Description
Technical Field
The invention relates to the technical field of 3D printing, in particular to a secondary processing and shaping method for a 3D printed PEEK repairing material.
Background
The PEEK fused deposition 3D printing is a technology for manufacturing PEEK solid parts by feeding PEEK filamentous materials into a spray head through a wire feeding mechanism through a CAD design data and control system, heating and melting the PEEK filamentous materials in the spray head, moving the spray head along the section outline and a filling track of the parts, simultaneously extruding the melted PEEK materials, rapidly solidifying the PEEK materials after extruding the PEEK materials under the control of a computer by utilizing the hot melting and the caking property of the PEEK materials, and bonding the PEEK materials with the surrounding PEEK materials to form the PEEK solid parts in a layer-by-layer stacking mode. The prepared PEEK part has excellent mechanical property, heat resistance, friction resistance, chemical resistance, hydrolytic resistance, heat aging resistance, fatigue resistance, creep resistance, irradiation resistance, weather resistance and the like, has been used as a light high-performance material with huge potential to replace a metal material to be applied to various fields, particularly has excellent biocompatibility and wear-resisting property, and becomes one of ideal materials of the current bioprosthesis implants. Therefore, the PEEK repairing material can be manufactured by 3D printing, so that the effective repair of the bone defect part of the human body can be carried out.
However, unlike the conventional 3D printed materials such as ABS and PLA materials, the PEEK material is a semi-crystalline thermoplastic material, the PEEK repair material printed by 3D printing generally has low crystallinity, and the part with low crystallinity has high flexibility and shape, can be bent and stretched under external load, and then cut according to the requirement, and can be hardened and shaped by increasing the crystallinity through high temperature tempering. However, the prior art has not achieved such a process.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to provide a method for secondarily processing and shaping a 3D printed PEEK repair material, which can perform secondary cutting, bending and processing on a pre-manufactured PEEK repair material, and then improve the crystallinity of the material through post-treatment, so as to increase the rigidity and strength of the material, shape the material and finally use the material on a patient.
In order to achieve the purpose, the invention adopts the following technical scheme:
a secondary processing and shaping method for 3D printing of a PEEK repairing material comprises the following steps:
1) according to the specific requirements of the biomedical treatment, three-dimensional models of the repair materials with different specifications, sizes and styles are designed;
2) manufacturing a low-crystallinity PEEK repairing raw material with high toughness and good plasticity by adopting a PEEK controlled 3D printing method, and storing and transporting the raw material in a sterile bag after cleaning, sterilizing and disinfecting;
3) then according to the actual demand condition, the PEEK repairing raw material can be subjected to secondary cutting, bending and processing, and finally the needed real repairing material is formed;
4) then the crystallinity of the material is greatly improved through a tempering heat treatment process, so that the rigidity and the strength of the material are increased and the material is shaped;
5) after mechanical inspection, sterilization, cleaning and disinfection, the product is finally used on patients.
The invention has the beneficial effects that: the invention provides a secondary processing and shaping method of a repairing material aiming at scenes in which rapid repairing operations are urgently needed, such as war, first aid and the like, thereby greatly shortening the application time.
