3D Printing a Fibreglass Camera Cable Harness with Markforged

One of the best things about 3D printing is it gives people the opportunity to solve everyday problems by making the solution to them. Here’s a case in point – Rent the Sky Films, a mixed media, motion control and animation studio, used their Markforged 3D printer to 3D print a fibreglass camera cable harness for their handheld camera.

The harness is a custom job designed in-house by the team. It consolidates cabling to a single interface point. It keeps the cables neat, tidy and ordered, so that the camera is easier to operate. It allows the team to carry a series of cabling while reducing weight. They now use a handheld 3D camera on jobs rather than a 100lb rig thanks to the extra functionality the cabling offers – in simple terms, it makes life on the job much easier.

RtS 3D printed the camera cable harness using Onyx, a chopped carbon fibre and nylon hybrid material (proprietary to Markforged), and reinforced it with continuous strands of Fibreglass. The result is an exceptionally strong harness that, pound-for-pound, is stronger than 6061 aluminium and less than half the weight.

In addition, fabrication time and costs have been slashed. The team can design and fabricate a new camera harness in around 9-hours with 3D printing, versus 1-week with CNC machining. The cost-per-part has been significantly reduced from an eye-watering $320 per harness to $19.71 per harness. To give you some more figures, it means the team now makes camera harnesses and other holders and casings 15x faster and 16x cheaper – and it’s all thanks to 3D printing.
