Abstract

The invention discloses a piston and pneumatic type 3D printing biological material extrusion test device. The piston and pneumatic type 3D printing biological material extrusion test device comprisesa box, a piston component, a mixing component, a pushing component and an air pressure component and is characterized in that a temperature-adjustable extrusion test environment is formed in the box;the piston component comprises a cylinder, a piston and a piston rod, one end of the cylinder is provided with a needle, guide channels communicated with the cylinder are arranged in the piston rod and the piston, materials mixed by the mixing component flow into the cylinder, materials in the cylinder are extruded by the piston rod pushed by the pushing component, and the materials in the cylinder can also be extruded by feeding air flow into the guide channels; various data is collected through a displacement sensor and a pressure sensor during the material extrusion, and the materials arereceived by a receiving plate and weighed by an electronic scale. By the structure, the test device has the advantages that high precision is achieved, test efficiency is increased, the labor intensity of test staff is lowered, the extrusion curve of the test materials can be measured in real time, and data and guidance can be provided for actual production and design.

Description

technical field [0001] The invention relates to the field of 3D printing biological material extrusion test equipment, in particular to a piston and pneumatic dual-purpose 3D printing biological material extrusion test device. Background technique [0002] In the biological 3D printing system, it is particularly important to accurately extrude the printing material. However, in the actual application process, due to the wide variety of biological materials, and most of them are non-Newtonian fluids, it is difficult to calculate their extrusion parameters theoretically. Therefore, empirical methods and trial and error methods are basically used to solve the precise extrusion of specific materials. Something went wrong. Such methods are not only time-consuming and labor-intensive, but also waste valuable biological material. [0003] Therefore, it is necessary to develop a set of special test equipment in order to solve the above problems efficiently and at low cost through ...
