- improve resolution (atomic)
- higher temperatures
- lower temperatures
- reduce parts of the printer
- freeze the extruder
- heat all the filament at once and pour it into the extruder
- make it easier to use (McDonald's screen)
- touch screen Arduino
- design the print using a touch screen and a pen
- make it easier to maintain (none, unbreakable, self healing)
- filament would be less brittle because it would stay melted in a block, so it would be harder to break
- reduce waste (zero)
- make the printer out of reclaimed wood
- make the printer out of recycled electronics
- use less energy (zero or ambient)
- solar power
- hydro power
- quieter printing (soundless)
- include sound proof headphones with the printer so the person printing does not have to hear anything
- make a door to the front of the printer that has soundproof technology so closing the door would create a sound proof seal, and a camera can be filming it from inside to see the print
- ubiquitous printing (everywhere)
- create a teleportation device that sends prints to anywhere
- print smaller (nanoscale)
- shrink the printer using a shrink ray that will exist soon
- print bigger (apartment complex, Great Wall of China, planet?)
- the pouring of the filament makes the melted filament form to the size of the big extruder, so it could be as big as we want
- enable real-time feedback
- install a camera on the printer that can connect to the internet and creates a livestream so people can give feedback as it prints
- make it safer (infant approved)
- put a child lock on the printer
- create a infant-based learning system for babies to learn about 3D printing so they won't hurt themselves
- make is smell good (designer imposters?)
- add an air freshener to the printer that makes the spinning of motors smell good
- add fragrance to filament so when it melts, it smells good
- make it from current waste products (CO2, flyash, spent fuel rods?)
- burning trash to produce fuel that powers a battery
- enable ongoing printing without people
- use a figure of a boxer with a huge punching glove to punch print off once print finishes
- ejecting print bed that propels the print off of the bed
- use a "claw game" type claw to pick up the print when the print finishes
- two boots that kick the print until it flies off
