New technology ! Efficient control of your Additive Manufacturing process
Compliant sensors for inline layer-by-layer inspection of 3d printed parts
The control, monitoring, and certification of the quality of the produced parts in Additive Manufacturing still present significant challenges that have to be overcome for a wider use of the technique. Citing the New York Times “But it’s not game over for traditional manufacturing. There are still challenges to additive manufacturing, like ensuring quality control. For instance, is a part reliable if there is a momentary fluctuation in laser power? How much of a fluctuation is OK? Standards and test methods have to be developed, which is difficult because 3-D printing is rapidly evolving and it’s hard for test methodology to keep up.”
Machine agnostic monitoring device
The startup AMiquam provides in-situ solutions to assess the quality of metal parts manufactured by powder bed fusion. Our unique autonomous electromagnetic systems deliver compliant information on the presence of defects and porosity.
The information is collected layer by layer without affecting the machine productivity. We equip most of the additive manufacturing machines in the market with minimal impact and no wire interfaces. The product has been used with Al and Ti alloys as well as stainless steel, constantly increasing the number of materials used in metal AM. The data can also be used by third parties to generate NDT reports remotely. These reports are based on established ASMT and ISO standards and will save post processing inspection costs.
Our monitoring device delivers the typical data shown hereafter. This cross-section side view is collected in-situ, layer-by-layer, and in real time. This is an example of four 316L samples with different laser scan speeds (100% refers to the optimal speed). Varying the scan speed causes defects and inhomogeneities to appear as red spots in the image. Our monitoring device delivers the typical data shown hereafter.

- AMiquam device supports the qualification phase by offering compliant documentation, saving qualification costs and destrutive tests.
- AMiquam monitoring system can be used during the production phase to detect process deviations.
- The data provided can be used by certified inspectors to generate certificates.
- The same equipment can be turned into the optimization mode to quickly find the parameters window corresponding to the lowest porosity or highest production efficiency.
- The hardware platform can be customized to integrate your sensors.
