Embodiment Construction

[0040] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] The parametric design method of the 3D printing protective mask of the present invention specifically includes the following steps: Step 1, the size classification and definition of key parts of the face (as shown in Figure 1, Figure 1 (a) is a facial feature diagram on the side of the human body; Figure 1 (b) ) is the frontal facial feature map of the human body): In Figure 1(a), A: frontal vertex, B: nasal root point, C: nasal tip point, D: subnasal point, E: submental point; in Figure 1(b) , F: left frontal vertex, G: right frontal vertex, H: left zygomatic point, I: right zygomatic point, J: left nasal alar point, K: right nasal alar point, L: left mandibular angle, M: right mandibular angle; Figure In 1(a), h1: frontal face length, h2: nose height, h3: morphological face length; w1: nose depth; in Figure 1(b), w2: minimum forehead w...

Abstract

The invention discloses a parameterization design method for a 3D printing protective mask. The parameterization design method specifically comprises the following steps that 1, size classification is conducted on key parts of the face of a human body; step 2, dividing facial feature positioning points according to a size classification result in the step 1; step 3, collecting facial feature data; step 4, determining a positioning point according to the data received in the step 3; 5, capturing a curve of a key part of the human face according to the position of the positioning point determined in the step 4; 6, drawing a curve of the sealing part of the protective mask; and 7, constructing a three-dimensional model of the protective mask. The method is short in design period, and the designed protective mask is good in protective tightness.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a parametric design method for a 3D printing protective face shield. Background technique [0002] A protective mask is generally a device composed of breathing valves, protective cotton sheets, masks and other components to protect the face from flying metal debris, harmful gases, liquid splashes, metals and high-temperature solvent flying dust. The existing protective masks can play a protective role well, but there are still the following deficiencies: (1) The preparation method of general protective masks adopts mold-opening processing and production, but the mold-opening process is relatively complicated, and the production of molds It is more complicated and difficult, the production process is complex and diverse, the production cycle is long, and the production cost is high; (2) It is not friendly enough to special working groups and cannot meet the individual needs of ...
