The past 30 years have provided major advances in technology. Whether the advances were in the automotive industry or scientific fields, CAD programs have been at the forefront of this innovation. Thanks to CAD developers, 3-D print technology can now be found across multiple industries.
Since the late 1980’s and early 90’s, 3-D printing has become a major part of this technology advancement and as a result, have found a place within the biotechnology field.
How Does 3-D printing Affect Medical Science?
Printing of biomaterial has allowed doctors to treat patients with engineered tissue. Patients who might otherwise die because of lack of donor organs can now look to biotechnology to save their lives. 
Within the past 5 years, the advancement of biotechnology from CAD applications has increased the likelihood of survival in patients with terminal illness.
Advantages of 3-D Bio-printing
- Reduced wait time for organ transplants
- Safe pharmaceutical testing
Challenges of 3-D Bio-printing
- Difficulty creating large organs and tissues
- Transplantation time
Techniques for 3-D Organ Printing
Extrusion-Based – the printing procedure includes a printer head on a motorized axis and a “growth plate.” The bio cells are printed in layers onto a hydrogel template at precise locations, thus creating engineered tissue. A CAD program ensures accuracy in the printing program.
Inkjet Printing – bio cell droplets are produced by air pressure pulses, forcing the droplets from the inkjet nozzle. Each drop fuses on a “growth plate” to create a 3-D structure of tissue. The layering of drops continues the fabrication process.
Laser Based Cell Writing – a laser beam creates a shock in the bio-solution within the hydrogel by an expansion of gasses. The laser heats a glass slide, which causes the air expansion. Once the air bubble begins to form, this pressure pushes the bio-solution away from the glass slide and deposits the material onto a “growth plate” in the proper proportions. Laser printing reduces error in the volume and density of the material being printed resulting in a consistent and precise biomaterial.
