Hand plate project quotation needs to select the appropriate processing mode
according to the characteristics of parts to complete the hand plate faster and
better. At present, mainly engaged in handplant processing, CNC lathe
processing, 3D printing, film, fast mold, and so on. Today we are going to talk
about the difference between CNC lathe processing and 3D printing.
First, 3D printing is a material addition technology, CNC lathe processing is
a material reduction technology, so they are very different in materials.
1. Differences in materials
3d printing materials mainly include liquid resin (SLA), nylon powder (SLS),
metal powder (SLM), gypsum powder (full-color printing), sandstone powder
(full-color printing), wire (D FM), plate (LOM), and so on. Liquid resins, nylon
powder, and metal powder account for the vast majority of the industrial 3D
And CNC lathe processing materials are all a piece of plate, is the plate of
the material, by measuring the length and width of the parts + consumption, and
then to cut the corresponding size of the plate for processing. Numerical
control lathe processing materials than the selection of 3D printing, general
hardware, and plastic plates can be processed by numerical control lathe and
forming parts density than 3D printing.
2. Parts differences caused by the forming principle
As mentioned earlier, 3D printing is a kind of additive manufacturing. The
principle of 3D printing is to cut the model into N layers /N points and then
stack it up one layer at a time/bit by bit in order, just like building blocks.
Therefore, 3D printing can effectively process and produce parts with complex
structures, such as hollow parts, while CNC is difficult to achieve hollow parts
Numerical control is a reduction of material manufacturing, through the
high-speed operation of a variety of tools, according to the programming knife
cut out the required parts. Therefore, CNC lathe processing can only have a
certain radian rounded corner, and can not be directly processed out of the
Right Angle, through the line cutting/spark technology to achieve. The outer
right Angle CNC lathe processing is no problem, so the inner right Angle parts
can be considered to choose 3D printing processing production.
3. Differences in operating software
4. Differences in post-processing
There are few options for 3d printing parts after processing, generally
grinding, oil spraying, deburring, dyeing, and so on.
And CNC lathe parts processing options, in addition to grinding, oil
spraying, deburring, electroplating, screen printing, printing, metal oxidation,
radium carving, sandblasting, and so on.
The above is the difference between our CNC lathe processing and 3D
