The quality of the base material is crucial for the quality of the final product. To fully utilize the advantages of additive manufacturing, the necessary quality and reliability requirements must also be met. This is achieved through material testing by Alter | HTV. Triple sampling from the powder sample  Evaluation at up to 10 locations per sample (total of 30 locations)  Determination of particle size distribution using a scanning electron microscope (measurement of structures/particles from 0.5 µm possible) Measurement of the equivalent circular diameter/circumscribed circular diameter  Measurement in accordance with DIN ISO 9276 / ISO 13322-1 Determination of median (D50), mean value, D10, and D90 of the particle size distribution Measurement of plastic powder using FTIR spectroscopy Measurement of one IR spectrum and comparison with the Alter | HTV Material identification is only possible if it is listed in the database
