Invest in Bioprinting to Get a 3D Printed Ear or New Hip: 3D Printing Conference (Part 3)

Cornell Prof 3D Prints Human Ear

Business Cases for Medical 3D Printing, or Bioprinting

Two well-respected speakers in the medical 3D printing field presented today at the Inside 3D Printing conference.

Cornell Professor Lawrence J. Bonassar, Ph.D.

Cornell Professor Lawrence J. Bonassar presented about “3D Fabrication Technologies for Tissue Regeneration.” We wrote about Bonassar’s research in February when he published the concept of 3D printing a human ear.

In his presentation, Bonassar provided the crowded conference hall with an overview of the key bioprinting motivations and applications.

There are approximately 5 million surgeries per year in the US to replace damaged tissues. This is a huge market opportunity for synthetic, bioprinted implants. His team is already looking at research such as replacing spinal discs, demonstrated in rats and dogs, or growing organic tissue like a human ear.

During the Q&A, Bonassar was asked: “This is great research, but is there a way to accelerate it into the marketplace?” Bonassar immediately responded, “Yes, money. There are certain applications that are ready today but just need funding.”

Investors, are you listening?

Andy Christensen, Medical Modeling

The next speaker was Andy Christensen, owner of Denver-based Medical Modeling, who presented on “Industrial 3D Printing for Medical Devices.”

Christensen shared a wealth of examples and ideas, as well as practical commercial commentary, “The cost of surgery is roughly $100 per minute. That’s a business case for 3D printed medical implants.”

He described the current status of FDA approvals for polymeric systems made using 3D printing and additive manufacturing technologies. There are instrument components being cleared, dating back to dental implant drill guides 5 to 7 years ago. European regulation has historically been easier but that may not last.

The focus ahead will be on personalized surgery and efficiency. One example he described is virtual surgical planning, where a surgeon and engineer walk through a pre-operation plan together with sophisticated 3D models. This can save time, money, and reduce recovery time.

Very interesting presentation and clearly a growth area for investors to get involved!


3D Printing Advances Dentistry in London at Daewood & Tanner Practice

Daewood Tanner 3D Printing Dentistry

The field of Dentistry is being redefined by 3D printing. As we reported last April, dental labs are increasingly using 3D scanning and 3D printing technologies to provide personalized care.

Daewood & Tanner is a specialist dental practice in London that is pioneering the use of this technology. Andrew Daewood was recently interviewed by the Financial Times.

“3D printing has recently captured the public imagination, but most 3D printers are churning out plastic junk,” says Andrew Dawood. “Dentists have been using 3D printing for 10 years, to make things that really can’t be made in any other way.”

Daewood’s firm creates dental implants using digital scans and 3D printing.

Although conventional manufacturing still produces most implants, an increasing number are being printed, often using a very durable plastic called Peek that can be implanted into the jaw to replace lost bone. “Our experience with the use of technology to assist ‘extreme cases’ enables us to make straightforward treatment even more straightforward, and for many patients, to make possible what was once considered to be impossible,” says Dawood.

Patients for whom implant treatment used not to be feasible, because they did not have enough bone left in their jaw, can now be treated. New technology allows dentists to identify islands of bone into which implants can be placed, using minimally invasive techniques. “People who once might have been told they were untreatable or needed 18 months of carefully staged, arduous reconstructive surgery, are now being treated in hours or even minutes, usually receiving fixed replacement teeth on the day of treatment,” says Dawood.
