With reference to embodiment and compare accompanying drawing the present invention is described in further detail.It is emphasized that
What the description below was merely exemplary, the scope being not intended to be limiting of the invention and its application.
With reference to figure 1 below -2, non-limiting and nonexcludability embodiment, wherein identical reference table will be described
Show identical part, unless stated otherwise.
Embodiment one：
The FDM 3D printers of the present embodiment, as shown in figure 1, including fuselage and printhead 9, in addition to coordinate the printing
First 9 support meanss, the support meanss include：Workbench 5 and its working cylinder 2 and elevating mechanism 8 (can be motor or cylinder etc.
Actuating unit forms), granular propping materials 4 and its feed mechanism 1, inductor 3 and control device (not shown).It is described
Workbench 5 and its working cylinder 2 can carry out lifting action in the presence of the elevating mechanism, and the granular propping materials 4 can
It is delivered to by the feed mechanism 1 in the working cylinder 2.The elevating mechanism 8, feed mechanism 1 and inductor 3 respectively with it is described
Control device connects, and performs lifting and feeding operation according to the instruction of the control device, and the inductor is used to detect institute
The top side location of granular propping materials is stated, and produces induced signal and is sent to the control device, is sent out by the control device
Go out control instruction, to stop the feed mechanism and start printer (printing head 9 is only schematically illustrated in figure) and its institute
Elevating mechanism 8 is stated, continues to print the model 10.In figure, position indicated by P1 is the position of the model 10 printed, P2
Indicated position is the position of the also unprinted model 10.Indicated by A is that the top surfaces of the granular propping materials arrives
The position (need the position/height supported, or meet the position/height of default offset) reached, A faces are supporting surface,
For providing the support of printer model hanging part.
The preferred graininess of granular propping materials, it can be the solid particles such as sand, glass bead, metal powder, also may be used
Using liquid substances such as mercurys.The particle diameter of the granular particles shape backing material can be according to institute's printer model size, shape
Deng the appropriate selection of carry out.
The present embodiment further preferably includes being used for the percussion mechanism 6 and cylinder body fixed seat 7 for making the working cylinder produce vibrations, institute
