A: This printer has a major design flaw. It can't use any material successfully, unless you are willing to figure out a way to un-jam the filament, which invariably happens. You will waste many hours trying to un-jam the filament. The design is poor. It doesn't isolate the hot end from the filament drive, so the plastic is too soft at the drive mechanism and the drive just cuts into the filament instead of moving it when warm.
A: For now, the Replicator Desktop (5th Generation) is recommended for use with PLA. Coming in late 2015, you'll be able to print in limestone, maple, bronze and iron PLA Composite Filament. Be sure to stay tuned!
A: Unfortunately it can only do PLA at this time. ABS requires a heated bed which this machine doesn't have. Previous makerbots could do both. Makerbot is supposedly testing more types of filament, but no word on when any of it will be available.
A: The MakerBot 5th Generation printer can use a few different materials from MakerBot. Here is a summary of each of them! 1.PLA Composite: This isn't out yet. It will arrive some time late 2015. It is a mix of PLA and other materials such as Limestone, Iron, Bronze, Maple.etc This gives the pros of PLA and the benefits of the materials. Very cool! 2. PLA: Compared to ABS, PLA demonstrates much less part warping and curling and, for this reason, can be successfully printed without a heated build plate. Details such as sharp corners and edges print well and PLA printed objects will generally have a glossier look and feel. This is the cheapest and most common material. 3. Flexible: MakerBot Flexible Filament is a polyester-based filament with a low melting point that makes it easier to extrude. Heat your print with hot water to reshape and remold it; the form will set when cooled. Little bit more expensive but useful for niche projects. 4. ABS: Compared to PLA, ABS has a longer lifespan, is more impact resistant, and has a more matte look and finish. MakerBot ABS Filament has a high melting point, so it’s suitable for machine or car parts. More expensive but useful for niche projects. 5. Dissolvable: Create 3D prints with complexity, overhangs, and movable parts never before possible. Place the 3D print in limonene and the supports will dissolve away in just 8–24 hours, leaving the print made with ABS Filament intact. This list is options that I found on the MakerBot website. I'm sure there are more options out there as well.
A: Just PLA, and you better not be dumb enough to buy the different colors.
