Embodiment 1

[0043] In this embodiment, there are two storage syringes, namely ① and ②. Fill the molded silicone glue into the syringe ①, and fill the silicone curing agent into the syringe ②. The mass ratio of silica gel and curing agent is 100:2.5. On the 3D printing slicing software, set the wire diameters of ① and ② print heads to 1 and 40 respectively, and set the temperature of the hot bed to 50 degrees for offline printing.

Embodiment 2

[0045] In this embodiment, there are two storage syringes, namely ① and ②. Fill the syringe ① with glue A of epoxy resin AB glue, and the syringe ② with glue B of epoxy resin AB glue. The mass ratio of glue A and glue B is 1:1, and then on the 3D printing slicing software, set the wire diameters of the print heads of ① and ② to 1.75 and 1.75 respectively, and set the temperature of the hot bed to 60 degrees for offline printing .

Embodiment 3

[0047] In this embodiment, there are two storage syringes, namely ① and ②. Fill the syringe ① with 4.5 grams of corn starch, 22 grams of acrylic acid, 9 grams of acrylamide, 4.5 grams of calcium carbonate, 9.5 grams of sodium hydroxide, and 30.5 grams of water; 3.5 grams, 6.5 grams of N,N-methylenebisacrylamide, 10 grams of water. Then, on the 3D printing slicing software, set the wire diameters of ① and ② print heads to 1.75, and set the temperature of the hot bed to 70 degrees for offline printing.

Abstract

The invention provides a reaction type 3D printer which is characterized in that the reaction type 3D printer comprises a housing, and a discharge device, an air flow control system, a forming chamber, an exhaust system, a movement control system and an operation panel that are located in the housing; the discharge device comprises a mixer, and two or more storage needle cylinders; the air flow control system comprises an air delivery pipe and an electromagnetic valve or an electromagnetic valve or an electromagnetic switch for controlling on-off of high pressure air; the forming chamber is internally provided with a forming substrate; the exhaust system comprises a cooling device (like a cooling ventilating fan) and a tail gas exhaust device (like a ventilating fan) for exhausting reaction tail gas; and the movement control system is used for controlling movement of various components. Compared with the prior art, the reaction type 3D printer is wide in material application range, simple to operate, and easy to maintain and popularize, and can meet the printing requirements of 3D printing on multi-material printing.

Description

technical field [0001] The invention relates to the field of new equipment manufacturing, in particular, the invention provides a reactive 3D printer. Background technique [0002] Additive manufacturing technology (also known as "3D printing") is a method of directly manufacturing three-dimensional physical entities in a layer-by-layer manner based on a computer-based three-dimensional CAD model. Additive manufacturing technology can quickly and precisely manufacture parts of any complex shape and structure on one piece of equipment, thus realizing "free manufacturing". Compared with traditional processing technology, additive manufacturing can reduce processing costs by more than 20%-40%, and shorten product development cycle by about 80%. In the past 20 years, additive manufacturing technology has developed rapidly, and a variety of molding technologies and equipment have been formed. These technologies are aimed at high-end manufacturing fields such as aerospace, weapo...
