Additive Manufacturing & 3D Printing
.Ist das alles die gleiche seite?
Additive manufacturing builds parts layer by layer from powder, filament, or resin instead of removing material. The suppliers below build printing systems, supply powders and feedstock, or print parts to order for prototyping and series production.
What additive manufacturing suppliers provide
Suppliers in this category cover both the machines and the parts. On the equipment side the scope includes powder-bed fusion systems for metals and polymers, material extrusion and vat photopolymerisation machines, binder jetting, and the peripheral equipment for powder handling, depowdering, and heat treatment. On the service side it includes printing to customer drawings, from single prototypes through to qualified series parts, often combined with post-processing, machining, and inspection. Materials range from metal powders and technical polymers to photopolymer resins. Core competence lies in translating a part geometry into a build job that holds tolerance and density repeatably. In the pre-selection phase, compare which processes and materials a supplier actually runs, the build volumes available, and whether they document part qualification.
Relevant standards
Terminology and process categories are defined in ISO/ASTM 52900. Qualification of operators and process qualification are covered by ISO/ASTM 52926 and ISO/ASTM 52920, and additive manufacturing quality management requirements by ISO/ASTM 52920 in combination with ISO 9001. Aerospace supply typically adds EN 9100.
Frequently asked questions
Should I look for a machine supplier or a printing service?
Both are listed here. A machine supplier sells you the system to run yourself; a printing service produces the parts for you. Check which model a supplier offers before shortlisting.
