Additive Manufacturing

The iam-approved.com web store is aimed primarily at small and medium-sized 3D printing service providers facing new challenges, such as proving material properties achieved in production to its clients and customers.

The range of tests for additively manufactured accompanying samples includes all standard test procedures, such as notched bar impact tests according to DIN EN ISO 148-1 as well as tensile tests according to DIN EN ISO 6892-1. Initially, the joint TÜV NORD and Additive Marking web store will start with an initial small selection of tests, which will be successively expanded to include further services for additive manufacturing.

The decisive advantage lies in the automated and unambiguous labeling of the samples at the moment of their creation. This completely eliminates the otherwise time-consuming and error-prone manual marking effort, both on the customer side and later in the test laboratory. This special form of marking is a unique selling point and is only offered by TÜV NORD and Additive Marking.

The serialized and uniquely traceable manufacturing test specimens result in enormous simplifications and acceleration of processes for 3D printing service providers. They get an all-inclusive package, from the provision of the right test specimens to the elimination of manual manufacturing documentation and the digital transmission of test results.

TÜV NORD supports you with a wide range of component testing possibilities for special applications, both destructive and non-destructive (see mechanical/technological tests). Our laboratory offers the full range of non-destructive testing processes. To detect porosities, cracks and similar discontinuities, we will choose the right X-ray technologies for your application. In the high-end range, computer tomography offers excellent opportunities for component analysis and allows a detailed inspection of the interior structures of your 3D-printed part.

TÜV NORD certifies between 20,000 and 25,000 personnel per year in the field of joining technology. Get your personnel qualified in the field of additive manufacture and quality management!

Operator examinations can be based, for example, on DIN 35225 “Welding for aerospace applications – Qualification testing of operators for powder bed based laser beam machines for additive manufacturing” or on DIN EN ISO 14732 “Welding personnel – Qualification testing of welding operators and weld setters for mechanized and automatic welding of metallic materials”.

Certified management systems are the key to market entry and the prerequisite for gaining access to regulated sectors such as aerospace engineering, pressure vessel construction or med-tech. TÜV NORD offers both basic certification of your management systems to DIN EN ISO 9001: 2015 and special certification, for example, for the automotive industry.

Make use of our expertise in rapidly and reliably determining the mechanical and technological properties achieved in manufacture. Our accredited test labs carry out all investigations swiftly, efficiently and to the applicable standards.

Our range of trials for 3D-printed test samples covers all the standard processes, such as:

• Charpy pendulum impact test to DIN EN ISO 148-1
• Tensile test to DIN EN ISO 6892-1

We will be happy to agree in advance on the number and type of test samples to be produced on the side during additive manufacture.

Naturally, we can also offer materials science investigations for your 3D-printed parts, based on the questions you would like answered.

Alongside the comprehensive analysis of your production samples, we also offer tried-and-tested logistics solutions for sample transportation and informative documentation of the test results.

The characteristics of your primary material, alongside the process parameters used in your 3D printer, determine the material properties of the component you manufacture.

But what are the properties of your primary material? Does your metallic powder come up to your requirements? Have your customers’ specifications been met?

Be on the safe side and have TÜV NORD independently analyse the properties of your starting material. Our accredited laboratories will rapidly and reliably analyse your material samples on the basis of a TÜV NORD testing programme. For example, our reliable grain size distribution analyses can provide you with valuable information to help optimise your machine settings. Naturally, we will also inspect the primary material against other current international test specifications.
