I will take the question seriously, and consider reasons why Carbon 3D might choose to offer their technology through a yearly subscription, rather than building a product accessible to the consumer market. These reasons are speculation and do not reflect any specific knowledge about Carbon 3D, the details of their technology, or anything unique about their corporate mission.
1) The mission of a company, especially in the beginning while competition makes it possible, to make as much money as possible. If the technology is unique and brings good value to a large enough set of interested customers, it can easily consume the full attention of a company to service those customers. The price those companies pay for access may be higher than others would pay because their derived value is higher.
2) If a technology is new, and perhaps still somewhat immature, there may be very high support efforts and cost required. Through this time, the learning curve does it's job, the technology improves and matures, and the costs go down.
3) If the technology is immature, and perhaps is evolving quickly, it could be to the advantage of a supplier to only offer the technology on a service rather than capital acquisition basis. It simplifies replacing components.
4) If the technology is immature, selling the service may be easier than selling the hardware. It simplifies the acquisition process, and makes it easier for customer's to expand their usage since the supplier's capital is used to finance the machines instead of the customer's.
5) Even with a mature, proven technology, it can be advantageous to maintain a higher price point. The game is optimizing the profit on volume times price. The point they operate at is influenced by their perception of the market.
6) In the early adopter phase, it is critical that the customer experience be stellar. They may be limited in how rapidly they can scale in some critical dimension -- consumables supply chain, manufacturing capacity, trained installation technicians, local service offices, or many other limits. Anything going wrong makes for a bad customer experience.
It doesn't surprise me that they aren't going after the consumer market at this time.
But, I'm not in the CEO's office, and I don't see where his pain comes from. My purpose here is only to propose some plausible reasons why the company has not launched a consumer facing product.
