3D printed biomaterials for bone tissue engineering

Posted by in categories: 3D printing, bioengineering, bioprinting, biotech/medical, life extension

When skeletal defects are unable to heal on their own, bone tissue engineering (BTE), a developing field in orthopedics can combine materials science, tissue engineering and regenerative medicine to facilitate bone repair. Materials scientists aim to engineer an ideal biomaterial that can mimic natural bone with cost-effective manufacturing techniques to provide a framework that offers support and biodegrades as new bone forms. Since applications in BTE to restore large bone defects are yet to cross over from the laboratory bench to clinical practice, the field is active with burgeoning research efforts and pioneering technology.

Cost-effective three-dimensional (3D) printing (additive manufacturing) combines economical techniques to create scaffolds with bioinks. Bioengineers at the Pennsylvania State University recently developed a composite ink made of three materials to 3D print porous, -like constructs. The core materials, polycaprolactone (PCL) and poly (D, L-lactic-co-glycolide) acid (PLGA), are two of the most commonly used synthetic, biocompatible biomaterials in BTE. Now published in the Journal of Materials Research, the materials showed biologically favorable interactions in the laboratory, followed by positive outcomes of in an animal model in vivo.

Since bone is a complex structure, Moncal et al. developed a bioink made of biocompatible PCL, PLGA and hydroxyapatite (HAps) particles, combining the properties of bone-like mechanical strength, biodegradation and guided reparative growth (osteoconduction) for assisted natural bone repair. They then engineered a new custom-designed mechanical extrusion system, which was mounted on the Multi-Arm Bioprinter (MABP), previously developed by the same group, to manufacture the 3D constructs.

Allevi, Made in Space team up to develop first 3D bioprinter in space

Posted by in categories: 3D printing, bioprinting, education, space

3D bioprinting company Allevi has teamed up with California-based 3D printing and space technology firm Made In Space to develop the Allevi ZeroG – the first 3D bioprinter capable of working in low-gravity conditions.

Allevi (formerly BioBots) was founded in 2014 by University of Pennsylvania graduates Ricardo Solorzano and Daniel Cabrera. At the time, the ambitious duo set out to develop an accessible desktop bioprinting system which could be used for a wide variety of research and educational applications.

Russian scientists 3D printing biological tissues with magnets in microgravity

Posted by in categories: 3D printing, bioprinting, biotech/medical, nanotechnology

3D bioprinting is a process for patterning and assembling complex functional living architectures in a gradient fashion. Generally, 3D bioprinting utilizes the layer-by-layer method to deposit materials known as bioinks to create tissue-like structures. Several 3D bioprinting techniques have been developed over the last decade, for example, magnetic bioprinting, a method that employs biocompatible magnetic nanoparticles to print cells into 3D structures.

But now a Russian research team has developed a new method of bioprinting that allows to create 3D biological objects without the use of layer-by-layer approach and magnetic labels. The new method, which involves magnetic levitation research in conditions of microgravity, was conducted by the 3D Bioprinting Solutions company in collaboration with other Russian and foreign scientists, including the Joint Institute for High Temperatures of the Russian Academy of Sciences (JIHT RAS).

Bioprinting is the next medical revolution — C2 Montreal

Posted by in categories: bioengineering, bioprinting, biotech/medical

Erik Gatenholm is Co-Founder and CEO here at CELLINK. In 2017, he founded CELLINK to revolutionize the way that we conduct medical research worldwide. He led a workshop at the C2 Montreal conference called “Need a tissue, Bioprinting is the next Medical Revolution”

At C2 Montreal – There was a presentation on bioprinting and Cellink technology. Then there was an activity where people in groups looked at a sample of bioprinted tissue and people worked on exercises of what people thought was possible or preposterous in the future.

New DIY 3D Bioprinter to Create Living Human Organs

Posted by in categories: 3D printing, bioprinting, biotech/medical, engineering, life extension

DIYers can bioprint living human organs by modifying an off-the-shelf 3D printer costing about $500, announce researchers who published the plans as open source, enabling anyone to build their own system. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Scientists at Carnegie Mellon University (CMU) developed a low-cost 3D bioprinter to print living tissue by modifying a standard desktop 3D printer and released the design as open source so that anyone can build their own system.
