Pros | Cons | |
FDM | ~Low cost ~No pollution ~Simple and clean working enviroment | ~Low precision up to 0.3mm ~The surface of the item is rough ~ Need the foundation to build up the upper layer |
SLA | ~Smooth finishing surface ~High precision up to 0.15-0.2mm ~Can be use for very complex shapes and designs | ~Resin is fragile and likely to absorb moisture from environment, cast it self to bend. ~Must use light sensitive resin as the material therefore the cost of the it is comparable higher. |
SLS | ~ The hardness of the material is high ~ Only for plastic meterials also an be use in varity of material such as ceramic, metal,wax, ect. ~High precision up to 0.2mm. Can be use for functional testment. | ~Time consumming.Need 2 hour for heating up the powder and 5-10 hours to cool the finish object. ~The surface of the object is rough as it is made by power and very difficult to refine it . |
