Lifeink® 200 Kit

Catalog Number: #5202-1KIT

Lifeink® 200 contains 5 mL of highly purified, pH neutral collagen formulated in physiological salts. Cells can be directly added and uniformly mixed in the bioink and then extruded via a 30-gauge needle or larger.

Lifeink® 200 allows for high resolution printing and stable long-term structures when printing into the FRESH support slurry.

Price: $230

3D Printed Lattice

eGFP expressing chondrocytes were encapsulated within Lifeink® 200 and 3D bioprinted. 

Video demonstrates high cell viability after 2 days of cell culture. Images were taken at 10X through approximately 350 um. 

Special thanks to Thomas Kean for the bioprinting work, Danielle MacKay for imaging. We gratefully acknowledge the Integrated Microscopy Core at Baylor College of Medicine for equipment use and the Rolanette and Berdon Lawrence Bone Disease Program for funding.

Lifeink® 200 Shear Thinning and Recovery

A sample of Lifeink® 200 was tested on a Bohlin rheometer with gradually increasing strain for 5 minutes. The sample was then immediately rested, a total of 4 times. Results indicate that Lifeink® 200 demonstrates the unique properties of both shear thinning, and recovering.

Lifeink® 200 Kinetic Gel Stiffness

Lifeink® 200 undergoes an increase in gel stiffness upon incubation at 37°C for >10 minutes. This helps further crosslink and solidify printed constructs.

Lifeink® 200 Flex Test

Constructs printed with Lifeink® 200 act like real tissues. Watch how this printed net will flex like a tissue, and then recover to its original shape once the stimuli is removed.

Lifeink® 200 Frequently Asked Questions

Can I print Lifeink® 200 with the FRESH method?

We highly recommend using the FRESH method to print Lifeink® 200. It gives you the ability to print high resolution, complex structures or tissues, without having to fill your ink with non-native materials (such as alginate or cellulose).

Is Lifeink® 200 really only collagen?

Yes! Lifeink® 200 is a 35 mg/ml concentration collagen bioink, comprised of ~97% type I and ~3% type III collagen.

Can I mix or add other materials with Lifeink® 200?

Yes! The Directions for Use document provides videos showing how to mix in media, proteins, or cells with Lifeink® 200.

Is Lifeink® 200 photocrosslinkable?

Contact us at to discuss possible options.

After printing in FRESH, how do I culture my collagen tissue?

After the print is complete, simply incubate your dish containing the FRESH slurry/encapsulated printed construct at 37°C. The FRESH gelatin microparticles will melt, and your collagen will polymerize. Once the collagen structure is released and floating in the melted gelatin, simply replace the gelatin with warm cell culture media. For example, pipette out 2 mL of melted slurry and replace with 2 mL of media. Repeat until the gelatin is fully washed out.

Need Basic Printing Parameters to Get Started?

Use these parameters as a starting point. Individual printers and bioink formulations (ie. protein concentration, cell density/volume, etc..) will require modified parameters. Hover over a printer to see our recommended print settings.
