised by reciprocal sharing, weak IP, and open flows of information among practitioners – are conducive to technological innovation. In Benkler’s influential analysis, the end result is “a flourishing nonmarket sector of information, knowledge, and cultural production… subject to an increasingly robust ethic of open sharing, open for all others to build on, extend, and make their own” (2006, p.7). This phenomenon has been the focus of much recent research on collaborative production models, covering a range of topics including wikis, open- access publishing, free software and open science (e.g. Nielson 2011, Suber 2012, Anderson 2012, Hatch 2013, Phelps 2013). One lesson from this literature is that sharing practices are context-dependent. Sharing is a social practice shaped by a range of variables, and sharing practices differ from community to community and from technology to technology (Kennedy 2013). Infrastructural issues, cultural factors and legal frameworks, both explicit and implicit, play a role in shaping the context in which collaboration occurs. It is therefore necessary to understand the norms, values, structures and systems that emerge around particular forms of practice. Scholars in various disciplines have taken up this challenge by documenting the specific (rather than universal) aspects of sharing practice, such as the regulatory frameworks that govern conduct and the variable properties of technological platforms (e.g. -

INTRODUCTION An aspiration of scientists and inventors, a darling of ‘Trekkies,’ Star Trek’s replicator is one of television’s great fictional ideas. First appearing in the late 1980s on Star Trek: The Next Generation, the replicator was a fictional device that could reproduce any food, liquid, or object its user wanted.1 Twenty years ago, the technology to create a tool out of thin air to fix a space station seemed like a possibility only on the silver screen. Today, the possibility of Star Trek’s replicator doesn’t seem so distant. In fact, NASA plans to roll out the first attempt at approaching the wonders of that technology for use on the final frontier in the near future.2 Once thought to be a science fiction fantasy, the ability to replicate models, prototypes, and ideas with a press of a button is now a reality. Three-dimensional (“3D”) printing has the potential to revolutionize the modern industry. -

Artur talks with Digital Art Live about his love of the ocean, his philosophy of beauty, and the techniques he uses to make his pictures. Picture: “The Sentinels” 12 ARTUR ROSA PORTUGAL VUE | PHOTOSHOP | POSER | ZBRUSH WEB DAL: Artur, welcome back to Digital Art Live magazine. We last interviewed you in our special #50 issue of the old 3D Art Direct magazine. That was back in early 2015, when we mainly focussed on your architectural series “White- Orange World” and your forest pictures. In this ‘Future Oceans’ themed issue of Digital Art Live we’d like to focus on some of your many ocean colony pictures and your recent sea view and sea -cave pictures. Which are superb, by the way! Some of the very best Vue work I’ve seen. Your recent work of the last six months is outstanding, even more so that the work you made in the early and mid 2010s. You must be very pleased at the level of achievement that you can now reach by using Vue and Photoshop? AR: Thank you for having me again, and thank you for the compliment and feedback. I’m humbled and honoured that my work may be of interest for your readers. To be honest, I’m never quite sure if my work is getting better or worse. -
