Description
Technical Field
The present invention relates to additive manufacturing devices, and more particularly to devices and methods for applying bondable materials to a movable carrier.
Background
Material jet 3D printing is a common 3D printing technique, also known as inkjet 3D printing or multi-material 3D printing. It is sprayed to a specific location through a spray head using a liquid or semi-solid material, stacked layer by layer to create a three-dimensional object. The spray head for material jet 3D printing is typically composed of the following parts: nozzle, heater, temperature sensor, pressure controller, valve. The arrangement of nozzles in the spray head varies with different 3D printing techniques and spray head designs.
In the existing rotary platform type 3D printing technology, rotary 3D printing is generally performed mainly based on polar coordinates, and the structure of the rotary platform type polar coordinate printer is as follows: the printing platform is positioned at the center of the printer and can perform rotary motion on a plane. The printing head is fixed at a fixed position, and continuous printing is realized by controlling the rotation angle of the printing platform. The print platform typically supports 360 degrees of rotation and can control the accuracy and stepping of the angle.
However, in the rotational 3D printing process, the following difficulties often exist:
1) The precision requirement of equipment design and manufacture is very high: polar printers require precise mechanical design and manufacture, and ensure smooth movement and high precision of the printer by high precision and stability of the manufacture and assembly of the components.
2) The control precision requirement is high, and the coordination requirement of each motion integrated control is high: polar printers have complex motion control systems. These control systems require high precision control of rotation and linear motion to ensure accurate positioning and movement of the print platform and print head; meanwhile, since the printing process involves coordination control of multiple movement modes, the control system is highly integrated, and coordination work of all parts needs to be ensured to realize efficient printing operation.
3) The printing strategy has poor universality and high control algorithm requirement: polar coordinate printers with different structures have different motion laws and printing paths, and different printers need to develop a special printing path planning algorithm so as to reduce the motion distance to the greatest extent and unnecessary movement, and improve the printing efficiency and quality; the motion of the polar printer is very complex, and advanced control algorithms need to be developed to achieve synchronization and calibration of the motion to ensure accurate alignment of the print platform and the print head.
4) The stability requirement of the printing platform is high: the polar printer needs to maintain the stability and balance of the printing platform to prevent shaking or shifting during printing, which would affect the printing effect once it is shaking or shifting. Thus, it is often complicated to consider the material selection, structural design, balance adjustment, and the like of the platform.
In 3D printing technology, besides the control of a rotating platform, the design and control of a spray head are mainly characterized in that the existing spray head is mainly divided into two types according to the arrangement mode of nozzles: a single nozzle arrangement and a multi-nozzle parallel arrangement.
1. Single nozzle arrangement: the spray head only comprises one nozzle, the material is sprayed through the single nozzle, the single nozzle can only spray in turn, after each layer of printing is finished, the nozzle needs to be moved to the next position to continue spraying the material, and the single nozzle is simple in arrangement structure and simple and convenient to debug and control.
However, the single nozzle arrangement has the following problems:
1) The arrangement mode of the nozzles is obvious, the printing speed is low, the product forming efficiency is low, various materials cannot be sprayed at the same time, a complex structure is difficult to realize, and the nozzle is generally applicable to some simple 3D printing applications and is used for creating a relatively simple structure.
2) When the single nozzle arrangement is applied to spray printing of multiple colors or materials, the nozzles often need to be cleaned when the colors or materials are switched to ensure that the materials are completely replaced, resulting in long downtime in the printing process and low production efficiency.
3) Because the spraying of each color or material is separately performed, there may be a relatively obvious boundary between colors or materials, it is difficult to achieve a smooth gradation effect, a color mixing effect is poor, and an appearance effect of a printed part is poor, affecting an appearance of a molded product.
2. The multi-nozzle parallel arrangement mode: the spray head comprises a plurality of nozzles arranged side by side in a straight line. In continuous printing control, each nozzle is independently controlled through a system control end, continuous and differentiated high-frequency control of the spraying state of each nozzle is realized through a rapid signal in the dynamic printing process, and in combination with other mechanical movements, the simultaneous spraying of various materials or colors and the simultaneous printing of a plurality of parts are realized, so that the printing device has higher printing efficiency.
However, the following problems still remain with the multi-nozzle side-by-side nozzle design:
there are limitations on nozzle spacing and nozzle size, affecting print fineness: when the multiple nozzles are arranged in parallel, a certain interval is required to be arranged between the adjacent nozzles so as to ensure that the sprayed materials cannot interfere with each other, but the interval can limit the minimum size and the printing resolution of the spray head; furthermore, too large a nozzle pitch may result in loss of detail or failure to meet some fine print requirements.
The printing speed is different, and the quality of a printing part is affected: when the spray heads with the multiple nozzles arranged in parallel are applied to the rotary 3D printing platform, the control frequency and the amplitude of the nozzles close to the center side and the control frequency and the amplitude of the nozzles far away from the center side may be different, so that the printing speeds of the different nozzles are different, and quality inconsistency or color/material distribution inconsistency among printing components can be caused, and the printing forming quality is affected.
The control system has the advantages of high design difficulty, high control precision and high requirements on spray head debugging and calibration: each nozzle is correspondingly set with different control amplitudes and frequencies to make up the linear speed difference of the inner and outer ring nozzles in circular motion, and the control system is required to be accurately designed, and a great amount of work and time are spent for adjusting and calibrating the system to achieve the expected printing result.
In addition, in the moving printing process of the nozzles, because the nozzles are continuously printed, the operation parameters of the nozzles are required to be controlled at high frequency in real time according to the moving speed, each nozzle is rapidly controlled by continuous and independent instructions, the switching control response of spraying or non-spraying is continuously carried out, the control precision requirement of the nozzles is very high, the switching frequency of the control instructions is very high, the control algorithm is very complex, and the debugging and calibration requirements of the spray heads are very accurate.
Maintenance and cleaning difficulties: because of the complexity of control and high precision requirement, when the nozzle is used for switching the spraying frequency, the amplitude and the like at high frequency, once parameter deviation occurs, blockage and material residue are extremely easy to occur, and the maintenance and cleaning frequency of the nozzle is increased. Moreover, when color or material needs to be changed, it is also necessary to ensure that switching and cleaning are accomplished simultaneously for a plurality of nozzles, which is very cumbersome to maintain and clean.
