3D printed parts in the CARESTO ARKHAM CAR . 2016 . Gumball 3000
Palmiga Innovation – Rubber3Dprinting.com had the absolute privilege to contribute with 3 pieces of rubberlike PI-ETPU 95-250 Carbon Black 3D prints to this amazing build by Caresto AB.
This one of a kind car is built by Caresto to be part of Gumball 3000, 2016. The design is based on the car from the Arkham knight game but has been redesigned and manufactured with drivability and full functionality in mind. The car is BIG. The wheel base is 3.40 meters and the width of this special car is 2,5 meters. The special high rigid tubular frame is manufactured to provide good handling and give a solid feeling.
Front and rear suspensions are fully independent and made with double wishbones connected to the coil over shock absorbers, up front through a special designed aluminum push rod. To power the car, we have used a 560hp V 10 engine connected to a paddle shift gear box affecting the 26″ wheels. To stop the car we have used ABS supported 8-pot Brembo calipers in front and 6-pot in rear all connected to big brake discs.
The complicated all carbon fiber body has been made from full scale moulds which are milled out from the CAD drawings. A lot of effort has been made to the design of the drawings and moulds. This to get the correct stance with full working systems and parts that will work together. Inside the car the driver and the passenger can enjoy the interior in a combination of black soft leather and “see trough” fabric, all kept together by golden stitches. The interior lights up in seats, floor and pedals when the cockpit opens up fully electrical operated. All comfort functions such as climate system, power steering, fantastic sound system, etc helps to make this car a comfortable driver, even that the look is hard as steel.

The headrest logos, as well as the center cap for the steering wheel, where 3D printed on a normal consumer 3D-printer using the flexible rubberlike PI-ETPU 95-250 Carbon Black (Rubber3Dprinting.com).
The center cap was the most challenging part to 3D print, the big radius convex surface would not look nice using a 0.4mm nozzle… Instead a 0.7mm nozzle was used but the extrusion width was set to 0.9mm to get the layers to look nice with circular rings covering the complete surface. Also the thickness of only 1,5mm and the need for support material made this a tricky job. To show how nice the PI-ETPU 95-250 Carbon Black filament is to use, the same filament was used as support material, using a single extruder 3D printer.
The surface of the bat symbol was manually melted with a solder iron and smoothed out using sandpaper, that process was a bit delicate but resulted in the nice structure and contrast needed.
To 3D print the headrest parts was rather straight forward when using a 0.7mm nozzle and also a small positive extrusion multiplier to adjust the feel and look, they were printed flat with holes etc ready for the sewing.
Even if my part has been very small in this car project it has been extremely fun and I feel truly privileged, I can only wish for more…
