A method for making in-situ 3D printed custom masks based on facial feature extraction

Abstract

A method for producing an in-situ 3D printing custom mask based on facial feature extraction, belonging to the field of 3D printing technology and medical protective gear. The present invention uses software such as SolidWorks, Magics, etc. to design and optimize the mask model, and ANSYS finite element simulation is used to verify whether the comprehensive performance of the designed model reaches the expectation, and the final optimized part outside the mask at a position of 2 cm perpendicular to the face direction is processed by molds, Place the processed part of the mask that is 2cm perpendicular to the face direction at the bottom of the FDM 3D printing device. On this basis, in-situ 3D print the part of the mask that is close to the face within 2cm perpendicular to the face direction. The mask after printing is completed. After a series of post-processing, the real object finally gets an in-situ 3D printed personalized mask based on facial feature extraction with excellent mechanical properties, excellent mechanical properties, light weight and comfort.

Description

technical field [0001] The invention relates to a method for making an in-situ printed mask by combining traditional mold processing methods with 3D printing technology, belonging to the fields of traditional machining, additive manufacturing and medical protective gear. The main body of the mask is processed by traditional molds. The mask part near the face uses FDM technology to prepare an in-situ 3D printing customized mask according to the characteristics of the face. The combination of the two methods can not only solve the problem that the 3D printing time period is too long, but also meet the high cost of traditional processing and personalized customization. Background technique [0002] Although traditional masks provide good protection for our front-line personnel in function, there are still many shortcomings that can be improved. For example, the tightness is not strong and so on. The advantages of using the mold-processing production method of masks are that t...

Problems solved by technology

[0002] Although the traditional masks have given our front-line personnel good protection in terms of function, there are still many shortcomings that can be improved

For example, the sealing is not strong, etc.

The advantage of the production method of mold processing is that the production cycle is short and the cost is the lowest. It only takes one to two days to make a full-page mold. The disadvantage is that the surface of the finished product is rough, and the mold is easy to break during production. It is the mold production that cannot meet the growing individual needs of the people

3D printing has become an important means to solve this problem, but the production cycle of 3D printing is long and the cost is high
