In the first episode of Shapeways Ask An Engineer we look at the strength of 3D printed wires at different thicknesses to better understand how to design for 3D printing.
Using a spring of the same size 3D printed in Nylon (WSF) using selective laser sintering, we look at the difference in strength and memory (bounce) of wires at 0.9, 1.0, 1.2, 1.5 and 2.0 mm. By understanding how much stress the material can take at different thicknesses you can design your parts to be much stronger with a very small increase in thickness. A wire 3D printed at 0.9mm has almost no memory, meaning it compresses under its own weight and is fairly fragile compared to a wire at 1.2mm (and additional 0.3mm or 0.01 of an inch) is much stronger and has considerable memory. As you can see in the video, at 2.0mm thickness (0.078 inch) the 3D printed Nylon is VERY strong, has great memory and flexibility.
If you have any 3D printing questions you would like answered by our 3D printing engineer Matthew Hagan please email askanengineer(at)shapeways(dot)com
This is an extremely helpful paper for those creating works that lie between sculptural and functional works and copyright does not cover functional objects but can in some cases cover aesthetic aspects of the functional objects. What we like to call, 'the grey area'. With this distinction the paper also clarifies a really important point which has been confusing for many people, a Creative Commons license cannot be used to legally protect a functional object. We have seen many people share their functional 3D files with a Creative Commons license in a number of places online, although this is not legally binding, it does offer a social construct that should be respected, a way to communicate the way in which you would like to share, and a possible framework for the future.
Take the time to read the paper, it is an incredibly useful resource for all of us navigating through unchartered waters.
The paper is shared under a Creative Commons license, of course... Great work by Michael Weinberg and his team.
Jessica of Nervous System has been busy experimenting with full color 3D printing. It's a bold new move for the design duo, who usually design in nylon and metals. Each print is 4 to 6 inches, the meshes are generated by Processing and 3D-printed by Shapeways. She must have been inspired by her coral-filled fish tank because these gorgeous "Colony" prints remind me of diving in the Caribbean. More eye candy on her Flickr set!
Shapeways is partnering with Ace Hotel New York during Fall Fashion Week! Haute. On February 9th, we'll be hosting an interactive event in Ace lobby that will explore how digital technology can revolutionize the future of fashion. Ace will also be hosting a Fashion Week lecture series on technology and fashion for design students.Participating designers include Ten Thousand Things, Ursa Major, Verameat, In God We Trust, Lindsey Adelman, Anna Sheffield and Chris Habana working with CAD modelers Kostika Spaho, Duann Scott and more.
This weeks Designer Spotlight focuses on Chris and Megan of Seedling Design. The pair is interested in mixing 3D printing with traditional materials like wood, ceramics, magnets and textiles, to create playful designs that invite wonder.
Tell us a little bit about yourself: Who are you? Where are you located?
Chris Schmidt and Megan Ender are Seedling Design. We have created jewelry and art for over 10 years and currently work out of our home studio in Oakland, CA. By day Chris is an industrial designer and invents toys for companies such as Mattel, Hasbro, Fisher-Price, MGA and LeapFrog. Megan has a career in non-profit work and art education. We design bold and unique pieces that attract attention and our wish is that you enjoy, get complimented and feel especially delightful wearing our products!
What's the story behind your designs? What inspires you?
Seedling Design stems from the concept of taking a seed of an idea and seeing how we can transform it into something magical. Some concepts we’ve started off with are: Imaginary rock collections, magnetic sculptures, food as jewelry, cool geometry, tensegrity, planet inspired jewelry, self-defense rings, what would our favorite artist’s jewelry look like, textiles with 3D printing, and other mixed media pieces. Inspiration comes from our everyday lives, our childhoods, nature and our interest in geometry, science and technology. We have a list of 200 ideas that keeps growing, including ideas such as how to bring back pop-beads for kids in a modern form.
What brought you to 3D printing with Shapeways?
In working in the design field for 15 years, Chris has seen the growth of 3D printing and was excited to use the technology. At work Chris uses an FDM (fused deposition modeling) printer all the time, but the output is less than attractive. Any other technology was always too expensive up until we discovered Shapeways. Now we can experiment all we want at a minimal cost.
How did you learn how to design in 3D?
When Chris was 15, he downloaded a copy of 3D studio and began to tinker. He went through several other 3D programs such as Animation Master, Truespace, Alias and finally discovered Rhino 3D, which he’s been using for the past 15 years.
How do you promote your work?
Since we are just starting out as a part-time, just for fun company, we’re only in the beginning phases of promoting our work. We started on Etsy and we are experimenting selling our work in several local Oakland shops. Since we both have fulltime jobs, getting ourselves out there has been a slow but informative process and we hope to keep expanding our audience.
Who are your favorite designers or artists? Who in the Shapeways community has served as an inspiration to you?
