The Advanatge And Disadvantage Of SLS 3D Printing

The Advanatge And Disadvantage Of SLS 3D Printing


1.Most materials can be used for SLS 3D printing,such as ceramic powder,nylon powder,etc.

2.The precision of parts by SLS printing is about ±0.2mm.

3.SLS printing do not require the structural support when working.

4.The material for SLS printing have high utilization,and the price is cheaper than the material for SLA printing.



1.The surface of parts by SLS printing are rough.If you need the parts with smooth surface,SLA printing will be better.

2.There will have bad smell when printing.

3.The machining time is longer than SLA much because SLS printing need the preheating time and the cooling time.

3D printing PLA material

3D printing PLA material


PLA (Poly Lactice Acid) is a new type of biodegradable material. It can be processed from starch raw materials , and the production process is pollution-free and can be degraded.

Material advantages:

Directly degradable environmentally friendly bioplastics, low melting point, small shrinkage ratio, not easy to warp or deform, good printing flatness, suitable for models that do not require processing.

Material weaknesses:

Temperatures above 60°C will deform PLA materials. PLA material is fragile and cannot be used to make handles for tools or parts that will drop repeatedly.




Auto electronic lamps and other parts production.

Can be used for lens packaging fluid analysis RTV mold durable concept model wind test and other practical production activities


PLA can break if it is slightly bent and is not suitable for making thin things.

The difference between anodizing and painting in the surface finish of prototype processing

Anodizing and painting are common surface finish processes when making prototype models. Although anodizing and painting both make the surface of the prototype color, there are still differences between them, which are mainly reflected in the following three aspects:
1.For different materials, painting can be applied to many materials for prototypes, such as metal, plastic and resin, and anodizing is a surface finish process that only aluminum alloy prototypes have.
2.The color persistence is different. Because the painting only painting a layer of paint on the surface of the prototype, it will fall off over time, and the anodizing is to soak the aluminum alloy prototype in the potion to form an oxide film on the surface.Because the alumina produced by anodizing is a stable substance, it is difficult to react with oxidation in the air, so the color of the surface is relatively stable and not easy to fall off.
3.The effect is different. The anodizing color has a metallic texture. If you use painting, you will not be able to adjust that effect anyway.

Custom Rapid Prototyping

Rapid Prototyping

In order to verify the appearance,structure and dimensions of new product,to see if the new product’s design is perfect or not,rapid prototyping is the first step.Because we can recognize the design problem when we test the prototype.In other words,rapid prototyping can help to reduce the risk of developing mould.
According to the material used for making prototype,there are plastic prototype,metal prototype and rubber prototype.
Plastic prototype is making out of plastic material,such as television,displayer,etc.
Rubber prototype is making out of rubber material,mainly be use for displaying the appearance of product,such as car,phone,toy,etc.
Metal prototype is making out of aluminum alloy,stainless steel,etc.It is mainly be used for making high-grade product,such as laptop.
According the effect of the prototypes,there are exterior prototype,structural prototype and functional prototype.
Exterior prototypes are solid and without functionality,which made for checking the appearance of the product.
Structure prototypes are hollow,which made for checking the the rationality of the product structure.It will be functional if install electronic components into the structure prototype.
Functional prototypes need to has same appearance,structure and functionality as the finished product.That is why machining functional prototypes is harder than the exterior prototype and structural prototype.
Both of SLA/SLA 3D printing and CNC machining process can be used for making rapid prototyping.Shenzhen E-Make Model Technology Co., Ltd are specialized in rapid prototyping,is welcome to contact us for custom your design!
