Scientists Successfully 3D Print A Human Heart Tissue


A team of scientists at a Chicago based bio startup BIOLIFE4D has announced a major breakthrough after they successfully 3D printed a human cardiac tissue. The scientific milestone was achieved after the opening of the company’s new research facility in Houston. The printing of the human cardiac tissue involves multiple cells which form the human heart. Bioprinted cardiac patches can be used in patients with serious heart failures to restore the lost myocardial contractility.

The company is planning to turn its focus to other parts like valves, blood vessels, and a mini-heart since it involves 3D bioprinting a full human heart. Chief Science Officer of BIOLIFE4D Birla said, We are extremely excited to have achieved this milestone and to successfully demonstrate our ability to 3D print human cardiac tissue. When we began this process, we knew this would be a key step in validating our technology and scientific approach, so we are pleased to be able to have accomplished this so quickly.”

CEO of BIOLIFE4D Moris said that there are other companies which have made similar patches but none of them have included each of the cell types which make up the heart. This tissue also had vascularization which is needed to allow the body to nourish the cells and remove the waste products. He said, You can think of it like this is the first time all of the proper ingredients were used to properly make the recipe.”

BIOLIFE4D’s innovative 3D bioprinting process will provide the ability to reprogram a patient’s own blood cells. Induced Pluripotent Stem Cells (iPSCs) are a type of pluripotent stem cells that can be generated directly from the adult cells. The iPS cells are then differentiated into different types of cardiac cells needed to 3D bio-print not only a cardiac patch but ultimately a human heart viable for transplant as well. This implies that the 3D printed heart by BIOLIFE4D uses cardiac cells which are derived from their own iPS cells to create a living viable construct.
Fingers crossed for this new technology!

3D Printed Gun Files Can Be Shared Without Legal Penalty

Liberator Pistol 3D Gun

Sharing files that can help anyone 3D print guns is now legal and protected under free speech.

That’s the key takeaway from a major settlement between the US government and gun rights activist Cody Wilson in his attempts to distribute 3D-printed firearms.

On Tuesday, his legal team announced the settlement, calling it a “devastating blow” to the gun control lobby. “I consider it a truly grand thing,” Wilson told Wired in an interview. “It will be an irrevocable part of political life that guns are downloadable and we helped to do that.”

Cody Wilson

Back in 2013, Wilson began uploading 3D printable CAD files to create a working plastic gun, called the “Liberator.” This drew the attention of federal authorities; the US State Department demanded Wilson pull down the files, claiming he was violating an export rule on distributing secret military hardware.

In response, Wilson eventually took the US government to court; he’s been arguing that the First Amendment protects his constitutional right to share the 3D files as free speech.

The legal battle has gone on for three years. But according to Wired, two months ago, the Justice Department decided to quietly offer Wilson a settlement to end his lawsuit. Under terms of the deal, the US government has agreed to change its export rules on military firearms, allowing Wilson to publish his 3D files, without fear of legal penalty.

“Significantly, the government expressly acknowledges that non-automatic firearms up to .50-caliber — including modern semi-auto sporting rifles such as the popular AR-15 and similar firearms — are not inherently military,” said the Second Amendment Foundation, which supported Wilson in his lawsuit.

So far, the Justice Department hasn’t commented on the lawsuit, but the settlement opens the door for the proliferation of 3D printed guns. Wilson has started his own nonprofit, called Defense Distributed, which is seeking to become a digital warehouse for open source gun designs. (His nonprofit is also offering a 3D printer for $1,675 that can fabricate a metallic lower receiver to an AR-15 rifle.)

However, gun control advocates will no doubt oppose the settlement. Critics worry that as the technology matures it could fall into the wrong hands, and pave the way for untraceable guns that criminals can buy or print for themselves.

Family Ramdani became the first in the world, settled in printed on a 3D printer home. Its construction cost of $233 thousand

House of 95 m2 printed a little more than two days. To live in a family of five – parents and three children. Ramdani the first people in the world who decided to settle in this building.

Print four-bedroom house took two days. And the creation of roofs, Windows and doors took another four months. The developers claim that in the future the same house can be reprinted several times, and then construction will go a day and a half.

The aim of the architects was to make the construction process not only faster, but cheaper, and they achieved it. The family home of Ramdenic cost nearly $233 thousand, which is 20% less than when using conventional building technologies. Impressive, isn’t it?

This house was created in collaboration between Nantes University, city Council and the housing Association. The leading innovator of the city Council, Frankie, Tricia (Francky Trichet) said that the main goal of this project was to determine whether 3D printing to become a key building solution to apply to different types of communal buildings. Trichet believes that this concept can affect urban development as a whole.

The family home of Ramdane was designed by a team of scientists and architects, after which their work began and a 3D printer. He printed layers of walls from floor to ceiling. Builders had only to insert Windows and doors and do the roof.
