Interview with Mei Ogata of JTL America on Testing for 3D Printing

As we transfer from prototyping to manufacturing, testing is turning into increasingly necessary. Essential in qualifying components and supplies, but additionally in establishing QA or growing new supplies, testing in 3D printing is increasing quickly. You may check for mechanical properties or functionally check a component for a selected software. You might need to measure components by means of CMM or 3D scanning or might want them chemically examined. You might have to test in case your shoe sole truly performs properly as a sole or in case your 3D printing filament offers off the improper fumes. Giant polymer corporations typically do this type of factor themselves, however even they don’t do all of their testing in home. For regulatory, compliance or belief causes as properly it’s typically higher to show to an unbiased testing lab. A kind of is JTL America, which focuses on testing for orthopedics, automotive and aerospace components. The agency has seen a rise in its 3D printing enterprise and we determined to interview Mei Ogata and Kevin Knight of JTL America to be taught extra about testing for 3D printing.

A CT scanner enables you to see into a component. In metallic 3D printed components for instance CT scanners can be utilized to see if the half has inner cracks.

What’s JTL?

Mei: JTL America is an ISO 17025 accredited testing laboratory situated in Fort Wayne, Indiana and Livonia, Michigan. JTL focuses on mechanical testing, vibration testing, and inspection by X-ray CT scanning and 3D scanning.

Why is testing necessary in 3D printing?

Every 3D printing machine has particular tolerances and 3D printed merchandise might deviate from the precise supposed dimensions. 

Dimensional inspection by 3D scanning will present colormaps overlaying the CAD mannequin and the scanned components to visualise the deviation. As well as, deviation labels and varied profile measurement can be found.

Mechanical testing resembling fatigue, tensile, shear and compression testing will assist perceive and characterize 3D-printed materials habits. 

The article, CT Scanning Proves to be an Efficient Technique for Qualifying 3D Printed Elements) talks in regards to the significance of the CT scanning for additive manufactured components.

JTL America gives X-ray 2D scanning and 3D CT scanning along with 3D floor scanning.

Mechanical testing of Orthopedic gadgets at JTL America

What forms of prospects do you want to work for in our trade?

We primarily work for the Automotive, Aerospace and Orthopedic trade.

Within the Orthopedic trade 3D printed implants are gaining reputation for 2 crucial causes. First, 3D printed implants will be designed and printed to match affected person anatomy, eliminating the necessity to take away wholesome bone. In conventional orthopedic surgical procedure, the affected person bone is reduce or drilled to specs outlined by the implant design. When 3D printing is used, affected person CT knowledge is used to design the implant, preserving wholesome bone which ends up in higher bone development, smaller incisions, and sooner therapeutic time. Secondly, 3D printing permits implants to be printed with geometries that aren’t attainable utilizing conventional manufacturing strategies. Specifically, the porous trabecular construction of bone will be approximated utilizing 3D printing. In complete joint alternative specifically, it will be important that the implant has a roughened, and ideally porous, construction to which new bone can connect and mechanically anchor itself. This course of, known as osseointegration, ensures that the implant will likely be properly fixated within the affected person bone as a way to assist the forces of day by day residing. Implants resembling acetabular shells and tibial baseplates utilized in complete hip and complete knee replacements can now be printed with a very porous construction and any thickness because of 3D printing applied sciences.

What companies might you present?

We will supply quite a lot of completely different testing companies however the most well-liked are:

3D Scanning and dimensional inspectionMechanical testing 

JTL will carry out 3D scanning of 3D printed components, then import the CAD mannequin to the scanned knowledge to overlay. As soon as a colormap is created, deviation labels are positioned at related inspection areas. Additionally it is attainable to overly parts-to-parts to investigate the consistency.

Mechanical testing at JTL America

Why would I outsource testing?

JTL America is a crew of certified check engineers who’ve the know-how from the years of its expertise and has efficiently accomplished many tasks. Having JTL as a trusted testing accomplice will deliver value effectivity, scale back time to market and make sure the high quality. 

Utilizing an unbiased and accredited testing laboratory add credibility and accountability to the testing outcomes.

For a remaining components producer what sort of testing can be attention-grabbing?

3D scanning

X-ray scanning to test inside construction

Mechanical testing


Is it tough to check in 3D printing?

No. There’s not a lot distinction with different manufactured merchandise. Mechanical testing of 3D printed components is just like printing historically manufactured components.

Why is testing necessary to orthopedics?

Kevin: Testing is necessary for orthopaedic implants. The FDA and regulatory companies worldwide require that mechanical assessments are carried out on implant techniques previous to approval to be used. Apart from regulatory necessities, mechanical testing is necessary as a result of it gives an evaluation of the implants’ potential to resist the forces generated throughout actions of day by day life.

What can occur if I don’t do it?

If orthopedic implants should not examined, the chance of failure as soon as implanted is elevated as a result of the mechanical integrity of the implant has not been evaluated.
