Limitations

Castable 3D resin

Direct investment Casting  DC

Metal cast objects

Typical properties of Cast Metals

Cost effective direct investment casting of metal objects

Most castable competitor's 3D resins suffer from imperfections of fine detail finishes

Non Castable  3D resin

Indirect investment casting IC

Metal cast objects

Typical properties of Cast metals

 

Less cost effective indirect investment casting production of metal objects  with very high resolution Slower process since there are several time consuming production steps
Injection molding 3D resin Direct plastic, ceramic and metal feedstock injection in 3D printed durable injection molds Plastic, ceramic and metal objects Typical properties of Plastics, Ceramics and Metals Cost effective production of durable injection molds for simple shaped plastic, ceramic and metal injection Not suitable for complex intertwined shapes
Sacrificial 3D resin Direct plastic injection in 3D printed easy breaking & soft sacrificial molds Soft plastic, rubber or silicone objects Typical properties of soft Plastics, Rubbers and Silicones

Cost effective production of easy breaking & soft sacrificial molds* for complex shaped soft plastic, rubber and silicone injection molding

Not needed for simple 3d printed shapes, mold is lost during production
Sacrificial 3D resin Direct plastic injection in 3D printed sacrificial molds Plastic objects Typical properties of Plastics Cost effective production of sacrificial molds* for complex shaped plastic injection molding Not needed for simple 3d printed shapes, mold is lost during production

Sacrificial 3D resin

Direct CIM injection in 3D printed sacrificial molds

Ceramic objects

Typical properties of Ceramics

 

Cost effective production of sacrificial molds* for complex shaped Ceramic Injection Molding CIM, faster, more productive and without any maximum feature size limitation vs Direct 3D Printing or Production

 

Not needed for simple 3d printed shapes, mold is lost during production
Sacrificial 3D resin

Direct MIM injection in 3D printed sacrificial molds 

Metal objects

Typical properties of Metals

 

Cost effective production of sacrificial molds* for complex shaped Metal Injection Molding MIM, faster, more productive and without any maximum feature size limitation vs Direct 3D Printing or Production

Not needed for simple 3d printed shapes, mold is lost during production


* sacrificial molds are needed for making intricate complex shapes where the mold and the injected material are entangled
