Body anatomical model

for teachingembryoresin

Constructing a multi-structured 3D digital anatomical model from high-precision digitized human body data. Full-color, multi-material 3D printer and environmentally friendly resin material printing, providing 1:1 high simulation of physical anatomical models. Early embryonic stage (1-5 days) Ratio：200：1 1 day old embryo: fertilized egg with outer hyaline band. Blastocyst size: 0.2 mm 2-day-old embryo: 2-cell stage, consisting of two ovoid spheres with outer zona pellucida and 2 to 3 polar bodies visible. Blastocyst size: 0.2mm 3-day-old embryo: mulberry embryo, composed of about 16 ovoid spheres, resembling a mulberry, and covered with a zona pellucida. Blastocyst size: 0.2mm 4-day-old embryo: blastocyst, also known as blastocyst, with the trophectoderm surrounding the blastocyst cavity, with a cluster of inner cells at one end of the cavity and a zona pellucida around the blastocyst. Early embryonic stage (6-14 days) Ratio：50：1 6 days old embryo: onset of implantation: adhesion of the trophoblast end of the blastocyst to the endometrium. Embryo blastocyst size: 0.25mm 7-day-old embryo: embryo in implantation, blastocyst partially enters the endometrium and the trophectoderm differentiates into the cytotrophectoderm and the syncytial trophectoderm. Blastocyst size: 0.25mm 9-day-old embryo: The blastocyst penetrates deeply into the endometrium, the implantation opening is sealed by the coagulation plug, the dictyostelium is formed, the amniotic sac and primary yolk sac appear one after another, and the trophectoderm traps appear in the syncytial trophectoderm.
