Common structural materials PET,PC add ABS-plastic rapid prototyping 
PET, known in Chinese as polyethylene terephthalate or PET, is one of the most common transparent plastics.
1.The advantage of PET
1)Good dimensional stability.
2)Excellent mechanical properties.
3)High transparency, good light transmittance, light transmittance up to 86%.
4)Good weather resistance.
5)Resistant to organic flux, oil and weak acid.
6)Good water resistance.
7)With self - extinguishing.

2.The disadvantage of PET
1)Mechanical properties of directional, high mobility.
2)The crystallization rate is slower.
3)Drying and processing conditions are strict.
4)Material shrinkage rate is high.

3.The density of
The density was 1.37 g/cm3

4.PET surface treatment
Vacuum plating, spraying, screen printing, pad printing, etc.

5.The connection method
The connection mode is divided into buckle, screw, hot-melt, ultrasonic, double-sided adhesive tape, etc.
6.Scope of application
It is often used for lenses, bearings, chains, tapes, etc. It can also be blown into hollow soft drink bottles.

PC+ABS is one of the commonly used combination plastics, composed of PC70 % +ABS30 %, with slight difference in each brand.

1.The advantages of PC + ABS
1)Set PC, ABS function, with the comprehensive characteristics of the two.Such as ABS machining characteristics and PC excellent mechanical characteristics, thermal stability.
2)Increase the stability of ABS in heat resisting dimension.
3)Improve PC low temperature.

2.Shortcomings of the PC + ABS
1)It's more expensive than ABS, but cheaper than PC.
2)The strength of the material is worse than PC, but better than ABS.
3)Liquidity is worse than ABS.

3.The density of
The density was 1.18 g/cm3.
 
  1. PC+ABS surface treatment
Vacuum plating, spraying, screen printing, pad printing, etc.
5.The connection method
The connection mode is divided into buckle, screw, hot-melt, ultrasonic, double-sided adhesive tape, etc
6.Scope of application
It is commonly used in the case of mobile phones, digital products, electronic products and computer equipment.
