CollPlant targets formulation bottleneck with new DLP bioprinting equipment

Regenerative drugs specialist CollPlant has launched BioFlex, a ready-to-print bioprinting equipment constructed on rh-collagen, aimed toward researchers engaged on tissue engineering and regenerative drugs.

The equipment is designed for Digital Gentle Processing (DLP) bioprinting and targets two purposes: tissue mannequin biofabrication for drug discovery, and the event of engineered tissues and transplantable organs. It comes with Collink.3D 50, a biodegradable polymer element, and proprietary photoactive brokers optimised for high-resolution DLP printing.

“By integrating our standardized recombinant human collagen with biodegradable polymers and photoactive parts – supported by expert-developed formulation and printing pointers – we allow seamless preparation and extremely reproducible, high-resolution printing outcomes,” mentioned Yehiel Tal, CEO of CollPlant.

Addressing Bioink Formulation Complexity

BioFlex is designed to cut back the element screening and simplify formulation improvement work that routinely slows initiatives down, enabling labs a quicker path to bioinks with adjustable mechanical properties. 

The specialist says customers following the equipment’s formulation and printing pointers can fabricate complicated organic constructions with management over enhanced tensile energy, elasticity, diminished brittleness, and improved structural integrity.

CollPlant says constructs produced with BioFlex reveal enhanced mechanical efficiency and consistency. The corporate additionally describes the equipment as an animal-free various to standard programs, saying the scaffolds it produces are designed to carefully replicate the bodily traits of native human tissues and organs. 

BioFlex is aimed toward educational laboratories and industrial R&D groups working throughout bioprinting, tissue engineering, and regenerative drugs.

Formulation complexity has lengthy been one of many extra cussed sensible limitations in bioprinting analysis. Constructing a dependable bioink system usually requires in depth screening of particular person parts, and small variations in materials properties can compromise the reproducibility of printed constructions. 

Prepared-to-use kits that standardise that course of are comparatively unusual, notably ones constructed on rh-collagen slightly than animal-derived sources, which may introduce variability in bioprinting purposes.

Decreasing Preparation Steps in DLP Bioprinting

Simplifying bioink preparation has change into a recurring design precedence throughout DLP bioprinting, as researchers and producers alike take care of the time and useful resource prices of formulation improvement. A number of current developments mirror that stress.

As an example, CARIMATEC’s ZENESIS system, launched at Formnext 2025, factors to the identical formulation and reproducibility constraints. Its freeze-dried EZ-preBioink capsule is designed to cut back instability related to liquid formulations, providing researchers a ready combine that solely requires combining with tradition medium earlier than printing. 

The South Korean producer constructed the DLP-based system round that precept, focusing on pharmaceutical corporations, college hospitals, and beauty laboratories.

Individually, researchers at Missouri College of Science and Know-how developed a light-driven DLP approach that makes use of a one-pot formulation to cut back the processing steps concerned in creating organs-on-a-chip. 

The strategy combines a sacrificial resin with the fabric forming the ultimate microchannel system in a single formulation, which the crew says accelerates prototyping and testing of tissue-chip designs. The work underlines how formulation complexity stays an energetic space of problem-solving throughout DLP bioprinting analysis.
