You don’t need to know every acronym to start. Use these broad introductions to ask a provider better questions.
FDM / FFF
Practical parts, layer by layer
A nozzle deposits melted filament in layers. Commonly considered for early prototypes, enclosures, fixtures, and small batches. Ask about layer direction, surface finish, and dimensional tolerances.
SLA, MSLA, and DLP cure resin with light. Often considered for models, detailed miniatures, and presentation pieces. Ask about resin properties, post-curing, brittleness, and intended use.
Common materials: provider-specified photopolymer resinsExplore providers SLS / MJF
More freedom for functional forms
Powder-based processes often support complex nylon geometries without the same support structures used in filament printing. Ask about wall thickness, surface finish, and batch economics.
Common material: Nylon; confirm exact gradeExplore providers Before you print
A useful first conversation
Describe your intended use, quantity, dimensions, finish, and deadline. Ask about design checks and material suitability. Share confidential files only after agreeing directly with your provider.
These are general process introductions, not engineering specifications. Confirm material properties and suitability for your application with the provider. Directory listings do not establish suitability for medical, aviation, or other safety-critical use.
