A concrete scheme is, wherein runing rest is collar plate shape, along this runing rest be radially provided with chute, one end of printing head support part is provided with the slide block matching with this chute.
From above scheme, realize printhead in the motion upwards of runing rest footpath by the slide block on one end of printing head support part with being located at mating of runing rest footpath chute upwards, simple in structure, cost is low.
Another concrete scheme is, on the central shaft that is centered close to runing rest of work support to be printed.
From above scheme, can easily the central shaft of workpiece to be printed be adjusted into the central shaft of runing rest and be overlapped, in runing rest rotary movement, can reduce printhead amount of exercise radially.
Another concrete scheme is that printhead is ink jet-print head.
From above scheme, can realize and treat the surperficial inkjet color printing of printing workpiece.
Another concrete scheme is that printhead is that laser sprays carbon dust printhead.
From above scheme, can realize and treat the surperficial carbon dust colour print of printing workpiece.
Concrete scheme is that this three-dimensional printer also comprises the printhead that can spray light-cured resin.
From above scheme, can be after carbon dust be sprayed on the surface of workpiece to be printed, and spray one deck light-cured resin, then carry out photocuring, make the multicolour pattern after printing more firm.
One more specifically scheme be that the quantity of printhead is at least 2.
From above scheme, owing to thering are multiple printheads, can adjust the locus of multiple printheads simultaneously, realize many places and print simultaneously, improve printing effect.
Another more specifically scheme be that printhead is arranged on printing head support part in the adjustable mode of axial angle of the relative printing head support part of its injection direction.
From above scheme, because the angle between the injection direction of printhead and the axial direction of printing head support part is adjustable, when the normal direction of printing surface printing head support part axially with the plane of injection direction formation on projection and injection direction when inconsistent, the injection direction of printhead can be adjusted into identically with the direction of projection, be particularly suitable for bus for the surface of the revolving body of straight line prints.
Another more specifically scheme be that printhead is arranged on printing head support part in the axial adjustable mode of circumferential corner around printing head support part.
From above scheme, because printhead is adjustable around the axial circumferential corner of printing head support part, when the projection on the normal direction of printing surface and axial perpendicular cross section at printing head support part and injection direction are when inconsistent, the injection direction of printhead can be adjusted into identically with the direction of projection, being particularly suitable for bus is the surperficial printing of the non-revolved body of straight line.
