Wow, until you learn the difference between a Fuse Deposition Modeling (FDM) 3D printer and a "hot glue gun" no one wants you owning one anyway!
Consumers can buy any commercially available 3D printer out there, so define consumer 3D printer while you're at it. There are 3D printers that use liquid material to start with that are in the $5k-$100k range with a build volume of approx. 6in x 9in x 8in and up. There's the 3D Systems ProJet series [3dsystems.com] at the bottom end to mid range, and then there's the Objet series from Stratasys [stratasys.com] at the higher end.
Makerbots are a joke compared to the machines by Stratasys in particular. I worked supporting an FDM Dimension 1200es SST and a brand new Objet30. There were MakerBots and 3D Ssytem CubeX printers all over the place where I worked and they were either offline sitting on a desk somewhere because they never produced a good part, or they were producing crappy parts for students. You get what you pay for with 3D printers right now. That and most people don't understand that they low end printers fail for two primary reasons: 1. Bad environmental control of the room it's in (the air temp and humidty in the room *HAS* to be kept within the range specified for operation; putting these in large rooms with highly variable environmental conditions causes failure), and 2. They don't properly store their materials to prevent moisture uptake (the PLA and ABS materials will absorb moisture from the air and cause clogging; even worse is the support material as its uptake is typically higher and will completely encase your print head if you're not careful).
You have a lot to learn, it would seem, if you think 3D printers are nothig but glorified glue guns.

Producers purchase the methods of production all the time. All producers consume some input and produce some output for the general public, up to and including consuming the labor of consumers. Consumers are end product purchasers.
In market terminology, consumers represent the great majority of individual purchasers. This means middle-class, usually; everyone above middle-class can purchase middle-class goods, and there are relatively few poor people. Most goods extend down by having different grades which are targeted to lower-income consumers, expanding the market. When the market shrinks such that most consumers can't buy or aren't interested in a certain product (for example: a $3 million Ferrari or an extremely-specialized $50 vacuum tube), it's no longer a "Consumer good"; expensive consumer goods become "Luxury goods", and others become military or commercial goods.
A consumer-grade 3D printer would be a printer at a price point whereby it is useful to consumers. A producer making 500,000 copies of something he can sell will pay $50,000 for a 3D printer that can produce them for a total amortized cost of less than $10 each; a consumer needing one copy of a few trinkets may not pay $1,000 for a printer to produce 30 or 40 goods he could buy for a grand total of $200. If the great many available 3D templates appear which are useful to consumers and cheaper to fabricate than purchase, a 3D printer with low enough cost will appeal to consumers and become a consumer-grade good.
