# Study of the recycling of metal powders in the laboratory

## You wish to carry out a study on the recycling of metal powders

### Why conduct a powder metal recycling study?

Firstly, in additive manufacturing, whatever the technique used, the management of metal powders rejected during the process is a **key issue**. They cannot be reused immediately, as they are **physically modified and can alter the quality** of the next printed product

It is therefore necessary to requalify them to ensure their recycling, without this leading to excessive costs, contamination of the powders or a loss of quality in the products manufactured. 

Thus, it is necessary to carry out a **complete characterisation of the rejected metal powders** in order to study their recycling. 

Therefore, the support of a **competent metal powder analysis laboratory** is essential for the study of metal powder recycling. 

## FILAB helps you to study the recycling of metal powders

## Instruments for the analysis of metal powders :

- **GranuHeap:** measurement of the static properties of a metal powder (angle of repose, static cohesion index).
- **GranuDrum:** measurement of flow properties (flow angle, dynamic cohesion index, angle of first avalanche, powder aeration).
- **GranuPack:** measurement of the dynamic compaction of a metal powder (apparent density, tap density, Hausner ratio, densification dynamics).
- **GranuFlow:** measurement of flow through orifices, a key indicator of powder flowability.
- **GranuCharge:** measurement of the electrostatic properties of metal powders.

**The FILAB laboratory is accredited ISO 17025 by the COFRAC for:**

- **specific surface measurement using the BET method (in accordance with ISO 9277) and laser particle size analysis (in accordance with ISO 13320 for liquid and dry analysis),**
- **density measurement using Helium pycnometry (in accordance with ASTM B923 and ISO 12154),**
- **grain size determination (in accordance with ASTM E112 and NF EN ISO 643) for solids.**
