The following statements and opinions are solely my own, and do not reflect the views of my employer (Bosch) or their affiliates (such as Dremel).
I have not had the opportunity to work with an Ultimaker, Lulzbot, or Flashforge machine, but I hear that Ultimaker is a solid choice.
I have had the opportunity to work with several others in this price/volume range, however, and so I can offer opinions on those:[ul]
[li]Makerbot[LIST][/li][li]Previous generations were iffy, but the latest generation is solid.[/li][li]Pushes out of your price range ($2500 at last check).[/li].[/ul]
[li]FABtotum[ul][/li][li]Amazing concept: 3D printer, 4-axis CNC mill, and 3D laser scanner all in one.[/li][li]Unrefined product, poor customer support.[/li].[/ul]
[li]Dremel[ul][/li][li]Best success rate, least calibration required, and best customer support out of any 3D printer I’ve worked with-- and that’s just the 1st-gen model (3D20).[/li][li]The 2nd-gen model (3D40) is about to launch in a few weeks-- although it is being positioned as the 3D20’s big brother rather than its replacement.[/li][li]Neither of the Dremel printers can use ABS filament, but I don’t miss that capability at all. Especially in an education setting, ABS is more trouble than it’s worth![/li][li]Note: Both of the Dremel 3D printers are only labelled for use with official Dremel filament.[/li][/ul] [/LIST]
