Cube one of the most prominently featured end designer focused machines on the market. The incorporation of reusable material cartridges is exciting as it removes a lot of the technical aspects of printing. Although the media would have us believe that additive manufacturing is as easy as hitting print that is not the case. Melting a material and depositing it in a specific location is a difficult process that requires the attention and engineering skills of trained materials science experts. Every change to a material can affect its performance, the addition of color, a compound change, dust or other debris.
From the industry side replaceable cartridges also provide a slightly varied business model. If 3D systems succeeds in selling millions of cubes they will have in place an installed user base that is dependent upon their cartridges (currently each one is $49 dollars) that can fund growth and hopefully further development into new materials, new printers, and new technology altogether.
The look and style of the Cube is also notable. Still in their infancy, many current printers are essentially one step above a garage prototype. The backing of a large organization and dedicated software teams means the cube is aesthetically pleasing and hopefully the user experience only continues to get better.
