Technical field

The present invention relates to 3D printing technique field, in particular to a kind of DLP3D Method of printing for intersecting grid.

Background technique

DLP forming technique is the abbreviation of " Digital Light Processing ", and as digital light processing also belongs to 3D One of manufacturing technology is printed, which is first layered mathematical model by a direction, according to every layer of data Then information is solidified by the light source of specific band using specific photosensitive resin material, successively accumulates, be layering, most A physical item is formed afterwards.

Because size is different when present DLP molding, the heat released is also different.Because of usually chemical reaction temperature Every 10 DEG C of raising is spent, reaction speed increases about 2~4 times.To cause curing time different, the layer of large area is caused to be easy Overreaction, it is insufficient that the layer of small area is easy reaction.In order to compensate its defect, the DLP3D for developing a kind of intersection grid is beaten Impression method.

Summary of the invention

The technical problem to be solved in the present invention is to provide it is a kind of be able to solve printing when because reaction generate temperature difference beat Print the DLP3D Method of printing of the intersection grid of effect different problems.

In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:

A kind of DLP3D Method of printing intersecting grid, includes the following steps:

(1) profile for obtaining model first layer, is filled in first layer profile using honeycomb structure；

(2) first the honeycomb structure in the first layer profile of model and first layer profile is printed, then to first layer Honeycomb interior zone in profile is printed；

(3) profile for obtaining the model second layer, is filled in second layer profile using honeycomb structure；

(4) honeycomb structure in the second layer profile of model and second layer profile is printed, then to second layer wheel Honeycomb interior zone in exterior feature is printed；

(5) honeycomb structure is alternately filled according to first layer and the second layer fill method when succeeding layer prints.

Preferably, the honeycomb structure in adjacent two layers profile is not overlapped.

Preferably, the profile thickness is 1~10mm.

Preferably, the honeycomb structure is regular hexagon.

Preferably, the honeycomb structure side length is 1~10mm.

By adopting the above technical scheme, the present invention, which uses, first prints honeycomb, then to the method that inside is filled, beats The model of print has high-precision and high intensity, and effectively reduces model warpage；The present invention uses and first prints honeycomb, then right The method that inside is filled, the case where capable of effectively reducing over-curing in print procedure.

Detailed description of the invention

Fig. 1 is the arrangement signal of the honeycomb structure in first layer profile of the invention and the honeycomb structure in second layer profile Figure.

Specific embodiment

Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
