Abstract
The present invention is the moulding process of the dedicated modified powder of 3D printing, is comprised the step of: A: selection modifying agent: one or more of in stearic acid, lauryl sodium sulfate, 5040B and the solidifying modifying agent of rush；B: ingredient proportion is selected: modifying agent: calcium sulphate dihydrate 0.8:1-10；C: selection decentralized medium: one or more of dehydrated alcohol, acetone, ethyl acetate, butyl acetate；D: reaction step: weighing modifying agent and calcium sulphate dihydrate by ingredient proportion, is added in 50-200g decentralized medium, and heating stirring, setting bath temperature is 50-89 DEG C, speed of agitator 200-480r/min, and mixing time is 0.5-3 hours.The present invention has reached the quick-hardening demand in 3D printing technique forming process, has improved the printing precision of mold by the modification to calcium sulphate powders, greatly shortening calcium sulphate powders firm time.
Description
Technical field
The present invention relates to 3D printing field more particularly to the moulding process of the dedicated modified powder of 3D printing.
Background technique
3D printing (Three Dimension Printing) technique is using 3 D stereo forming technique, using ceramic powder
The dusty materials such as end, metal powder, gypsum powder and some hot melts or light-cured resin etc., by spray head binder by zero
The section of part is printed upon above material powder, or moulding resin is sprayed in layer, solidifies molding bonded respectively, molding
Process is that each two-dimensional section overlapping bonding is become a 3D solid.It is fast with speed, it is suitble to the zero of manufacture complicated shape
Part can be used for manufacturing the part of composite material or heterogeneous material, can manufacture parts in small batch, can also manufacture complicated shape zero
Part, it is pollution-free.3DP is one of the hot spot of current rapid prototyping technology research, and application prospect is very good.
Powder for molding part is made of filler, binder, additive etc..For opposite other conditions, the partial size of powder is non-
It is often important.The small particle of diameter can provide mutual stronger Robert Van de Walle hereby power, but rollability is poor, and in print procedure easily
Fugitive dust causes print head to block；Big particle rollability is preferable, but will affect the printing precision of mold；Secondly, needing to select
Quartz sand, ceramic powders, gypsum powder, polymer powder may be selected (as gathered in energy rapid shaping and the preferable material of processability
Methyl methacrylate, polyformaldehyde, polystyrene, polyethylene, paraffin etc.), metal oxide powder (such as aluminium oxide) and shallow lake
The filler body as material such as powder, selects matched binder i.e. and can reach the purpose of rapid shaping.
For this purpose, the moulding process of the design dedicated modified powder of 3D printing, solves problem above.
Summary of the invention
The present invention is to overcome the above deficiency, provides the moulding process of the dedicated modified powder of 3D printing, comprises the step of:
A: selection modifying agent: one or more of in stearic acid, lauryl sodium sulfate, 5040B and the solidifying modifying agent of rush；
B: ingredient proportion is selected: modifying agent: calcium sulphate dihydrate 0.8:1-10；
C: selection decentralized medium: one or more of dehydrated alcohol, acetone, ethyl acetate, butyl acetate；
D: reaction step: weighing modifying agent and calcium sulphate dihydrate by ingredient proportion, is added in 50-200g decentralized medium,
Heating stirring, setting bath temperature are 50-89 DEG C, speed of agitator 200-480r/min, and mixing time is 0.5-3 hours, institute
Powder is obtained by filtering, and 0.5-2.5 hours dry in 120-220 DEG C of baking oven.
Further, it is coagulant 200, coagulant 600, coagulant 2000 and coagulant 6000 that the rush, which coagulates modifying agent,
One or more of.
Preferably, the moulding process of the dedicated modified powder of the 3D printing further includes the sieving of step E product, the step
Rapid E product sieving passes through 200 meshes for the product after filtering drying.
The beneficial effects of the present invention are:
The moulding process of the dedicated modified powder of 3D printing of the present invention, by the modification to calcium sulphate powders, greatly
Shorten calcium sulphate powders firm time, reaches the quick-hardening demand in 3D printing technique forming process；Dispersed by addition
Agent keeps relatively independent between powder, to there is preferable rollability, solves Yi Yangchen in print procedure, leads to print head
The problem of blocking, improves the printing precision of mold.
Specific embodiment
It is described in detail below with reference to the embodiment of the present invention.

C: selection decentralized medium: one or more of dehydrated alcohol, acetone, ethyl acetate, butyl acetate；
D: reaction step: weighing modifying agent and calcium sulphate dihydrate by ingredient proportion, is added in 50-200g decentralized medium,
Heating stirring, setting bath temperature are 50-89 DEG C, speed of agitator 200-480r/min, and mixing time is 0.5-3 hours, institute
Powder is obtained by filtering, and 0.5-2.5 hours dry in 120-220 DEG C of baking oven.
Further, it is coagulant 200, coagulant 600, coagulant 2000 and coagulant 6000 that the rush, which coagulates modifying agent,
One or more of.
Preferably, the moulding process of the dedicated modified powder of the 3D printing further includes the sieving of step E product, the step
Rapid E product sieving passes through 200 meshes for the product after filtering drying.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
