TechnologyHow it worksBest forProsConsTypical price
FDM / FFFAn FDM/FFF printer feeds a spool of thermoplastic filament into a heated nozzle (the hotend), which melts it and deposits it onto a build plate one layer at a time. The toolhead moves in X and Y while the bed (or the gantry) indexes down in Z after each layer. Most consumer machines print PLA, PETG, ABS and TPU at roughly 180–260 °C nozzle temperatures onto a heated bed. Multi-material systems swap or mix filaments to print in several colors at once.Beginners, Functional parts, Large prints, Multicolor, Print farms & small business
  • Wide material selection
  • Least expensive entry point
  • No toxic chemicals or wash steps
  • Largest community and support base
  • Prints are tough and functional
  • Visible layer lines
  • Slower than resin for fine detail
  • Warping on some materials without an enclosure
  • Dimensional accuracy depends on calibration
$150–$4,000 (consumer); up to $10,000+ for prosumer CoreXY
Resin (SLA, MSLA, DLP)Resin printing cures a photopolymer liquid with light. SLA uses a galvo-steered laser to trace each layer; MSLA uses an LCD mask over a UV LED array to cure an entire layer at once; DLP uses a projector. The build plate lifts out of a vat of resin, so the part grows upside-down. After printing, parts must be washed in solvent (usually IPA) and post-cured under UV to reach full strength.Miniatures & fine detail, Jewelry & dental, Engineering materials, Education
  • Extremely fine detail and smooth surfaces
  • Isotropic mechanical properties
  • Great for miniatures, jewelry and dental
  • Tight tolerances
  • Toxic, messy resin handling
  • Wash and post-cure required
  • Smaller build volumes than FDM
  • Resin is more expensive per liter
  • Limited flexible materials
$150–$600 (consumer MSLA); $1,500–$10,000+ (professional SLA)
SLS (powder)An SLS machine spreads a thin layer of polymer powder (usually PA12 or PA11) across a build bed, then a CO₂ laser selectively sinters the cross-section of the part. The bed lowers, a fresh layer of powder is recoated, and the process repeats. Unused powder supports the part, so no separate support structures are needed. Finished parts are dug from a cake of unsintered powder and bead-blasted clean.Engineering materials, Print farms & small business, Functional prototypes
  • No support material
  • Strong, functional nylon parts
  • Complex geometries and living hinges
  • Good mechanical properties
  • Expensive machines and powder
  • Powder handling and safety concerns
  • Grainy surface finish
  • Limited consumer options
$5,000–$30,000 (benchtop SLS); $100,000+ (industrial)
MetalMetal 3D printing spans several processes. SLM/DMLS uses a high-power laser to fully melt metal powder in an inert chamber. Bound-metal FFF extrudes a filament loaded with metal powder and binder, then the green part is debound and sintered in a furnace. Binder jetting deposits a binder into a metal powder bed, then the part is sintered. All routes require post-processing (support removal, heat treatment, machining) to reach final properties.Engineering materials, Jewelry & dental, Print farms & small business
  • Dense, functional metal parts
  • Alloys like stainless, titanium, Inconel
  • Complex internal channels possible
  • Strong as-cast or sintered properties
  • Very expensive machines and material
  • Inert gas and safety requirements
  • Significant post-processing needed
  • Steep learning curve
$5,000–$20,000 (bound-metal FFF); $80,000–$500,000+ (SLM)
