Solidry is new 3d model marketplace focused on Indian market

Solidry is new 3d model and 3d printing marketplace from India. They are the first such service based in India. There are many new online marketplaces, but community development is always critical. We will see how they develop in the future.
All you Indian readers, go and check them out.

Good luck Solidry!


Slic3r stable version 1.1.6 new features and review by James Bruton

Slic3r stable version 1.1.6 is out. Since last time I looked at it it now has many new options like linear gap fill, per-region settings, modifier meshes, pillars / bridge support material, model cutting etc.

Here is a review by James Bruton (known for his 3d printed costumes such as 3d printed Xenomorph). He
explains functions like improved multi-material print handling and others.


Wearable Arduino based display on 3d printed glasses frame made by 13 year old

13 year old Clay Haight made this sub-100$ dollar simple wearable eye display. There are many other DIY Google Glass projects that involve 3d printing, but non with such a young maker.

From the source:
Clay’s DIY “Google Glass” uses the sensors on the Arduino Esplora along with the Arduino LCD screen and a 3D printed frame.
He can use voice commands to bring up a calendar with his schedule, local maps, and temperature and weather info.
A headband on the back keeps it from tilting to one side.
“Now they are extremely comfortable,” says Clay. “In fact I wear them around my house and tell my parents the temperature just for fun!”

Lobo 3d printer developed by Jeff Kerr

Here is first look at Lobo 3D printer developed and built by Jeff Kerr. Jeff is known for his design of Feather non-cartesian 3d printer.
He will make plans for Lobo publicly available once he has finished the project. I'll follow his work and keep this post updated.
Nice work Jeff! Keep it going!

New video on custom leg prosthetic by 3D Systems: Making Natasha's 3D-Printed Prosthetic in Two Weeks

From video description:
When Natasha Hope-Simpson lost her leg, her life came to a stop. But she built new momentum through design, as she created a beautiful, custom 3D-printable prosthetic leg that reflected her character in ways that a stock prosthetic never could. See how she and a team of 3D experts went from design to prototype in only two weeks.

Cubespawn is developing modules for your home factory

CubeSpawn is an open source project with the mission to bring automated manufacturing to individuals and small business. It is an open source flexible manufacturing systems (FMS).
They want to develop several machine modules with different functions like 3d printer, laser cutter, saw, lathe, drill and mill which are connected by transport system or conveyor belt. You could make your house own micro factory.
The project is ambitious and I wish them success.

How to check your 3d models before printing and validate STL files

Here are two useful presentations on how to improve your prints with pre-print validations tools.

Here is presentation on basic parameters to check and four software tools; 3D-Tool, MeshLab, MiniMagics an NetFab.

This STL file validation guide is based on NetFab http://www.netfabb.com and it deals with several 3d model / STL file parameters like scale and dimension, object orientation, wall thickness and other various STL errors.

Erectorbot large volume 3d printer and Erectostruder pellet extruder

Erectorbot is new large volume DIY 3d printer developed by Leonard Dodd. Beside large volume it features exchangable heads for a CNC plasma cutter, router, and welder.

From EB1 homepage:
ErectorBot or EB1 is a large scale 3D printing full service gantry bot. Part of a series, our EB1 is the largest of the group. Just as in racing, we pushed the limits of precision and then bring this technology back down to size. So whether its our desktop model, 3ft x 2ft x 2ft or it’s one of the 3 larger models we offer.
You will enjoy TWICE the printable space (build area) in the same amount of space as you will find in the more conventional setups. This also allows us to treat the heat bed a little differently as well. No weight issues. Dynamics don’t change as your model grows. And neither should your wallet. The stationary bed design is modular and very low cost. And how about NOT HAVING to level the bed every model or run? We can choose our table to tip gap by extruder temp.

It will be priced at range of $11,500 to $35,000.

Erectostruder is pellet 3d printing exruder that can also be mounted on EB1 that can use different types of materials and be used as a filament extruder.

  • Runs even the small Nema 17 and powerful doing so.
  • Shift-able planetary gears (high -Low)
  • Easy clean up (4 thumb screws)
  • Extreme temp range – frozen slush to 300 C
  • Resolution – the smallest standard up to 2mm
  • Customization – steam punk ~ beer still- high tech (3 themes thus far)
  • Liquid Cool compatible
  • High volume hopper options – laser vac
  • Twin element for precise control
  • Two sized augers for different sized pellets.
  • Arduino micro kit (stand alone ) filament extruder mode. (Yes doubles as a filament machine.)
  • All metal main components, ultra light, TIG welded, hand crafted by a master metal modeler and serialized.
  • Quick mount/release.
  • Multi head compatible.


Hacking vintage Triumph TR3 car with 3d printing

In this video EpicenterBryan shows how he modified his vintage cars tail lights with a help of 3d printing to install LED lights for more safety. You can call it modifying but I call it hacking. Realistic and usable merger of new and old technology.  It is also an tribute to DIY culture and handcraft since there were no robots involved in production of this Triumph.

He writes:
Here is one of my many projects. I thought our YouTube subscribers might get a kick out of this one. Some of you might know that I'm into old British cars, and have been my entire life. They are stylish and sexy. They are quirky and failure prone. Early ones have such serious safety issues I'm surprised any of us ever survived driving them all these years.

The stock Triumph TR3 has only one center brake light and if it fails, people run into you. That is why most early cars have been tagged in the rear. The right and left tail lights are only used as runner lights and turn signals. I wanted a quick and easy way to add brake lighting before making a bunch of wiring changes to the car. In the near future I will be adding relays in the tail to convert the function of the bright element of the 1157 dual element bulb to be not only turn signals but also brake lights. I have already designed and printed the 3D parts needed to mount the relays and will do another video if people are interested.
In this video I show how I added simple LED panel lights to serve as brake indicators in the existing tail lights with no other modifications. It takes a 3D printer to make the parts, and I'm sure several people will be interested in how the parts are made as well.
