Happy birthday Morgan!

First prints of RepRap Morgan, the SCARA arm 3d printer designed and built by Quentin Harley.

3d printed WiFi antenna signal amplifier

Great idea from iphands: he designed and printed parabolic WiFi antenna signal amplification dish. Foil was glued on.
He notes that the signal was amplified from 1200-1500KBps (~12mbps) to 2000-2500KBps (~20mbps) on an old WRT54G.

DAS RepRap - Kühling&Kühling RepRap Industrial

Here is DAS RepRap or üBER RepRap: Kühling&Kühling RepRap Industrial. It's the Mercedes Benz of RepRaps.

Demo of tool-free belt tensioning system:

Features

Specifically aimed at printing ABS with zero warping, low maintenance effort through highly accessible sub assemblies
Rigid frame made of 20x20mm t-slot aluminium extrusion
Fully enclosed by acrylic and wood, doors on the front
A heated chamber capable of 65-70°C recirculating air temperature
Heated PCB print bed
Water cooled hot-ends and extruder steppers to ensure reliable extrusion in high ambient air temperature
Fully parametric design in OpenSCAD
Dual extruders, primarily for use with different nozzle diameters for perimeters/infill to save printing time on big objects (we are testing with 0.35mm for perimeters and 0.75mm for infill at the moment)
3mm filament diameter
Compact, rigid parts with integrated mounting points for endstops and such
Activated-carbon air filter to remove unpleasant smell of molten plastic
Cable management
Semi-automatic print bed levelling makes calibrating the machine a matter of seconds
Z-leadscrew bearing supported on both ends, sugru spider coupling for absolutely wobble-free operation
12mm precision ground shafts with LM12UU linear ball bearings on all axes (will be replaced by Igus RJMP, see below)
Tool-free belt tensioning with built-in thumbwheels
Direct-drive extruders with high torque geared stepper motors
Permanent printbed material (FR4) – no Kapton or PET tape needed
Adjustable nozzle height to align both extruders on the same level
200x200x200mm build volume
Custom designed, precision extruder drive gears to provide enough grip on the filament in a heated enviroment
Integrated LED lighting
Hotends from reprap-fab.org with 40W each for short heat up time

Electronics

RAMPS 1.4 controller board – we will give the R.U.M.B.A. a try as soon as it is delivered.
Modular additional MOSFET driver boards for lights and fans
Brand new high power 15A MOSFET driver boards (still in development bycarbonfrog) for chamber heaters, total power >550W
ATX power supply 1000W
Water cooling based on a EHEIM/Innovatec PCPS1104 water pump

Upcoming development

Raspberry Pi with a 10″ capacitive touch interface for ethernet enabled standalone operation
Touch optimized user interface for the raspberry pi is in development
The frame will be revised for 30x30mm extrusions, so we can use T-slot nuts that can be swivelled in, providing much easier assembly. These nuts are poorly available for 20x20mm extrusions
All LM12UU linear ball bearings will be replaced by low maintenance Igus RJMP slide bearings that are rated for continuous use in 90°C ambient temperature
Magnetic door locks

Price: unknown, it's still under development

DIY RepRap with triple extruder setup for mixing and blending multicolored filament

RichRap2011 shows off his 3 extruder setup with a single hot-end combining nozzle, to 'mix' and blend colored filament plastic or different materials on a RepRap 3D printer. It was some time before new RepRapPro Mendel Tricolour which does not mix colors.

SCARA 3d printers

The SCARA acronym stands for Selective Compliant Assembly Robot Arm or Selective Compliant Articulated Robot Arm. By virtue of the SCARA's parallel-axis joint layout, the arm is slightly compliant in the X-Y direction but rigid in the ‘Z’ direction, hence the term: Selective Compliant.
The second attribute of the SCARA is the jointed two-link arm layout similar to our human arms, hence the often-used term, Articulated. We will see how this concept develops. Nice new innovation after Delta approach.

Here is the first video of SCARA used for 3d printer by ttsalo (http://github.com/ttsalo/Armstrong-SCARA)

Here is RepRAP Morgan, a more sophisticated SCARA FDM 3D printer developed by Quentin Harley

Optomec Aerosol Jet 3d printed electronics

In video bellow Stratasys 3D Printer is used to created the wing structure for an Unmanned Air Vehcile (UAV). Then an Optomec Aerosol Jet System is used to print electronics onto the wing structure including an RF antennae, sensor, and circuitry to power a propeller and LED. All electronic are functional. The RF antennae broadcasts live video from a camera to remote display screen.

Here is the same technology in action at Sirris:

RepRap Tricolour Mendel is out!

RepRapPro has their Tricolour Mendel out. It is designed to work with three colours or three different plastics at the same time. They also plan future usage of electrically-conducting plastics, magnetic plastics and soluble support materials. Great to see that the technology is advancing. Hopefully first reviews of the working machine in real world applications will be out soon. It is priced around 1000 USD.

Specs:

Build volume: 210x190x140mm
Overall size: 500x460x410mm
Printing materials: ABS, PLA, 1.75mm diameter thermoplastic.
Build surface: PCB-heated bed to reduce complexity of assembly and to ensure parts do not warp. Computer interface: USB
X-carriage: Three Z-adjustable deposition heads.
Accuracy: 0.1mm
Resolution: 0.0125mm
Building speed: 1,800 mm/min
Moving speed: 12,000 mm/min
Deposition rate: 33 cm3 / hr
Motion: Linear ball bearings on X and Y axes, Igus low friction bushings on Z axis.
Pre-soldered electronics with built-in microSD card slot for standalone printing.
enhanced widely-used Marlin firmware allowes the addition of a slave controller board to drive the extra extruders.
Arduino-compatible Melzi electronics for both the master and slave controllers.

JP Aerospace 3d printed PongSats

I'v blogged about 3d printed satellites HERE before, but PongSats are new project I found. Basically they are launching ping-pong ball sized nano satellites to the edge of space with helium balloons.

Video of the full flight:

Flomio embeds NFC into your 3d models

New service from Flomio that enables you to make your 3d printed models interact via embedded NFC tags. Effective for anti-counterfeiting, AR gaming solutions, marketing etc...

http://flomio.com/shop/nfc-tags/nfc-custom-3d-printables/

From their site:

Have a 3D solid modeled object that you want to print out with an NFC Tag embedded inside? We can help you with that.
We charge $0.50 per cm3 as well as a $4 handling fee per item. Additional is your NFC tag of your choice and shipping. Object build size must be larger than the NFC tag. We can print embedded NFC 3D objects as large as 15cm cubed.
Here’s out it works:
Send us your 3D solid model file (.stl format only).
Choose your build size, NFC Tag, and color plastic (white, green, or blue)
We price it out and if you’re happy, we 3D print it.
We test it.
We mail it to you.
