The Differences Between CNC Machining & SLA

2016-11-18

Process: 

CNC Machining is a subtract manufacturing process,which means the raw material will be removed with a variety of precision cutting tools .

CNC machining


SLA (stereo-lithography) is a "rapid prototyping" process which will create an object.

 

SLA

Materials:


CNC:


Plastic: PMMA (Lucite Acrylic), PC, ABS,PP, POM (Delrin), HDPE,PTFE (Teflon), Ultem, Nylon,etc

Metals: Aluminum, Copper-based materials, Tool steel,Stainless steel,etc


 

SLA: Resin(white or Transparent),ABS

 

Leading time

Compared with SLA , CNC Machining will need more time to machine.Generally speaking,SLA will need 1 -2days and CNC Machining will spend 3-4days!

 

Surface finish

CNC Machining & 3D Printing could have a lot of surface finish like polish,sandblast,chrome plating,painting,silk-screen etc. The effects will be similar.
