The UP! personal 3D printer from China, is designed and marketed to be an affordable and portable 3D printer for home use. It costs around $1500 for the fully assembled printer, with refill plastic costing around $50 per kg. It has a resolution of 0.3mm. The finished models show striations from successive layers of printing, but minimal sanding results in a smooth finish.
If an object is an irregular shape, featuring extrusions, or unable to stand without support, the printer software conducts a full analysis and adds support struts on the fly. These have to be removed with a hobby knife or scalpel after printing.
