SLA and CNC Which Is Cheaper？
CNC model production cost：
CNC processing consumables use actual materials such as PP directly, and the material cost is low.
The CNC process needs to be programmed and split.
Due to the complexity of parts and material consumption, the more complex the parts, the greater the workload of splitting and programming. The more complex the post-processing splicing process is, the more labor time is needed, and the higher the cost is.
The cost of SLA model is:
SLA equipment can basically achieve "unattended", a person can operate 3-5 SLA devices at the same time, and the labor cost is low, but the material of SLA is a specific photosensitive resin, and the procurement cost is high.
So in terms of cost, because the cost of SLA process is mainly related to the weight of parts, the cost of SLA is better than that of CNC for high fineness, thin-walled or hollow structure parts, while for the relatively simple structure of heavy components, the cost of CNC is dominant.
The cost of making SLA has nothing to do with the complexity of the parts, but mainly depends on the weight of the parts and the depreciation of the equipment itself.
