Metal 3D printing service overview
Multiple components of complicated shape can be manufactured at one time.
It has the following effects.
- · Process reduction by one molding process
- · Weight reduction by providing cavities in parts
- · Utilized as a cooling water pipe, etc.
We also carry out secondary processing (finishing processing).
We will polish the surface and inner surface of the product with high precision.
※ Inconel 718 was added to the material. (Introduced from 2018/6)
Principle of metal 3D printer
The metal 3D printer we adopt is "powder head (SLM) method.
We will detail below.
- Thinly lay metal powder
- Laser is irradiated to the position where you want to make a shape, When the powder in the irradiation area melts and solidifies when it cools down
- Manufacture the desired shapes 1 and 2 repeatedly
- Take out the finished product
- Separate the base plate that is integrated with the finished product
- Remove support
merit
In our metal 3D printer contract manufacturing service, we provide accurate secondary processing with a consistent one-stop service in addition to shaping, base plate separation and support removal.
The weakness of metal 3D printing is surface roughness.
This surface roughness can be solved with our precision micro processing technology.
We will process to the finishing requested by the customer.
Since we respond collectively from modeling to finishing, we can design with consideration for secondary processing.
Finishing example(closed impeller)
Before polish
(surface roughness ：Ra20μm)
After polish
(surface roughness ：Ra0.5μm)