Our favorite artists and designers include: Tara Donovan, Gaudi, Anish Kapoor, Alexander Calder, Buckminster Fuller, Herbert Bayer, Louise Nevelson, Olafur Eliasson, Barbara Hepworth, Gabriel Orozco, Ai Weiwei, Shepard Fairey, Eva Hess and probably 50 more. As far as 3D printing artists, we’ve always liked the work of Nervous System and Bathsheba.
If you weren't limited by current technologies, what would you want to make using 3D printing?
Everything! Clothing, architecture, toys, but probably not food since we love our California produce
Nokia have made the rear shell for the Nokia Lumia 820 available to download from their developer site as an STL that can be uploaded and 3D printed by Shapeways or a STEP file that can be opened and parametrically modified by a variety of CAD software such as Solidworks and Inventor.
The Nokia Lumia 820 has a simple clip-on interchangeable back which makes it possible for people to change the color of their phone. By releasing the CAD file, people can now download and modify the basic design to add any feature they like, be it a functional like a folding stand, bike mount, cable wrap, or something cosmetic like branding, images or patterns.
What makes this really important is that a major manufacturer is making it possible for their customers to add value to their products without any cost to the manufacturer.
One thing to note is that the 3D file is quite fine, and will not suit all forms of 3D printing. We have uploaded the part to Shapeways and made it available for download. We are also doing some test prints at Shapeways this weekend to ensure printability in Nylon (WSF), but we do not recommend 3D printing components such as this in Acrylic as it may be too brittle and Nokia recommend no steel, ceramic or sandstone parts.
The file may also be challenging for Desktop FDM machines as the wall thickness and direction of the stresses may make this a fragile part.
The project in collaboration with Softlab, Sosolimited and Sticky Monster Lab accesses your Facebook profile to create a visualization of your interaction with family and friends, your likes and sharing patterns, so you can see yourself as others might see you, abstracted though the lens of the three artists and their applications.
We have been working on an exciting new feature for Shapeways.com: adding photographs to your model comments. You'll be able to share YOUR copy of a model that you ordered and show how you use it, how it looks in your home, how you painted it, even point out possible improvements and suggestions to the designer.
I talked to Brad Dickason, our VP of Product and the initiator of this new function. Brad says:
"There are tons of products that have been purchased on Shapeways and used in unique and innovative ways by our community. I'm ridiculously excited to see those photos start to show up so the designer can see how his/her products are being used and loved!"
You may notice these photo comments starting to appear today, as we've been busy testing them. But now it's your turn!
To attach a photo to a comment, simply click the camera icon and follow the prompts to upload your photo. You can even do it easily from your mobile device. We know you have some cool 3D printed products on your desk, so snap a pic and show the designer their work in the wild!
Lastly, just a little bit of fine print:
As with our general policy on comments and the forum, please use common sense when uploading photos, and keep them polite, relevant and constructive. We're not uptight, but we do need to make sure people feel comfortable. If you'd feel weird about your boss looking over your shoulder at whatever photo you're about to post, you probably shouldn't post it. For argument's sake, let's assume you've got a cool boss. That said, if you see something that offends you, hit the flag button and tell us why it offends you.
In my youth, when I was backpacking around the world I spent a few months in Seattle but I never got to see the peak of the Mt. Rainier until the day that I flew out of Tacoma airport, and there above the clouds was the peak of the mountain. It is an image burnt into my memory, of a time in my life of freedom and wonder.
Of course as time passes, memory fades and one forgets or exaggerates the past, so it is always nice to have a little something to hold the memory fast in one's mind. A postcard may act as a trigger, but it is so one dimensional, and could never capture 'that view'. Now TinyMtn comes to the rescue with, tiny 3D printed mountains. Now I can have Mt. Ranier 3D printed on my desktop, and when I want to reminisce, I can drop some dry ice in a glass of water for an impromptu cloud, pull out my iPhone with an Olloclip attachment and fly it around the mountain, peering into the screen just like I peered out of the window in awe of the mountain peak, so many years ago. Thank you TinyMtn...
If you've got an interest in 3D printing and can wrangle a 2D image
then we've got something for you to try!
On January 15th at 7pm at
Office Nomads in Seattle we'll be letting you play with the software, have some
drinks and discuss 3D printing.
If you'd like to run the software during the session then please
bring a laptop and some image software. We've been working with
Illustrator, Photoshop, Inkscape and Gimp so far. The software takes in
JPEG or PNG images. A good resolution to use 300 DPI images.
Jrey's wife is from the Bahamas so he designed a sea shell ring and set of earrings to remind her of home and had them 3D printed in Sterling Silver by Shapeways. The jewelry looks beautiful and she absolutely loved them. Now this is the only jewelry of it's kind in the entire world, made especially for one woman designed for her alone by her husband. This is the kind of gift that will be passed on for generations, with the grandmother telling the granddaughter the story of it's creation, and the depth of meaning that far exceeds any item bought off of the shelf.
As the field of 3D printing grows, we're starting to see more and more cases of copyright infringement, creative sharing, collaboration, and general discussion happening around what is "allowed", what is possible, and what is protected.
