Definitions
- the present invention relates to a 3D printing apparatus and method using a support composition containing a curing agent.
- 3D printing is a method of manufacturing structures by stacking materials. It has high precision and degree of structural freedom and can implement various shapes, opening the era of personalized production in new food, medical, and bio business fields. is rapidly emerging as a precision machining technology in In particular, 3D printing in these fields is not 3D printing using existing inorganic/organic materials, but a hydrogel through various biopolymer (gelatin, collagen, gellan gum, xanthan gum, cellulose, alginate, chitosan, etc.) solutions. Utilizing biocompatibility, biodegradability, and mechanical properties, it is being used in applied research for the development of artificial tissues and organs, medical implants, drug delivery systems, and future foods.
- a method of controlling the curing to proceed simultaneously with the output or introducing a material having a strong shape retention power is used.
- a biopolymer such as methacrylic oxide gelatin (GelMA).
- Methacrylic oxide gelatin GelMA
- this method there is an advantage that various shapes can be produced through instantaneous curing, but a separate 3D printing equipment for optical crosslinking such as a stereolithography printer is required.
- due to the inherent cytotoxicity of compounds such as an acryl group and a photoinitiator used for photocrosslinking there are limitations in biotechnological and medical applications.
- Another method is to mix a biopolymer having plastic properties with an additive having Bingham plastic properties to make the biopolymer have shape retention. Relatively various types of output are possible, and there are advantages in that cytotoxic substances such as photocrosslinking are not used. However, there are disadvantages in that the physical and chemical properties inherent in the biopolymer ink, which is a composition forming a structure, change due to the additive, or that biocompatible and cell compatibility is not satisfied.
- bio-ink with plastic properties can be implemented in a free-form form without chemical modification or additional introduction of other materials while maintaining its original material properties. Printing technology is required.
- the present invention provides a 3D printing apparatus and method using a support composition containing a curing agent.
- a 3D printing apparatus using a support composition containing a curing agent includes a support housing accommodating a support composition, a support nozzle provided under the support housing, and the support composition discharged to a platform through the support nozzle a support discharging part including a support dispenser for controlling the flow rate of the; a structure housing for accommodating the structure, a structure nozzle provided under the structure housing, and a structure discharge part comprising a structure dispenser for controlling the flow rate of the structure discharged to the platform through the structure nozzle; and a control unit for controlling the structure dispenser and the support dispenser, wherein the support composition may contain a curing agent for curing the structure.
- the curing agent may be diffused from the support composition to the structure.
- the control unit may control the support dispenser so that the support composition has an accommodation space capable of accommodating the structure to discharge the support composition to the platform.
- the control unit may control the structure dispenser to discharge the structure into the accommodation space.
- the support composition may be Bingham plastic.
