3d printing out of the hand plate is relatively rough, low precision; and CNC processing out of the hand plate high precision, generally can reach plus or minus ten silk, the choice of high-speed drilling and tapping center processing out of the metal hand plate, in the precision can arrive.
2, the cost is different
3D printing processing programming than CNC programming is simple and easy to learn, and according to the gram charge, so the lighter weight of the hand plate can be used to 3D printing processing, large volume and weight of the hand plate advocate the use of CNC processing will be more affordable.
And CNC processing of the material is relatively wide, simply can process all the plastic and metal (such as stainless steel, aluminum, etc.), and its stroke is relatively large, at least 1 meter or more, like the gantry machine, processing planning can even be the whole processing two to three meters of planning. Because the material used in 3d printing is liquid, so the characteristics of 3d printing hand board than CNC processing out of the hand board. In the strength, 3d printing molding hand board strength is poor, in the above a screw are briefly cracked; in high temperature, CNC processing out of the pc hand board in 90 degrees of high temperature will not be deformed, and 3d printing in the case of 60 degrees will be deformed. CNC hand board is directly processed in the plate above, so all aspects of the characteristics are better. The difference between the two is still very big.
