example 1

[0026] 1. Use Solidworks, Rhino and other three-dimensional modeling software to design the required porous structure, and calculate its porosity, adjust according to the mechanical simulation results of the finite element analysis software ABAQUS, and obtain the structural model with the best porosity.

[0027] 2. Configure the special slurry required for printing, use photosensitive resin as the solvent, add appropriate amount of ferric oxide powder, binder, photoinitiator, and photopolymerizer in sequence, mix thoroughly and then perform ball milling.

[0028] 3. Use the designed BESK printer to print. First, import the printed model data into the Q3DP software designed with the printer, adjust the parameters and slice the model, and then adjust the substrate to be parallel to the bottom resin tank and determine the best starting position , to ensure that the curing effect of the first layer is good, and start normal printing after confirming that the printing effect of the ...

Abstract

A method for preparing ferroferric oxide with a porous honeycomb structure based on light-curing 3D printing forming technology belongs to the fields of 3D printing technology, industrial metal, environmental treatment, and medical application. DLP (Digital Light Curing) 3D printing technology has the advantages of fast forming speed, high precision of printed models, and low cost. The present invention is realized by the following software and devices. Use Solidworks to design and optimize the 3D model, import the model into Q3DP software for slicing, prepare the slurry according to a specific ratio and perform ball milling, pour the slurry into the resin tank of the BESK printer to start printing, and put the green body after printing Debinding and sintering takes place in a medium furnace according to specific parameters. Finally, the Fe3O4 structure with excellent electromagnetic properties and a porous honeycomb structure is obtained. It has good adsorption capacity for heavy metal ions, and the removal rate is as high as 85%-90%. It can be used in environmental governance and medical fields.

Description

technical field [0001] The present invention relates to 3D printing technology and industrial metals, environmental management, and medical application fields, especially the use of DLP (digital light curing) 3D printing technology to prepare a ferric iron tetroxide honeycomb structure with good electromagnetic properties for adsorbing heavy metal ions . Background technique [0002] Magnets have good adsorption properties, especially for heavy metals such as cadmium, lead, copper, nickel, chromium, etc. Ferric oxide (Fe 3 o 4 ) is a typical magnet. The sewage produced by modern industry often contains a large amount of heavy metal ions. The current treatment methods include chemical precipitation, chemical reduction, solvent extraction and separation, and adsorption. The chemical precipitation method is difficult to remove; the chemical reduction method has high cost of chemicals and high processing costs; the loss of solvent in the extraction process and the large energ...
