Overview

What is 3D Printing?

3D printing builds parts layer by layer from digital models, enabling geometries that are difficult or impossible with subtractive methods.

SLA focuses on detail and smooth surfaces, SLS and MJF focus on functional nylon parts, and FDM focuses on fast and cost-effective large builds.

This family page helps you pick the process that fits your product stage: concept, functional test, pilot batch, or low-volume production.

3D Printing Processes

Each process is optimized for different material behavior, finish quality, and production economics.

SLA (Stereolithography)

Laser-cured resin printing for high detail and smooth surface quality.

  • Layer height down to 25 microns
  • Excellent visual quality and fine features
  • Clear and tough resin options
  • Best accuracy among polymer 3D processes

Visual prototypes, presentation models, transparent parts, and detail-rich geometry.

SLS (Selective Laser Sintering)

Powder-bed nylon process with no support structures and strong functional behavior.

  • Complex geometry with no support cleanup
  • PA12 and engineering nylon options
  • Strong mechanical performance
  • Good for nested batch builds

Functional prototypes, assemblies, and low-volume end-use parts.

MJF (Multi Jet Fusion)

Fast powder fusion process for repeatable production-quality nylon parts.

  • High throughput for batches
  • Consistent dimensional results
  • Smooth nylon surface relative to SLS
  • Strong economics at medium volume

Production batches, enclosures, fixtures, and repeatable functional components.

FDM (Fused Deposition Modeling)

Filament extrusion process for larger parts and cost-effective rapid iteration.

  • Large build envelope options
  • Broad material range: PLA, ABS, PETG, Nylon
  • Fast concept validation
  • Low cost for large non-cosmetic parts

Large prototypes, jigs, fixtures, and quick early-stage iterations.

DMLS (Metal 3D Printing)

Metal additive process for high-value functional components in advanced alloys.

  • Complex metal geometries
  • Titanium and stainless alloy support
  • Weight-optimized design opportunities
  • Best suited for high-value parts

Aerospace, medical, and high-performance metal components.

How to Choose the Right 3D Process

Use this as a quick process picker before opening detailed process pages.

SLA

Visual quality and fine detail

Advantages

  • Best surface quality
  • High resolution
  • Transparent options

Limits

  • Lower toughness on standard resin
  • Support cleanup required

Low to medium for small-medium parts

When appearance and detail are higher priority than impact resistance.

SLS/MJF

Functional nylon parts and production batches

Advantages

  • Good strength
  • Complex geometry
  • Good batch economics

Limits

  • Rougher finish than SLA
  • Post-finish often needed for cosmetics

Medium, with good scaling at volume

When function and repeatability are primary requirements.

FDM

Large and low-cost prototypes

Advantages

  • Fast setup
  • Large part capability
  • Low cost

Limits

  • Visible layer lines
  • Lower precision than SLA

Low for concept and larger geometry

When speed and budget are primary constraints.

Quality and Delivery

Engineering Review

Each model is checked for manufacturability before production.

Inspection

Critical dimensions are checked based on process and customer tolerance needs.

Lead Times

Typical lead times range from 2 to 7 days, plus optional finishing.

Frequently Asked Questions

Answers for 3d printing process selection and execution.

Which process should I start with?

Use SLA for visual prototypes, SLS/MJF for functional nylon parts, and FDM for large cost-sensitive prototypes.

Can I compare multiple processes on one part?

Yes. Upload once and compare process options in the same quoting workflow.
