The basics of home 3D printing in 2015

Reflections after 16 hours with a new 3D printer

As a spectator, it may appear like 3D printers are getting closer than ever to being as easy to use as a desktop inkjet printer. For those who have purchased (or indeed built) their own 3D printer over the last few years, you’d know that this is not the case. There is a lot of tweaking, upgrading and also patience required to get this amazing technology up and running in your own home.

Scott Hanselman plunged into the world of 3D printing and has published an hour-by-hour account of his first two days (16 hours of ‘working’ time) with the Printrbot printer. It’s an engaging tale of triumphs and woes, with much useful advice for others who may be wondering whether to purchase a printer of their own in the near future.

I’ve been using this printer now for basically 16 total hours over a few days, so we’ll call it two days. I went through a number of emotions over this last two days an learned a TON, some about the Printrbot Simple Metal specifically, but also about 3D Printing in general.

Click through to read the full account and discover why Scott’s concluding thoughts are positive and optimistic about the future of home 3D printing.

Bitsbox monthly projects for kids

How to nurture creativity for the digital makers of the future

For many of us, learning coding simply isn’t fun – but perhaps we’ve gone about it all wrong. Two former Google employees (who also happen to be Dads) saw a way to make learning coding languages fun for kids, and their solution has gathered quite a following on Kickstarter. They call their learning system Bitsbox, and as you’ll soon see, there is more to the bits than just what’s in the box.

We don’t teach our kids how to read and write so that they can be novelists. We teach them those skills so that they can be happy, so that they can be successful in whatever path they choose.

Bitsbox operates both online and as a subscription-based service that delivers boxes of coding projects in the mail to kids every month. Within minutes, kids are able to create apps that can run on a real device. The magic of the monthly deliveries is that they will keep kids hungry for more; and excited to engage with newer (and more challenging) projects as they become increasingly proficient with their coding skills.

What excites us at Ponoko is that these children will become the next generation of creative software designers and digital makers. This means that we can well and truly expect the 3D designers and laser cutting makers of the future to totally blow our minds.

Become a part of the Bitsbox community and make the most of the Kickstarter funding perks before the campaign closes.

Javascript Laser Cut Lamp Shades

A few lines of code to brighten your day

When Maxime Beauchemin set out to design a pair of laser cut lamp shades, he decided that it would be fun to make use of his coding skills. Already familiar with d3.js, he used Javascript to generate the vector artwork that would then be sent to the laser cutter.

This was much easier than it may otherwise appear thanks to the interactive setup at jsfiddle.net, a fantastic resource that some refer to as a ‘playground for developers’. Here is a screenshot of the number crunching that makes Maxime’s lamp possible:

This looks like an interesting way to approach design for laser cutting, with the interactive preview keeping the outcome right there on screen. Of course, a little coding knowledge would be handy to get started… but for those who just want to play, you can head over to jsfiddle and tweak Maxime’s code to make further iterations of his Javascript Laser Cut Lampshade.

Manufacturing The Future

How 3D printing went from pipe dream to your desktop

When Ponoko was founded back in 2006, we envisaged the third Industrial Revolution, where consumers of the future can download and make products at home. The road to distributed digital mass production was paved by the pioneering work of stereolithography inventor Chuck Hull and transformed once again with the rise and rise of MakerBot, to name just a few.

In a fantastically comprehensive article over on Digital Trends, the full history of 3D printing has been laid out in detail.

3D printers are all the rage with enthusiasts, but they didn’t just materialize out of nowhere like the sculptures they produce. Here’s the untold story of how the next big boom in technology came to be over 30 years.

It’s a fascinating story where dreams become reality and the stuff of science fiction enters our daily lives. We have seen this first-hand, with over 400,000 custom products produced online via Ponoko’s global network of digital making services.

Click through to Digital Trends to learn how other key influencers have helped shape the strange past and seemingly impossible future of distributed digital mass production over the past 30 years.

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:

Want to get your hands on your own LittleRP? Head over to Brad’s Kickstarter page to get one while you still can.

Open Source Laser Cut CT Scanner

Taking a DIY approach to high tech imaging

Providing the magical ability to scan not only the surface, but also to reveal details of the insides of an object, the CT (computed tomography) scanner has quite literally changed the way we see ourselves.

Modern CT scanners are frightfully expensive and are usually found in hospitals but Canadian-born Peter Jansen has built one himself out of laser cut wood.

“After seeing the cost for my CT scan, I decided it was time to try to build an open source desktop CT scanner for small objects, and to do it for much less than the cost of a single scan.”

With a design quite similar to the early commercial CT scanners, Peter’s device began as a quarter-scale laser cut acrylic version that he whipped up in a single day.

He then used this mockup to help refine the design, under the watchful gaze of a friendly house cat. (more…)

DIY Kerf measuring tool refines your laser cutting precision

Although it isn’t critical on all laser cut projects, for anything with parts that fit or slot together, kerf is something that is worth paying attention to.

It may sound like a Jim Henson creation – but kerf is in fact a very real technical term. Kerf refers to the gap that is left by the cutting device – in our case, the laser beam in a laser cutter. It’s usually more of an issue when laser cutting in wood, but will also come into play when laser cutting acrylic and other materials.

Open source enthusiast Dave Chamberlin has come up with a nifty device that can be used to accurately measure the kerf of a laser cutter. The simple cutting pattern has been uploaded to Thingiverse, and includes instructions on how to measure your kerf etched right onto the device itself. Here is what it looks like:

Follow the source link below to download the file and try it out on your own laser cutter. You can also discover what else Dave is up to in his open source maker crusade over at Takeaway 3d Tech.

Exploded hardware wall art

Creative inspiration as products are exposed in all their glory

We all know the story… the kids who spend hours pulling apart every product they can get their hands on will grow up to become tomorrow’s designers, engineers and creative geniuses. Well, the offices of Bolt in downtown Boston show that this is more than just a cliché.

Building a great hardware product is brutally hard work and our walls remind us of that everyday.

Set with a relatively small budget for decorating the office space in an inspirational way, the Bolt team made a list of their favourite hardware products of all time and purchased each item from eBay. The products were then disassembled, cleaned, and mounted on the walls in all their exploded designer glory.

This can be seen as merely an ‘art project’, with all the innards of the products exposed and neatly knolled into place. But as the exposed products become more and more a part of the every day, they have become valuable tools to educate, inspire and remind of how important exquisite design and meticulous engineering are to the success of a business.   (more…)
