ROKIT (or ROKIT Healthcare) is a South Korea-based 3D bioprinting research company that develops hardware, software, and clinical applications employing the 3D printing technology for customized human organ and tissue reconstruction and regeneration. The company, headquarted in Seoul, was established as a subsidiary of 3DISON, which commercializes 3D printers, consumables, and printing services in various areas across industrial manufacturing, design, food, and bioengineering. ROKIT manufactures and markets its internally developed bioprinter line of INVIVO and medical 3D printing kits.

3D bioprinting
Trauamatic injuries, vascular abnormalities, cancer treatment, and malfunctioning organs often involve loss of tissue that, traditionally, could be restored only through surgical transfer of natural tissues from donors. 3D bioprinting is being explored today as an alternative solution to on-demand fabrication of living tissues and organs. The technology works by translation of a digital 3D file into computer-aided manufacturing of a living structure consisting of cells, growth factors, and biomaterials. Most commonly used techniques in bioprinting include traditional material deposition (extrusion or ink-jet), or modern optics-based/laser-assisted polymerization. The technology has already found applications in the clinic, not only as a tool for generating customized surgical guides but for transplantation of tissues made from patients' own stem cells or tissue isolates, including skin, bone, vascular grafts, cartilage, trachael splints, and heart tissue. Other applications include developing high-throughput bioprinted tissue assays, like skin and liver, for cosmetic and drug discovery and testing. Besides optimization of 3D printing mechanics, there is active research in the discovery of novel biodegradable, biocompatible materials that have high material strength (for dental and orthopedic implants) or are readily moldable (for soft tissues like skin and heart tissue) specific to different tissue applications.

History
ROKIT's parent company 3DISON was founded in 2012 by Seok Hwan You as a 3D printing technology company. From 2013 - 2015, the company released several desktop 3D printer lines for applications in educational training, fashion, design, food and industrial manufacturing in aerospace and automobile parts. The products include:


 * Edison S, Multi and Pro: released in 2013, desktop extrusion printers for common thermoplastics like PLA, PCL, HIPS, PVA, and nylon
 * AEP: released in 2014, advanced engineering plastic printer specialized for high-performance functional materials, i.e. PEI and PEEK
 * Chocosketch: released in 2015, food printer specialized for chocolate geared toward food design industries
 * Stealth: released in 2016, three-color multi-material printer

In 2016, the company entered the biomedical 3D printing industry as ROKIT with the launch of INVIVO, with a clean chamber technology of HEPA and sterilizing UV. ROKIT partners with governments, biotechs and academic medical centers to design and develop clinical applications employing 3D printing technology in the operating room. ROKIT won a $3 million grant from the Korean government
