The Food and Drug Administration has issued guidelines for 3D medical devices, which means it is one step nearer to becoming an accepted part of the system.
The US agency rules food and drugs with an iron fist and its guidelines are fundamentally the bible for the respective industries. You can’t do anything in America without the organisation’s approval and it is now unquestionably warming up to 3D printing.
First drug to be 3D printed
In March it approved epilepsy drug SPRITAM, which utilized 3D printing to turn it into a new coating and structure which allowed it to dissolve swiftly. 3D printing is in addition heavily involved in the production of medical devices and procedures, which the FDA has a hand in. At the time it was hailed as the start of a downloadable medicine revolution.
3D printing has alterd the world of research and has so many applications in healthcare which it’s a case of prioritising and separating out the workload. It has the ability to alter cardiovascular medicine, implants and actually transplants in the end. The Food and Drug Administration embracing the industry is a significant step forward.
The ‘leap-frog’ draft guidance for medical device manufacturers provides advice and technical needments for production and validation of the devices.
FDA recognises value of 3D printing
The FDA has recognised which 3D printing offers a number of advantages to the medical industry and is now keen to put the regulations in place which can let the industry adopt additive printing en masse. It presents its own problems when it comes to validation, but the governing body is keen to find solutions and recognises the worth of 3D printing.
“AM has the advantage of facilitating the creation of anatomically-matched devices and surgical instrumentation by via a patient’s own medical imaging. One other advantage is the ease in fabricating rigorous geometric structures, enabling the creation of engineered porous structures, tortuous internal channels, and internal assist structures which may not be easily possible via traditional (non-additive) making approaches,” the FDA said.
Specific issues with 3D printing equipment
The devices can obviously have to adhere to standard regulations, but 3D printing presents its own issues and the FDA has outlined the needments for the devices to list every component material and the way it lays them down.
“The ratio of recycled to virgin powder can affect melting properties, which affects the energy needed to turn it into consistent bonding between layers, which in turn affects [a device’s] final mechanical properties,”” said the FDA.
Some of the guidelines can need manufacturers to rethink their guidelines and production systemes to adhere to certain regulations. Overall, yet, the industry should welcome these guidelines as a clear take on to bring 3D printing into the medical fold.
At the moment additive printing is on the sidelines, despite breaking new ground every and every day and contributing to a few of the many astonishing medical work of our time.
3D printing goes mainstream
Now it can move out of the theoretical research and experimental surgery shadows and into the mainstream. The FDA appears caning to assist with the system and we can now appear forward to an actually brighter following.
The guidelines don’t cover bioprinting, which is a minefield in itself and one which may store the regulators occupied for years to come. They in addition don’t actually start to address the concept of bioprinting food.
That is the following big movement on the agenda and it is certain to be a regulatory minefield, actually when we have the technical aspects right.
The red tape is all part of the system, yet, and with every document like this we get a step nearer to additive printing becoming the force for great which we all understand it can be.
