  • Before purchasing your printer, take a moment to think about how it will benefit you. Although you will, no doubt, find things that you will do with your printer that you would never have anticipated, you should feel confident that you have enough print needs that the printer is worth the initial investment.
  • As a beginner in the world of 3D printing, you are going to want to have plenty of support. Purchasing your printer from a knowledgeable team who will happily offer their assistance, such as The 3D Printer’s Guild, means that you will be left with fewer headaches as you learn to navigate your printer and design software.
  • Familiarize yourself with the policies of the manufacturer. Check to see what sort of warranties and protection plans are offered. If you run into any issues with your machine, you want to be sure that you are protected.
  • Check out some online resources. Forums, blogs, and reviews are fantastic ways to find out more about individual printers, design software, and materials. They are also full of great tips and tricks to help you customize your printer settings to get the exact effect that you are looking for.
  • Before you purchase your machine, do a little research on 3D modeling. There are great websites available, such as Thingiverse, that offer designs that you can either download for free or for a small fee. As you learn about the basics of 3D printing, these pre-designed models are a great option. When you begin to feel more comfortable with your machine, however, you are going to want to start customizing your own parts. Start with a free design program, such as Autodesk’s 123D Design (Learn what happened to 123Dapp), for a simple way to start designing your own prints. Alternatively you can use Autodesk’s Fusion 360 for your design work.
  • To really know if a 3D printer is for you, you may want to see it in action. Industry shows and Maker Faires are great options. Meetups with 3D printing groups are another valuable source of information. If you live in the Western North Carolina region, for example, join us at one of our upcoming 3D Printer’s Guild Meetups.
  • When deciding between machines, a 3D printing hub can be quite helpful. Simply order the same model to be printed by two machines you are deciding between to see which best meets your specifications.
  • As with any online reviews, remember to take the 3D printer reviews with a grain of salt. For starters, people are much more likely to write an angry review about an unpleasant experience than they are to write a good review about a pleasant experience. Furthermore, reviews in magazines are often written after a small time spent with the machine. Since it can take quite a while to become familiar with your machine and its unique settings, these articles may not tell the whole tale. Although reviews are one important part of your research process, don’t let them become unduly important in your search.

With these buying tips, you can feel confident making your 3D purchase. If you would like more information about buying your 3D printer, please feel free to contact us.

3D Printing and Copyright Law: The Case of the Penrose Triangle

3D Printing and Copyright Law: The Case of the Penrose Triangle

3D Printing and Copyright Law

With the development of 3D scanners and printers, anyone who has access to this technology can accurately reproduce objects found in the real world. This has many far-reaching implications, some of which could lead to greater innovation, others which could lead to a whole new host of problems. In this series, we will explore the copyright implications of 3D printing as designers, end users, and lawyers try to sort out the many legal implications of 3D printing and copyright law.

The Penrose Triangle

For the first installment, we will discuss the interesting case of Ulrich Schwanitz and The Penrose Triangle.
To get to the root of this tale, we have to go all the way back to 1934 when artist Oscar Reutersvard drew the first-known Penrose Triangle. Referred to as an “impossible figure,” the Penrose Triangle connects on each side at a right-angle. For decades, this optical illusion was confined to drawings on flat surface and was thought impossible to reproduce in 3D space.

That is, until Ulrich Schwanitz, a designer based out of the Netherlands, purportedly solved the problem. Rather than explaining how he solved the puzzle, Schwanitz simply included a YouTube video showing his design. The model was put up for sale on the Shapeways website for around $70.

Now, this is where it really gets interesting. Along came Artus Tchoukanov who had formerly been an intern at Shapeways. Tchoukanov was able to watch the above video and figure out how Schwanitz had created his design. Tchoukanov then went to Thingiverse, a 3D printing community that actively encourages the free and open interchange of design and ideas, and published his interpretation of Schwanitz’s solution.


Soon, a story about the mystery of the Penrose Triangle appeared, wrongly crediting Tchoukanov with being the first to arrive at a 3D solution. Schwanitz then responded by sending Thingiverse a DMCA (which stands for Digital Millennium Copyright ACT) Takedown notice, suggesting that the published Penrose Triangle solution was copyright infringement and that it should be removed from the site. Thingiverse promptly took the post down while explaining that it was the first such request that they had received.

Now that the first DMCA Takedown request has been handed out to a distributor of online 3D design content, it is possible that Schwanitz (who, by the way, allowed Thingiverse to put the post back up after he received a good amount of negative commentary over his request) has opened a whole can of legal worms. As 3D printers become more and more common and people are better able to produce their own parts and designs at home, these sorts of issues promise to be all the more prevalent.

Tell us what you think. If you were in Schwanitz’s position, how would you have handled the situation? How strictly do you think we should be policing copyright laws in regards to 3D print files?
