A new THK high precision linear stage is already $800 USD if purchased directly from THK. A non-modified new DLP projector will cost you at least $550 USD. The printer uses all-metal body (2mm thick brushed aluminum) ensuring reliability. There were countless hours that went in to developing and testing all parts for the printer. This is not including the hours we spend for individual technical support for customers who need it.
There are no laser type SLA printer that uses industrial grade linear stage. And the laser galvo is much cheaper than the DLP projector. Of course the performance between the laser and DLP printer is different. Resolution, reliability, and speed of a DLP printer is much better than laser printers.
To come up with an integrated software (including supports generation, slicing, hollowing, and printer control) will increase the cost of the printer substantially. Allowing customers to use 3rd party software not only lowers the price of the printer but also allows them the flexibility to change the code. This software chain has been used by all of our customers and resulted in great prints.
If you have any questions about using the software to create your prints, please feel free to contact us. We will be more than happy to help you out!
