Metal 3D printing


Metal 3D printing

What is metal 3D printing?

Metal 3D printing is a process of manufacturing three-dimensional parts based on digital files. It usually uses layer-by-layer processing or solidification of thin metal powder materials to make complete parts. This technology can produce complex parts that cannot be achieved by traditional techniques such as die casting, forging and CNC machining.

The advantage of metal 3D printing;

3D printing has many advantage, especially if you know how to optimize product designs to take advantage of them. Advantage include:

Metal 3D printed parts are completely dense, containing complex geometric shapes and precise internal features that cannot be manufactured using traditional machining alone.

The design can be done quickly with minimal material waste while maximizing strength.

Conformal cooling channels greatly improve performance and resistance to thermal stress, making it ideal for aerospace and automotive applications
Multiple identical parts can be make on one machine at the same time, which greatly improves production efficiency.

Metal 3D printing process:

First, a 3D CAD file must be provided for the design. In order to get the best results, our engineers must check your CAD drawing files in advance and optimize the design if necessary. This can include optimizing the build direction and adding support structures to areas where gravity may cause the features to distort during printing. These support will be removed later

We then used specialized software to cut the drawing into multiple cross-sectional layers, with each layer representing a 20-60μm thickness of the final shape.Finally, we upload the slice file to the machine to be printed.Using the Renishaw AM250, an advanced metal 3D printer for rapid prototyping and manufacturing.

Metal 3D printing tolerances:

The general tolerance for metal 3D printing is +/- 0.5mm. However, it depends significantly on the geometry of the part being printed. See more guidelines to follow when designing metal 3D printing.

Metal 3D printing materials:

Currently, we provide 3D metal printing of titanium, stainless steel, maraging steel and aluminum. Each material has unique advantages related to mechanical properties, weight, corrosion resistance, etc. Economic costs also need to be considered, so our engineers are happy to advise you on the best materials for your application and budget.

CNC Machining Prototyping

The Difference Between CNC Milling And CNC Turning Process

The Difference Between CNC Milling And CNC Turning Porcess

1.Working principles is different.
The working principles of CNC turning machine is that the parts is rotating,and the tooling is moving when machining. On the contrary,the tooling of CNC milling machine is rotating,the parts is moving when maching.

2.Programming is different.
We need to put the data of XYZ for CNC milling machine,but for CNC turning machine,we just need to put the data of XY.

3.The machining range of parts is different.
CNC turning machine can machining axis,groove,end face and thread.CNC milling machine can machining flat face,groove,hook face of parts,etc.

4.The structure of machine is different.

5.The operating method is different.

6.The mian spindle speed of CNC turning machine is not very high,but the spindle speed of CNC milling machined is very high.

What are the advantages of SLS 3d printing process?

Compared with other rapid prototyping processes,the SLS 3d printing process for prototype production is unique in that it can directly produce metal prototypes.At the same time,this process also has the following advantages:

  1. The SLS 3d printing process is relatively simple,depending on the type and particle size of the material used,and the geometry and complexity of the prototype.The process can generally achieve a tolerance of ±0.15mm within the entire range of the prototype.When the powder particle size is less than 0.1mm,the accuracy of the prototype after molding can reach ±1%.
  2. There is no need to design a support structure,and the suspended layer that appears during the lamination process can be directly supported by the unsintered powder; and the material utilization rate is high,because there is no need to make a base support,the material utilization rate is high; the production cycle is short,and the application surface wide.

The Importance Of Painting Prototype

The Importance Of Painting Prototype
Painting process is one of the surface treatment that be widely use for products.Below is some advantage of the painting for product.
1.Painting can cover the slight flaw on the surface of product;
2.Product can obtain a variety of surfaces by painting,such as color and gloss.
3.Increasing the surface hardness and the conflict of resistance of parts.

In a word,painting can beautify the appearance of product and protect the product structure from damage.For example,the appearance of the CNC machined prototype after painting is very closed with the finished product.But there are some plastic is without stronger color adhesion and is hard to painting color,such as POM and PP.

Die casting-Aluminum part

Aiming at the shortcomings of die-cast aluminum: “Due to the high speed of liquid metal filling the cavity when die-casting aluminum, the fluid state is unstable, so the general die-casting aluminum method is used, and the casting is prone to pores and cannot be heat treated.” So it is easy to cause poor appearance of the product,and the defective rate of the product is very high.

Now there is a new process: extrusion aluminum + die-cast aluminum. That is, the exterior surface of the middle frame of the product is extruded with profile, and the internal structural surface of the middle frame is die-cast. The process is to place the aluminum profile into a mold after preliminary CNC processing, and then die-cast the internal structure. At high temperatures, the contact surface between the profile aluminum and the die-cast aluminum is partially molten, which makes the two more closely integrated.


  • Significantly reduce CNC machining time, improve efficiency and reduce costs.
  • Close structure
  • The appearance surface anodizing not affected by die-cast aluminum, avoiding the defects of die-cast aluminum anodizing.

The E-make team has more than 30 years of combined experience in prototype machining, CNC manufacturing(metal,plastic parts machining), vacuum casting service and 3D printing service.

What Is The Difference Between Anodizing And Painting

What Is The Difference Between Anodizing And Painting

Painting can be used in plastic made parts and metal made parts,but anodizing only can be used in aluminum alloy made parts.

2.The persistance of color.
Painting is making the parts coated with a layer paint,which might will come off with the time goes on.Anodizing is making the color permeate into the inner of prototype and there will have oxidation film be formed on the surface of the prototype,which are not easy to fade.

3.The effective of surface are different.
The color by anodizing has metal texture and looks with high quality.

What are the classifications of toy prototypes?

According to the materials used, the processing of toy prototypes can be divided into: plastic silicone and metal materials.

And According to the product effect to be achieved by level, it can be divided into: appearance, structure and main function prototype.

  1. Appearance prototype: Mainly inspect the appearance of the design, which requires high requirements for appearance surface finish and accurate color, so the internal treatment requirements are not high.
  2. Structure Prototype: It mainly detects the rationality of the structure of the product. The requirements for the size of the product are relatively high, and the requirements for the appearance are relatively low.
  3. Functional prototype: It is required to achieve the same appearance, structure and function as the real product, which can be understood as a finished product that is not on the market, so it is a type of prototype with high requirements and difficulty.
