3d printers have revolutionized manufacturing today by being able to prototype and manufacture at an individual level.
I'm a partner with Fusion3, a US-based manufacturer of commercial-grade 3D printers)My understanding is that for most of its history, Makerbot built their 3D printers out of a factory in Brooklyn, NY. However, in 2016, they outsourced manufacturing to China (MakerBot will no longer make its own 3D printers
No, 3D pen filament is not typically compatible with 3D printers as they have different melting points and diameters.

There are Laser printers and Inkjet printers. There is also bubble jet, which is similar to inkjet.
the most common consumables used in consumer 3D printers using the FDM (fused deposition modeling) technology. A traditional inkjet printer needs ink cartridges in order to be able to print - the situation is similar for 3D printers, except that 3D desktop-type printers need plastic filament. These consumables are mostly available online in a variety of types of material (ABS, PLA, PVA, etc.), colors, diameters and lengths.
Ink jet printers are a very common alternative to laser printers. There are printers that use an LED instead of a laser. They work the same as a laser printer but are cheaper.
