Large 3D printers

3D Printing (Additive Manufacturing) is a Family of Technologies

When we talk about 3D printing, it is a catch-all phrase that encompasses several distinct technologies, each with its own strengths.  Here are some comparisons of additive manufacturing options in plastic, metal and composites:

3D Printed Plastics

Fused Deposition Modeling (FDM)

Learn more about FDM

Standard Materials: ABS

Relative Cost: ★★☆☆☆

Machine Finish: ☆☆

ABS Prime Finish

Typical Lead Time:  2-5 Business Days

Specialty Materials: PC, nylon, ULTEM and many more (See FDM page)

Relative Cost: ★★★★☆

Machine Finish: ☆☆

Typical Lead Time: 3-7 Business Days

FDM Pros: Very high accuracy on large parts, diverse materials, rigid and tough, fast turnaround, sparse fill for light weight with high part volumes

FDM Cons: Striated machine finish, low resolution on features under 0.030"

Polyjet (Objet) Printing

Learn more about Polyjet

Standard Materials: Acrylic and polypropylene-like

Relative Cost: ★★★☆☆

Machine Finish: 

Typical Lead Time:  2-5 Business Days

Specialty Materials: ABS-like, various elastomers and digital materials (See Polyjet Page)

Relative Cost: ★★★★☆

Machine Finish: 

Typical Lead Time: 3-7 Business Days

Polyjet Pros: Top quality detail, best surface finish, clear material option, embedded textures, fine features, single piece mechanical assemblies

Polyjet Cons: Resins - not industrial thermoplastics, lower heat resistance, better for smaller parts

Selective Laser SIntering (SLS)

Learn more about SLS

Standard Materials: Nylon and glass filled nylon

Relative Cost*: ★★★☆☆

Machine Finish: ★★★☆☆

Typical Lead Time:  5-10 Business Days

Specialty Materials: Rubber (TPU), carbon filled nylon and other composites (See SLS page)

Relative Cost: ★★★★☆

Machine Finish: ★★★☆☆

Typical Lead Time: 5-10 Business Days

SLS Pros: Real thermoplastic and thermoplastic composites, uniform matte finish, great thermal and mechanical properties

SLS Cons: Large and thick parts can warp, longer production lead times, porous material, low resolution on features under 0.030"

*In volume SLS can become one of the least expensive printing processes.

Large Format 3D Printing

Learn More about Large Format 3D Printing

Standard Materials: Epoxy infused Acrylic

Relative Cost*: ★★★☆☆

Machine Finish: ★★★☆☆

Typical Lead Time:  5-10 Business Days

Specialty Materials: Sand (Sand Casting), Low Ash Burnout Resin (Investment Casting)

Relative Cost: ★★★☆☆

Machine Finish: ★★★☆☆

Typical Lead Time: 5-10 Business Days

Large Format Pros: Largest build size of any 3D printers, cost effective for large parts, casting patterns and molds without any additional tooling

Large Format Cons: Not as durable as SLS or FDM, not intended for small objects, longer production lead times compared to smaller printers

3D Printed Metals

Note: 3D printed metals tend to be 5 to 10 times the cost of 3D printed plastics and are often more expensive than machined metals.

Direct Metal Laser Sintering (DMLS)

Learn more about DMLS

Standard Materials: Aluminum, stainless steel, tool steel and titanium

Relative Cost: 

Machine Finish: ★★☆☆

Typical Lead Time:  5-15 Business Days

Specialty Materials: Cobalt chrome, inconel, (nickel alloy) and more (See DMLS page)

Relative Cost: 

Machine Finish: ★★★☆☆

Typical Lead Time: 5-15 Business Days

DMLS Pros: Stronger than cast parts, works with exotic and expensive to machine metals, can make parts that are otherwise not manufacturable

DMLS Cons: Limited part size (generally under 10"), rough finish, lower tolerance than machining, generally more expensive than machining

Printed Metal

Learn more about Printed Metal

Standard Materials: Stainless steel bronze alloy

Relative Cost: 

Machine Finish: ★★☆☆

Typical Lead Time:  10-20 Business Days

Specialty Materials: None

Relative Cost: N/A

Machine Finish: N/A

Typical Lead Time: N/A

Printed Metal Pros: Half to a third the cost of typical DMLS parts, beautiful bronze polish look, easily plated, larger bed than DMLS

Printed Metal Cons: Single available material, low strength to weight ratio for metal, long lead time relative to other 3D technologies

3D Printed Composites

Colorjet Full Color Composite

Learn more about Colorjet

Standard Materials: Full color composite

Relative Cost: ☆☆

Machine Finish: ★★☆☆

Typical Lead Time:  2-5 Business Days

Specialty Materials: None

Relative Cost: N/A

Machine Finish: N/A

Typical Lead Time: N/A

Full Color Composite Pros: Full gradient of 390,000 colors, generally least expensive material, fastest way to make large models, very rigid

Full Color Composite Cons: Features thinner than 0.100" can be brittle, does not have the flex of real plastic
