A 3D printer company decided on new product features and design after extensive prototyping for its new printer. The company's marketing team created some buzz by posting a YouTube video displaying a variety of projects customers could create with the printer. The sales have been slow, and the company has sent multiple emails and prompts to coax people to purchase the new printer. Right now the cost to produce the printer is quite high, but the hope is that as sales increase those costs will decrease. What stage of the life cycle is the 3D printer in?
