There is a new RepRap in town!

Feb.20, 2013

There is a new RepRap in town! Kiel-based Kühling&Kühling from Germany published first details on their new RepRap design after a full year of development.Founded by mechatronics engineering students Jonas Kühling and Simon Kühling in 2012, Kühling&Kühling has a goal: to build high productivity open-source 3D printer that requires minimal maintenance.

Named "Kühling&Kühling RepRap Industrial", the 3D printer has a fully enclosed frame with powerful recirculating chamber heaters that raise the ambient air temperature up to 70°C. It features two extruders that allows 3D printer to print with different nozzle diameters. One is for printing the visible outer shell of an object in fine details and another, for saving production time, can be used for printing infill structure by using a bigger extrusion nozzle. You can also just use it for two-color printing.


* Filament diameter: 3mm Build volume: 200mm x 200mm x 200mm
* Number of extruders: 2
* Overall dimensions: 800mm x 600mm x 600mm


* Printing ABS with zero warping
* Rigid frame made of 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
* Activated-carbon air filter to remove unpleasant smell of molten plastic
* 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
* 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
* Custom designed, precision extruder drive gears to provide enough grip on the filament in a heated enviroment
* Integrated LED lighting

  2. Hi there,

    I am very much charmed to see and read this great contentg. Really very good post.I think it is very informative and will be helpful for people.Thanks for sharing this nice post.Lighting technology saw a huge change with the emergence of LED's, which slowly replaced the age-old incandescent lamps and bulbs that were being used previously.Taka a look at at: led accessories
