Driving wheel 102 is rotated, so as to be moved to predeterminated position by room 7 is built.
In the present embodiment, setting for movable pulley 102 can reduce structure room 7 and ground while mobile structure room 7
Frictional force, so as to reduce the mobile power built needed for room 7, reduces energy resource consumption, saves resource.
Further, including lift in height mechanism 9, for rising or falling structure room 7.When needs are moved room 7 is built
To the lower section of main platform 5, risen using lift in height mechanism 9 by room 7 is built, consolidated structure room 7 with main platform 5 with facilitating
It is fixed.After molding component, room 7 will be built and pulled down from main platform 5, then dropped using lift in height mechanism 9 by room 7 is built
It is low, room 7 will be built from 5 times removals of main platform to facilitate.
Further, cylindrical 3D printing main body equipment also includes the 3D printer work for being arranged on the top of main platform 5
Industry room 6；On 3D printer work-room 6, positioned at the top of installing port, powder injection is provided with；It is provided with powder injection
Note powder switch for opening or closing note powder mouthful；Build the lower section that shaped device is arranged on main platform 5；Powder supplies system
System is arranged on main platform 5.
In the present embodiment, main platform 5 is fixed on the ground, powder supplies system be arranged on main platform 5 on, component into
Type device is arranged on the lower section of main platform 5, and 3D printer work-room 6 is arranged on the top of main platform 5.3D printer operation
Powder injection and note powder switch are set on the outer wall of room 6.User opens powder injection, Ran Houtong by noting powder switch
Cross powder injection and metal dust is injected into powder feeding cylinder 21, the metal dust in powder feeding cylinder 21 is laid on operation by powdering cylinder again
On platform 4.
Further, on 3D printer work-room 6, positioned at the top of installing port, be set to residual powder suction outlet and
Suction powder for opening or closing residual powder suction outlet is switched.
After molding component, user opens residual powder suction outlet by inhaling powder switch, passes through residual powder suction outlet
The residual powder that will be built in room 7 is suctioned out, and structure room 7 is then pulled down again, will build room 7 from the moved out from beneath of main platform 5, finally
Shaped component is taken out.
On the basis of above-described embodiment, further, operation post 4 is in annular including what is from top to bottom set gradually
Substrate 41 and build room piston plate 42；Build room piston plate 42 and be connected with building room piston 8；The width of substrate 41 is respectively less than structure
The width of room piston plate 42；The width for building room piston plate 42 is identical with the width of installing port.
In the present embodiment, the size of substrate 41, which is less than, builds piston plate, and the size for building piston plate is equal to the chi of installing port
It is very little, after the metal dust in powder feeding cylinder 21 is laid on substrate 41 by powder-laying roller, piston is built because the size of substrate 41 is less than
Plate, unnecessary metal dust, which can slide downwards, to be built on room piston plate 42, and the beneficial effect so designed is：In maximum operation
Face both formed between the area of substrate 41 and the installing port of main platform 5 together with safety work band, metal dust can be avoided selectively molten
With main platform 5 metallurgical connection occurs for the shaped component after change.
On the basis of above-described embodiment, further, the embodiment of the present invention also provides a kind of 3D printer, the 3D printing
Machine includes control system and the cylindrical 3D printing equipment such as the present invention；Powdering drive mechanism 12 is electrically connected with control system
Connect.The principle of cylindrical 3D printing equipment ibid, will not be repeated here.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
