3D Plastic Printers

There are two flavors of plastics printing.

Type 1 is called “Filament” printers.  

These use 2.2 pound (or smaller) rolls of meltable plastic filaments.  Which plastic?  Well, there’s a long discussion that will have its own page one of these days.

One type is PLA – which is not hard to work with, but is soft and not food-safe.  Then there is ABS (and other  styrenes) which are stronger, but you may wish to install positive ventilation because of chemic al smells.  There are also food-safe plastics in case the Dollar Store is too far and you just gotta print up some plastic dinnerware…

Example to look at on Amazon: Comgrow Creality Ender 3 3D Printer Aluminum DIY with Resume Print 220x220x250mm.

Type 2:  These are called “Resin” printers.

They use a thin stream of UV-curing plastics (like what your dentist may use).

These will generally have a smaller build area, should be vented, and produce (depending on resin) harder plastics.  Which means they also cost more.

Example on Amazon to look at: ELEGOO Mars UV Photocuring LCD 3D Printer with 3.5” Smart Touch Color Screen Off-line Print 4.53in(L) x 2.56in(W) x 5.9in(H) Printing Size Black Version.
