DIY Chocolate Molds - Revisited Topic I think
Posted in: Geek Gear - Cool Tools
the standard nozzle from most printers will print PETG. The temps are lower than that of ABS, and the only restriction to printing ABS based on printer is a lack of heated bed.
Polycarbonate, in contrast, requires an upgraded hotend to allow for 300C+ temps. The e3d v6 all metal hotends are capable of this, and ship with a proper thermistor that will accurately read higher than 300C.
Most other non-upgraded hotends are limited to the thermistor's capabilities. A cheap i3 clone kit can easly do 260-270C.
Some kits to look at to get started with tinkering; Anet A8 and Prussa i3 Mk2. The A8 is a clone kit built in China, can usually find it around $170-$200 USD Sometimes cheaper. Prusa i3 is the original designer and uses higher quality parts and provides a warranty as well as support but sells for $699. The A8 can be upgraded bit by bit to be better, such as having an e3d v6 hotend.
If you're more adventurous, you can try and build a clone yourself. A video guide of doing just that is located here:
There's 6 parts to the series, and the build videos avg about 2-3 hours each.
