Die-casting vs. Sand Casting vs. SLM

Die casting, sand casting and Selective Laser Melting (SLM) are among the most important manufacturing processes for producing metal components. Each process offers specific advantages in terms of geometry, production volume, material selection and application area. The following overview highlights the typical applications and characteristics of each manufacturing method in direct comparison.
Requirement Die Casting Sand Casting SLM
Typical Application High production volumes with consistent part properties Large components and high material cross-sections Complex geometries, functional integration and lightweight design
Suitable For Medium to high-volume production Low to high-volume production Single parts and small production runs
Initial Costs Very high due to tooling costs Medium to high due to pattern and mold costs Low, as no tooling is required
Design Freedom High design flexibility Very flexible Maximum design freedom
Complex Internal Structures Limited Highly limited Ideally suited
Dimensional Accuracy High Medium to high Very high
Surface Quality Very high Medium to good Good, post-processing possible
Part Size Small to medium Small to very large Small to medium
