Abstract

The invention belongs to the technical field of 3D printing. The invention discloses a rockery bonsai 3D printing material, which is prepared from the following raw materials: 35-70 parts by weight of base materials, 20-55 parts by weight of light materials, and 5-10 parts by weight of water-soluble polymers; the rockery of the invention Bonsai 3D printing materials use a large amount of harmless industrial and construction waste and agricultural waste, which can realize the recycling and reuse of waste resources, make full use of resources, and reduce the pressure on the environment; it has the characteristics of good fluidity and strong plasticity , can be applied to 3D printing technology, during the 3D printing process, there will be no problems such as clogging the catheter cavity; after 3D printing, the strength can be quickly obtained, ensuring that the formed green body will not collapse and other problems; the prepared The rockery bonsai has a rich honeycomb cavity structure, which has the advantages of light weight and good water absorption.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing material for rockery and bonsai. Background technique [0002] With the progress of society, people's living standards are gradually improving, and they pay more and more attention to interior decoration; rockery bonsai has become a popular interior decoration. But in the prior art, rockery bonsai is made by natural rock, or is made by moldings such as resin; Wherein the rockery bonsai that natural rock makes is limited by the shortcoming of natural rock and has shortcomings such as single shape, heavy weight, etc., is often suitable for It is not very suitable for interior decoration to be placed in a wide place such as a courtyard; and the rockery bonsai made of resin modeling is not realistic enough, the weight is too light, and there are resin additives that release residues such as benzene and olefins, etc. Hazards from Hazardous Substances.
