Description

Page width printing rapid prototyping device

The present invention relates to a rapid prototyping device, and more particularly to a rapid prototyping device for page width printing.

Rapid Prototyping (RP technology) is developed based on the concept of constructing pyramid-like layer stacking. The main technical feature is the rapid molding, which can be used without any tools, molds and fixtures. Automatically and quickly convert any complex shape design into a 3D solid model, which greatly shortens the development cycle of new products and reduces R&D costs. It can ensure the time-to-market of new products and the success rate of new product development. Technology provides a more complete and convenient product design communication tool between technicians and non-technical personnel such as technicians and corporate decision makers, product users, etc., thus significantly improving the competitiveness of products in the market and enterprises. Rapid response to the market.

At present, RP technology has developed a 3D solid model by using jet printing technology combined with the precise positioning technology of the carrier. The production method is to first lay a layer of powder on top of the carrier and print on part of the powder by inkjet printing technology. The high-viscosity adhesive allows the glue to adhere to the powder and solidify. The 3D solid model can be completed by repeating the above process layer stacking.

Conventionally, the printing module used in the general scanning reciprocating printing technology is applied to the RP technology. For example, as shown in FIG. 1, the printing module 1 used in the general scanning reciprocating printing technology is disposed on a main body (not shown) for performing a printing operation. The printing module 1 includes a spray The printing platform 10, the carrier 12 and the at least one inkjet head structure 11, the printing platform 10 includes a frame body 101 and a transmission shaft 102 spanning the frame body 101. The carrier 12 is disposed on the transmission shaft 102. The at least one inkjet head structure 11 is correspondingly disposed on the carrier 12, so the carrier 12 and the at least one inkjet head structure 11 disposed thereon can be opposite to the transmission shaft 102 of the printing platform 10. For the Y-axis reciprocating operation.

When the printing module 1 performs the printing operation of the RP technology, the X-axis direction reciprocating is performed through the printing platform 10 with the carrier 12 and the at least one inkjet head structure 11 disposed thereon. Actuated and reciprocated by the ink jet head structure 11 on the carrier 12 along the drive shaft 102 for moving left and right in the Y-axis direction, so that the reciprocating operation is performed through the X-axis and Y-axis directions. The high-viscosity adhesive agent accommodated in the ink jet head structure 11 can be sprayed on a construction material (not shown) on which a construction vehicle (not shown) is laid, and the above process is repeated to carry out layer stacking. The work, in turn, completes the solid model of the 3D object (not shown).

The above-mentioned conventional scanning and reciprocating printing technology uses the printing technology of the printing module to apply to the RP technology to produce a 3D solid model. However, it can be known from the foregoing description that this method still needs multiple axes in the molding speed. (and the X-axis and Y-axis) are mutually displaced to the construction material laid on the construction vehicle to carry out the printing operation. Even if 2~4 layers can be printed every minute, when forming larger objects, this does not stop each other. The staggered displacement time takes several hours or even longer to form.

In addition, the conventional printing scanning technology of the printing module used in the reciprocating printing technology is applied to the RP technology to produce a 3D solid model. On the RP technology implementation device, the volume size of the construction chamber is often considered. The ink jet head structure of the printing module can scan the reciprocating optimum precision stroke, so the size of the construction chamber of the solid model to be molded into 3D is also limited.

Therefore, as far as the rapid prototyping equipment industry is concerned, the technical bottleneck faced by it is the molding speed problem. How to improve these problems is a major problem that the industry needs to solve urgently.

In view of this, how to develop a molding device with a high molding speed is an urgent problem to be solved.

The main purpose of the present invention is to provide a rapid prototyping device for page width printing, which solves the problem that the conventional scanning reciprocating printing technology is used to perform rapid prototyping, which causes slow molding speed and limited size of 3D solid model. And the use of a wide-format printing module with appropriate size requirements to configure a large-sized construction chamber design to complete the formation of a larger-sized 3D solid model.

In order to achieve the above object, a broader aspect of the present invention is a page width printing rapid prototyping apparatus comprising: a construction platform having a construction chamber, wherein the construction chamber has a length of 3.0 m to 5.0 m, The width is 3.0m to 5.0m, and the height is 2.0m to 3.0m; a construction displacement platform is constructed on the construction platform; a one-page wide printing module is constructed on the construction displacement platform, and is linked to the construction displacement The platform performs a reciprocating displacement, and the plurality of inkjet head structures are assembled on the page wide printing module to implement a rapid forming page width printing operation.

The arrangement of the above-mentioned inkjet wafers 201a, 201a' is also considered to match the size of the optimally constructed chamber 222 and maintain the resolution of higher printing quality, and some configuration designs are considered to complete the formation of a large-sized 3D solid model. Rapid prototyping device for page width printing. In an embodiment, the volume of the construction chamber 222 is: 3.0m to 5.0m in length, 3.0m to 5.0m in width, and 2.0m to 3.0m in height. The inkjet wafer 201a, The length of 201a' will be between 2 inches and 2.25 inches, and at least one row of parallel and longitudinal misalignment portions of each of the wide printing units 200, 200' will be arranged to overlap the plurality of inkjet wafers 201a, 201a'. The number of the ink-jet wafers 201a, 201a' is 62 to 117, and the number of the ink-jet wafers 201a, 201a' is preferably 50 to 100. Designed to achieve the best print quality and print speed.

When the page width printing module 20 performs a rapid forming page width printing operation, the page width printing module 20 is relatively displaced relative to the construction platform 22, that is, it can be printed by the page width printing module. 20 is parallelly displaced in the direction indicated by the arrow X1 in Fig. 3A, thereby making the page wide printing The module 20 is moved over the construction chamber 222 of the construction platform 22, and a rapid forming page width printing operation is performed in the construction chamber 222. At this time, since the page width printing module 20 is constituted by the arrangement of the plurality of ink jet head structures 201, the total length W of the ink jet head structures 201 spans greater than or equal to the width S of the construction chamber 222. Therefore, when the page wide printing module 20 performs the rapid forming page width printing operation, it only needs to be displaced in a single X-axis direction, and the displacement in the Y-axis direction is not required, so that the spraying can be accelerated. Printing speed and efficiency.

Of course, the relative movement of the page width printing module 20 and the construction platform 22 is not limited thereto. For example, the construction platform 22 may be opposite to the page width printing module 20 by Parallel displacement in the direction indicated by the X2 arrow in FIG. 3A, so that the construction platform 22 drives the construction chamber 222 to move relative to the page width printing module 20, and the page width printing module 20 corresponds to a page width printing operation in the construction chamber 222 for rapid prototyping. In addition, the page width printing module 20 and the construction platform 22 may be relatively displaced in the direction indicated by the X1 and X2 arrows, respectively, so that the page width printing module 20 moves. To the top of the construction chamber 222 of the construction platform 22, a rapid forming page width printing operation is performed in the construction chamber 222. It can be seen from the foregoing various embodiments that whether the page wide printing module 20 or the construction platform 22 is separately displaced, or both are relatively displaced at the same time, they only need to be displaced in a single X-axis direction. , the rapid-formation page wide printing operation can be achieved, which can omit another (Y-axis) direction displacement operation compared with the conventional rapid prototyping printing operation, so the rapid prototyping page wide spray of the present invention Printing operations can speed up the printing speed and improve the printing efficiency.

In summary, the page wide-printing rapid prototyping device of the present invention performs rapid prototyping wide-width printing in the construction chamber by a page width printing module that can be relatively displaced with the construction platform and its construction chamber. The job can be used to greatly increase the forming speed and molding efficiency through this rapid prototyping wide-width printing operation.
