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 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:
Using Inkscape to design your own laser cut product from scratch
Welcome to the third instalment of Ponoko’s back-to basics tutorials. This time we get creative and generate a laser cut design from scratch that can be used with your Ponoko Personal Factory.
It all begins with key information from the Inkscape Starter Kit, a tremendously useful resource that sorts out everything you need to know about the free software package, Inkscape.
The tutorial walks through how to use Inkscape to draw a design using basic shape tools, the text tool, and Path commands. In the demonstration, Josh whips up a laser cut coaster and repeats the pattern before finalising the file to be ready for laser cutting.
In a little over ten minutes, you’ll be able to:
• Create a design from scratch with Inkscape
• Create and combine basic shapes
• Check your design in outline mode
• Format your design for laser cutting
Stay tuned for Ponoko’s Laser Cutting Tutorial Part 4 where we get to see the laser work its magic.
iPad app makes it even easier to design for laser cutting
When we first heard about the iPad app Sketch It Make It, we were pretty excited. Now that developers Blank Slate Systems have released their clever drawing app to the public, our fingers are really twitching!
Sketch It Make It is able to rapidly transform even the wobbliest scribbles into neat geometric forms, and have them ready to export for digital manufacturing almost instantly. Whether you are laser cutting, using CNC milling or 3D printing there has quite possibly never been a faster way to turn ideas into tangible objects.
Using free design software to customize a design file
For the second instalment of Ponoko’s back-to-basics tutorials, we walk through the process of customizing a design file using freely available design software. The recommended software is called Inkscape, an open-source vector drawing program that offers powerful features in an easy-to-learn format.
Making use of the same free design file introduced in part 1 of the Laser Cutting Tutorial series, this time we walk through the process of adding your own text to the laser cut coaster.
Follow through as the process is explained from downloading Inkscape through to preparing the custom file for uploading to your Personal Factory.
In just under six minutes, you will know how to:
• Download Inkscape (available for Mac or PC)
• Open a design file in Inkscape
• Customize the design file with your own text
• Prepare the file for laser cutting
Now we’re just about ready to generate custom designs from scratch using Inkscape, so stay tuned for our Laser Cutting Tutorial Part 3.
Surplus store discovery inspires DIY mechanical marvel
Rope braiding machines are mesmerising to watch as they go through their mysterious machinations. Having spotted such a machine in a Surplus store, David from Mixed Media Engineering reverse-engineered the 1890’s product so that he could nut out exactly how the device works.
The result is a 16-bobbin laser cut wonder, with orbiting spools that guide the individual threads into an intricately woven mesh.
“I have been experimenting with some exotics such as carbon fiber yarns (rocket fusalage) embroidery thread for great braclets, surgical tube core with nylon shieth for pressure tubing, and para-cord nylon.”
There has been such a great response to the project that plans are in the works to turn it into a DIY kit on Kickstarter for others to enjoy. To catch a glimpse of those cogs in action, check out the brief clip of David introducing the rope braider at the source article.
In this back-to-basics tutorial video, we walk through the process of making a set of laser cut coasters from a free design file.
Following these steps is a great way to get started with Ponoko and realise what’s possible using your own Personal Factory.
In a few short minutes, you will know how to:
• Download a free design file • Add it to your Personal Factory • Choose material options to get personal pricing • Place an order
We’ve made it really easy to start making and get a feel for the laser cutting process. Stay tuned for future posts in this back-to-basics series as you work towards generating your own custom designs and becoming a successful digital maker.
A quicker, cheaper alternative to raster fill engraving
Vector or Raster? It’s a question that has goes back to the earliest days of laser etching. Here is an interesting little exploration from the creative team over at Cuddleburrito that scores another point for the Vector camp.
Instead of using a raster fill for a job that required large graphic elements, they devised a way to create the same effect using vector paths.
This saves a huge amount of time, as the laser only needs to engrave the actual paths of the lines instead of sweeping across the entire area. There was an added bonus that the outcome has a more consistent appearance when applied on timber, because the tendency for grain variation to be emphasized (as when using raster etching) had been eliminated.
