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.

Precision:

0.2mm

Application:

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

Note:

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

The Problem That Metal 3D Printing Have

/in , /by

The Problem That Metal 3D Printing Have
1.Surface Finish.
The surface of the metal parts that make by 3D printing is very rough.
2.Pore.
The inner of 3D printed metal parts will have small pore if the metal powder is not fully melted.These samll pore will reduce the density of parts and cause the crack and the fatigue problem.So that the choice of the metal powder is very important.
3.Density.
The density of the metal parts are inversely correlated with the quantity of small pore.Besides the quantity of small pore, the parts density also can be effect by the grain size of powder. Globular grain not only can improve the fluidity of powder,but also can improve the density of parts.
4.Residual Stress
The residual stress is cause by the heat and cold change, expansion and contraction during the 3D printing process.When the tensile strength of residual stress over than the material’s,the parts will have defect,such as crack.
5.Others

What Material Can be Use For 3D Printing?

/in , /by

3D printing is a technology that we usually use in making prototyping.According to the different requirement of prototype,that different material with different specification is need.There is some material as below that can be use in 3D printing.

1.Polymer Material
With good strength,impact resistance and heat resistance,polimer material is a most widely used of 3D printing materials,which usually be use to make industrial parts.The common polymer material we use is ABS,PA,PC,PEEK,etc.

2.Metal Material
The form of metal material for 3D printing is metal powders,metal foil and metal wire.We can print these metal material by SLS,DMLS and EMB 3D pritning machine.

3.Ceramic Material.
Ceramic material with high strength,high hardness,low density and chemical resistance,is usually be use as aviation,car and home decoration material.

4.Composite Material
Carbon fiber is a emerging 3D printing material,with nice high temperature resistance and corrosion resistance
