Renault Trucks Shows us the Future of 3D Printed Engines

Renault Trucks shows how industrial 3d printing could drastically reduce weight and number of parts needed for a modern internal combustion engine. The weight is reduced by 120 kg and the number of parts is reduced by 200. This could lead to lower fuel consumption, cheaper engines and simpler replacement parts chain.

DIY Gauss Meter with 3D Printed Enclosure

Anthony aka. "Proto G" published this Instructable where he made a useful DIY Gauss meter which is controlled with Arduino Nano. 

Project description:
In this instructable, I will show you how to make a Gauss meter than can measure the strength of magnets so you can compare different magnets you have. It measures the magnets in units called Gauss and has a relatively linear range from 0-4000 Gauss. It will measure beyond that but the numbers beyond 4000 Gauss should only be used for comparison purposes. In addition to measuring the field strength, it also detects the polarity of the magnet and will show North or South, respectively. My favorite part about this design is the ON/OFF switch. It's hidden in the enclosure so the meter can only be turned on and off with a magnet. Since this unit is meant to measure magnets, you're sure to have one on hand. You can use the same latching magnetic switch I designed for many other things like a secret compartment lock. Here's a video showing the complete assembly:

RooBee One Open Source DLP SLA 3D Printer

Aldric Negrier developed this DLP projector based open sourced 3d printer. It looks easy to assemble and cheap to make. It all depends on how cheap can you find a suitable projector. 

Project description:
Roobee One is an SLA DLP 3D printer inspired on the Cristelia - SLA/LCD 3d printer and the Vulcanus MAX 3D printer.
It is built out of 20x20 mm aluminum profile chassis, It has an adustable print area of 80x60x200 mm up to 150x105x200mm build volume using a ACER DLP projector.
The open-source machine is called RooBee One because it is red color just like a Ruby gem.

Why Millebot?

Millebot is a large 3d printer that lives inside a shipping container. The idea behind it looks interesting...

... BUT

Why use this strange paste / foam for 3d print? and then mill it afterwards?

Building retainer walls for anything? Are you serious?

The operation will need a LOT of electrical power, material and overall complex logistic support.

Nice try, but I think it still needs a use case and overall technology improvements.

Low Cost DIY SLS 3D Printer by Vulcaman

Vulcaman, well known for his previous machines, has released his latest sintering 3d printer you can make for some 500 Euro: the JRLS 1000.
It is still far from commercial machines, but this field is progressing forward and that is the most important thing. Vulcaman is only 18 years old, so we can hope much more from him in the future.
Key features:
  • 5x5x5cm build volume
  • 1.8w 445nm laser
  • 80w 12V heated-bed
  • 150w 230V powder heater with IR-Sensor
  • coater which compresses the powder
  • adjustable Feed control
  • overflow container
  • closed build chamber
  • low cost
Most prints are currently done in instant tea powder which is 95% sugar, but the powder is used because of its red color which will absorb the 450nm laser well. White sugar will not work, because it will just reflect the laser. The laser is focused to 0.2mm. The power of the laser is set to 1W.

Here is the machine printing:

How crazy are the Finns?

Well ... besides crushing various thing in a hydraulic press they also use LARGE 3d printers at Prenta to make molds for pykrete stuff. Pykrete ammunition to be more specific.

And then they use that ammo in a BIG air cannon:

I like Finland!

Dtto 3D Printable Modular Open Sourced Transformer Robot

Dtto robot is just cool! See it here in the video presentation:

Project description:
The Dtto v1.0 Robot is a modular transformable robot designed to be versatile, flexible and self-reconfigurable. The idea of modular robots is that they can adopt any shape they want, by changing the position and the connection of their modules.

This robot is aimed for research on modular self-reconfigurable robots and educational purposes. It is designed to allow multiple modules to communicate, mechanically connect and disconnect and to work collaboratively in the locomotion, self-reconfigurability and efficient movement.

The versatility of the robot will allow it, in the future, to be able to perform rescue operations, exploration of unknown environments and space exploration.

In future works, the modules will have built in camera, ultra-sound sensor, gyroscope, accelerometer, magnetometer… The possibilities are endless.

Dtto key features:
  • Small and self-contained robot
  • Fully 3D printable
  • Self-reconfiguration capabilities
  • Bluetooth + Radio communication
  • Multiple locomotion modes (snake, wheel, walker...)
  • Rechargable batteries
  • Simulation model validated
  • Cheap modules (<55 USD)
  • Open Source Hardware and Software

Dtto is made from modules:
