Embryonic stage (3-6 weeks)

"Digihuman Technology" builds a 3D digital anatomical model with multiple structures through high-precision digital human data, and extracts the voxels of the corresponding parts of the digital human data We use a full-color, multi-material 3D printer and environmentally friendly colored resin materials to print high-simulation anatomical specimens. We use a full-color, multi-material 3D printer with environmentally friendly colored resin materials to print high-simulation anatomical specimens in order to provide 1:1 high-simulation physical anatomical models for the severely lacking cadaveric specimens.

Key words

Application Introduction

Embryonic stage (3-6 weeks)


At the end of 3 weeks: evolution of the discoid embryo to the barrel embryo, formation of the cephalic, caudal, and lateral folds, beginning of the closure of the neural groove, 4-8 pairs of somites. Embryonic body length: 2.0mm

Early 4 weeks: barrel-shaped embryo, neural sulcus continues to close, anterior and posterior neural pores visible. Body segments 8-12 pairs.  Embryo body length: 3.5 mm

Mid 4 weeks: the embryo is barrel-shaped, the anterior neural pore is closed, and the posterior neural pore is not yet closed. The 1st, 2nd, and 3rd pairs of gill arches appear. The lens plate and auditory sulcus appear, and the cardiac rongeur and caudal bud are obvious. Body segments 13-21 pairs.   Length of parietal rump: 4.5 mm

At the end of week 4: Both anterior and posterior neuropores were closed, 21-30 pairs of somites, 1st, 2nd, and 3rd pairs of gill arches appeared, upper and lower limb buds appeared successively, anterior cerebral prominence and oral concavity were clearly visible. Length of parietal rump: 5.5 mm

5 weeks: The body segments reach more than 40 pairs, the 4th-gill arch appears, the cardiac ramus is obvious, the upper limb buds are paddle-shaped, and the optic cup and the outer ear primordium appear.  Length of terminal rump: 8.0mm

6 weeks: finger (toe) release lines appear on the hand and foot plates, ear mounds are clearly visible, and physiological umbilical hernia appears. Length of parietal rump: 13mm  


3D Printing
The selected full-color, the multi-material 3D printer was used to print the digital model, which uses 3D inkjet printing technology and light-curing technology with 12 material channels for multi-material combination printing. The chosen 3D printer can realize 3D printing in accordance with a variety of modes such as single hardness material, soft and hard combination material, and transparent wrapped material.

Full-color printing: Multi-channel digital full-color 3D printing technology provides you with unique color configuration options to create dazzling and colorful excellence.

Multi-material printing (with eco-friendly materials): from rubber-like to rigid materials, from transparent to opaque materials, from colorless to colored materials, from standard grade materials to biocompatible materials. Diverse composite 3D printing solutions for printing complex surgical medical models for anatomy teaching, neurosurgery, cardiovascular, oncology, etc.

High-efficiency printing: Up to 3840 piezoelectric holes and featured algorithms for up to 4L per hour through high-frequency jet curing, complemented by efficient post-processing equipment for faster, more accurate printing and no secondary curing.
