Production of Formed Elements

Production of Formed Elements

Hemangioblasts are multipotent stem cells originating from the mesoderm. They give rise to hematopoietic stem cells (HSCs), which undergo hematopoiesis to produce all the formed elements of blood. This process is regulated by a complex network of hematopoietic growth factors, including transcription factors, growth factors, and cytokines. These factors stimulate the HSCs to divide and differentiate, though some HSCs remain undifferentiated to maintain a self-renewing pool.
Most HSCs commit to...

Area of Science:

Materials Science
Engineering
Polymer Chemistry

Background:

Traditional additive manufacturing (3D printing) relies on slow, layer-by-layer fabrication.
Existing methods face limitations in speed and scalability for producing larger objects.

Purpose of the Study:

To develop a novel method for continuous, high-speed 3D printing of polymeric parts.
To achieve high feature resolution and enable the fabrication of centimeter-scale monolithic objects.

Main Methods:

Utilized continuous liquid interface production (CLIP) with an oxygen-permeable window.
Established a "dead zone" of inhibited photopolymerization at the liquid-solid interface.
Controlled critical parameters to enable continuous part extraction.

Main Results:

Demonstrated continuous fabrication of monolithic polymer parts up to tens of centimeters.
Achieved feature resolution below 100 micrometers.
Reached printing speeds of hundreds of millimeters per hour, reducing production time from hours to minutes.

Conclusions:

Continuous liquid interface production offers a significant advancement over traditional 3D printing methods.
This technique enables rapid, high-resolution manufacturing of large-scale polymer objects.
The process holds potential for revolutionizing polymer part fabrication across various industries.
