true, I use a mix of what others have said by trial and error to make support material thinner than other printed parts and angle support at least 40 degrees from print job printing, also adjust spacing or pattern of support to minimize difficulty of removing post print yet give required support so model prints as needed for best results. then buy special tools needed for quickest smooth removal of support without damage to model plus maybe other finishing methods depending on desired finish b4 sale/display. only way to eliminate much of this is using a 3D printer with at least 2 extruder heads and make STL files with ability to separate support into 1 extruder with a compatible filament material to the one used for model but the support material can be 'rinsed/dissolved' away as if never there. or use a powder type laser 3D printer which is very costly to buy and house in lab room with longer post print clean up time. like Shapeways etc use. the duel extruder types are not much more than single extruder type now making them the better choice for this unless for industrial use.
most 3Ders already have tools etc for cleanup due to previous methods being used for manufacturing our models required it also. most basic 3Ders dont print tiny items with lots of support so not an issue.
but as Carl said if you were mislead to think 3D printing was truly just like the Star Trek replicator to operate then. return it or pass it on to someone else and buy items like b4 for a few more years. as 3D printing for the public in that sense is not here yet. looking like a microwave dont mean easy as a microwave to use, nor as fast. e.g. a plastic police style whistle is closest print to that, yet it takes 25min to print using material, electric and labor/time which at best is a couple dollars and with minimal cleanup (breaking the pea loose from support) yet you can buy one mass produced in China from any Dollar store or bubble gum mach etc. I dont use my 3D printer for anything I can buy retail, or anything that sells for under 5$. I mostly print one off models and any sold average over $15 otherwise its not worth my time or materials.
Solidoodle 2 with Deluxe kit cover & glass bed with heater. and 2nd board SD2 used not 3rd and alum platform not installed yet still wood. also need cooling fan installed to board. use Repetier Host couple vers. Slic3r also have all free ware STL programs
