Embodiment 1

[0036] A 3D printing method 100 of polyether ether ketone, such as figure 1 shown, including:

[0037] Step 110, setting the 3D printing parameters used to form the polyetheretherketone sample with preset shape memory properties, the 3D printing parameters include: filling density, printing speed, nozzle temperature, hot bed temperature, nozzle diameter, extrusion Magnification, layer thickness, and printing angle;

[0038] Step 120, using polyetheretherketone wire to print the base through fused deposition;

[0039] Step 130 , according to the above printing parameters, print the polyetheretherketone sample with preset shape memory performance on the base.

[0040] The verification method that the polyetheretherketone sample obtained by the 3D printing method of polyetheretherketone has preset shape memory performance can be:

[0041] The polyetheretherketone sample is naturally cooled, and the shape of the sample is the original shape at this time; the sample is heated to...

example 1

[0059] (1) Carry out thermal pretreatment to the polyether ether ketone wire rod with controllable shape memory performance, by putting the polyetheretherketone wire rod into a vacuum oven, the temperature is 160 ℃ under vacuum condition and heating for 2 hours to remove the inside of the wire rod Moisture; set the filling density of 3D printing parameters to 100%, printing speed to 30mm / s, nozzle temperature to 410°C, hot bed temperature to 110°C, nozzle diameter to 0.4mm, extrusion ratio to 1, print layer thickness to 0.1mm, and print angle to 45° °; Then perform zeroing operation and pre-heating treatment on the nozzle and heat bed before printing.

[0060] (2) Printing: When the temperature of the nozzle of the printer and the hot bed reaches the preset temperature, the slicing of the 3D modeling sample requires pre-printing a layer of large base, and then printing according to the 3D printing parameters.

[0061] After printing the polyetheretherketone sample with control...

Abstract

The invention discloses a 3D printing method of polyether ether ketone and its printed sample. The method includes: setting 3D printing parameters for forming a polyether ether ketone sample with preset shape memory performance, including: filling density, Printing speed, nozzle temperature, hot bed temperature, nozzle diameter, extrusion ratio, layer thickness, and printing angle; use polyether ether ketone filament, through fused deposition, print the base; according to the above printing parameters, printing on the base has a preset Polyether ether ketone samples with shape memory properties. The present invention performs 3D printing with controllable shape memory performance on polyetheretherketone, according to the actual required shape, especially the filling density, printing speed, nozzle temperature, hot bed temperature, nozzle diameter, extrusion ratio, layer Thickness and printing angle are set, combined with fused deposition printing method for 3D printing, the PEEK sample with high controllable shape memory performance can be obtained, and the application range of PEEK is improved at the same time, and the practicability is strong .

Description

technical field [0001] The invention belongs to the field of 3D printing, and more specifically relates to a 3D printing method of polyether ether ketone and a printing sample thereof. Background technique [0002] 3D printing technology (also known as additive manufacturing or incremental manufacturing technology), which is based on a computer three-dimensional design model, creates a solid manufacturing method by layer-by-layer accumulation, bonding, and superimposition. Its main feature is that it is driven by computer three-dimensional design data, does not require the production preparations such as machine tools and mold manufacturing necessary for traditional manufacturing processes, and directly produces products of any shape through digital design without assembly, which greatly shortens the product development cycle. The process is simple, time-saving and labor-saving. [0003] Polyetheretherketone is a special engineering plastic with high temperature resistance ...
