I would post a zero star review if it was possible. I was an early adopter of Markforged and paid over $6000 to purchase a Mark One just 4 years ago. Now, Markforged is completely discontinuing all support, parts, materials (nylon), and service on these Mark One printers. In 6 months I will be left with a $6000 paper weight and Markforged doesn't seem to care. They tell me I can upgrade but I'll have to shoulder the cost at an additional $3500. The company does not stand behind their product or the customers that helped them become what they are today. I would not recommend.
