Laser Cut Helical Springs

Coils that run rings around Slinky

Thanks to the addition of a rotary attachment for his laser cutter, Adam Watters has spent several months exploring what happens when you cut helical paths onto cylinders.

The variety of outcomes shows that there is a whole lot further to go with Springs than the trusty old Slinky would have us believe. Working in materials including acrylic, cardboard and 3d printed PLA, he has created a range of forms that have a mathematical beauty both as static objects and when in motion.

Discovering new patterns and the shapes and forms that follow has been a rewarding process for Adam. When questioned as to what the point of it all is, he had this to say:

For a little while, I turned my attention to finding an application for these, but that proved to be way less fun than experimenting with the process and cutting new springs. So for now, they are what they are.

Head over to Instructables where you can read all about laser cutting acrylic and cardboard springs, from a straightforward spiral through to cuboid grids, nested coils and even compression springs that take things in another direction entirely.

Laser Cut Turbine Whistle

Shrinking an air-raid siren to fit into your pocket

Quoted as being ideally suited for those looking to be really annoying, this laser cut project by Mark Langford on Instructables might catch your attention. Taking the same principles that give air-raid sirens such an impressive audio impact, he has condensed them down into a neat little package that can fit on a key ring.

After several iterations, the mechanics of the three-layer design were perfected and (as you can hear in the following video) it really does work. Extra points of course go to the fancy eyebrow acrobatics!

Here is how it works:

The air you blow in blows out through the pattern of holes, and at the same time, it makes the turbine spin.

If there was no turbine, the air would just hiss out of the holes, but the holes and blades are designed so that the spinning turbine alternately covers and uncovers the holes, rapidly blocking and releasing the air in a series of pulses that make the noise you hear.

See the Turbine Whistle on Instructables where you can learn from Mark’s thorough project walkthrough. There are plenty of step-by-step photos and of course you can download the files to make a pocket siren of your own.

Top 10 Designers Announced in Premium Materials Design Challenge

Vote for your Favorites by Sept 1st!

In July, we challenged designers to showcase their skills by creating a product using one of our three new premium materials. At first, we weren’t sure what to expect; This was the first time we ran a contest where designers actually created something tangible to enter, as opposed to just submitting their design files.

Would we get any good entries? Would folks just take the free sheet of material and run? We didn’t know.

We were thrilled to find that although the amount of submissions were somewhat smaller, the quality of entries we recieved were through the roof. The creativity & quality of the submissions made selecting the finalists a challenge in itself.

You can use the hashtag #ponokonewmaterials on Twitter, Facebook & Instagram to see all of the amazing submissions.

Check out the finalists below, and use the survey at the bottom of the page to vote for your top three before Sept 1st.

If you are the designer behind one of the final entries you are encouraged to invite all your friends and family to vote for you. Keep in mind: Voting ends at 10pm PST on Sept 1st.

The Prizes:

  • Grand Prize – $600 worth of making with your Personal Factory + free Prime for one year ($1,068 value.)

Laser Cut Typographic Gears

Round and round she goes, and where she stops, nobody knows

Check out this gem of a project from Mario Klingemann, otherwise known as Quasimondo. A few years back he whipped up a Typographic Gear Generator that is able to create pairs of wheels that interlock with mesmerising precision.

The gears can then be laser cut and added to your next mechanical marvel for all to enjoy. There is something whimsical and kind of cute about bundling in this extra layer to an otherwise run-of-the-mill laser cut component.

Pictured here (and in the following clip) is a laser cut geared wheel turning around a quote from the 1950’s tv classic, The Original Amateur Hour. Other variations that Mario has tried out include a Muybridge-inspired horse in motion, demonstrating that the process works just as well with images as it does with text.

Ponoko Customer Blows Past Kickstarter Goal in One Day


Brad Hill is the creator behind LittleRP – A DLP projector-based resin printer that can be put together for as little as $499.

Brad set out to create a printer that was open, flexible and affordable. Rather than using proprietary resins, the LittleRP is designed to use as many different formulations of UV curing resins as possible. By focusing on smaller, higher quality prints, the LittleRP is able to provide high accuracy while keeping costs low.

The flexibility and low cost helps explain the explosive popularity of the LittleRP’s Kickstarter, which passed it’s funding goal of $25,000 is under 24 hours. As of this writing the LittleRP has raised over $98,000, just under 400% of it’s original goal!

The LittleRP’s sleek translucent enclosure is made from Ponoko’s Acrylic Orange Tint, and the housing is made from Melamine Finished MDF seen here:

The LittleRP works using a process known as 3D stereolithography, a 3D printing process that uses light-sensitive resin and a high intensity light source to build a 3D object, layer by layer, rather than using spools of plastic filament as on a majority of 3D printers currently on the market. You can check out the LittleRP in action on it’s Kickstarter Video:
