RECIPESLENS® MATERIAL STARTER RECIPESLENS Material Starter Recipes are time saving tools helping customers speed the development of new additive manufacturing
applications. Developed by Optomec LENS application engineers and material scientists, each recipe provides detailed instructions covering powder feedstock characteristics, machine set-up, processing parameters and expected results for a variety ofcommercially available powders. Each recipe is also geometry specific providing time savings guidelines to produce quality
results for thin wall, small volume and large volume structures. Optical and SEM images showing the microstructure and morphology of samples printed using each recipe are provided. Tensile tests conducted by an independent lab are also provided forsmall and large volume structures according to ASTM Standard E8.
