3d printing? Answered

Hi every body i saw today al ot of 3d printers videos and a lot of printed things , so i get really convainced to buy one , i really liked the makerbot replicator 2  ,is it really good quality printing? can i print projects working and moving without assembly , and i need some advices about the good and bad points about this printer  , and i would like really to know can i print a mechanical object that contain movable parts in one print and get it working , and if there assembly what is the process , at the 3d library i found this engine http://www.thingiverse.com/thing:34701 is it one part working print project or i have to print a lot of pices and assemble them , and what about this one http://www.youtube.com/watch?v=1yFI_tsuPPw is it one piece too, i couldnt really understand how the pieces get assembled ,can any body help me , give me more informations websites!!!!!

i will really appreciate your help!!!!


No consumer level printer (under $5k) will be able to print objects with working and moving parts without assembly. You would have to design and print the parts so they can be assembled later. Most consumer grade printers have very similar specs and can do a decent job of printing ones you have the machine well calibrated. There is typically a lot of calibration needed to refine your prints.

3D printer quality is good enough for prototyping an object but not quite good enough to use as a final production. Only printers that run in the $100K range that use polymers and laser lithography to build the layers will be able to make production grade items.

The file you link too comes in multiple parts that you will have to print and assemble. Looks like it has about 8 parts. The pictures show the individual parts that will need to be printed. The engine in the video is also a multi part object that takes some assembling. Any item you decide to print should be pretty easy to figure out how it goes together or it will have some helpful hints as to how to put it together.

i didnt really understood what do you mean , the makerbot replicator is for 2500$ thats not very cheap as other 3d printers like :up !, 3d cube, and many others 3d printers, when i tried to compare finishing i think its the best desktop 3d printer, here is the site take a look https://store.makerbot.com/replicator2.html
there is a lot of objects already printed what do you think about them?
do you think that the v8 engine was printed with this type of 3d printer , what about other movable 3d printed objects

As far as 3D printers go the Replicator is one of the more expensive consumer grade printers. But nothing compared to the cost of the professorial grade printers. Yes the replicator 2 is one of the best desktop printers. It will make any model you want once it is fully calibrated.

thanks for your answer , what about the cube x 3d printer , is it better than the makerbot, i dont really worry about the 2 colors extruders in the cubex , but i really wanna to see a video of assembly of movable parts as engines,articulations .
what is the difference between PLA FILAMENT and ABS wich is cheaper?do you know any sites that sell them cheaper than the main site.

thanks i am sure that you`ll answer to my questions
PS: really didn't understand what does filament means , is it a system to joint between movable parts at printing

Look at what extruder each uses and how thin it can extrude the plastic. The thinner the finer the details you can get in the prints.

thanks but you do you have seen any video about assembly of movable printed parts as engines,articulations . i realy wanna to know how harder it is it will work every time

thanks appreciate your help

Putting it all together is fairly straight forward. With the thingiverse link you offered you should be able to figure that out on your own. As long as your printer isn't messing up the print and everything turns out good and strait it will go together just fine. If things are a bit tight you can always sand the piston down a bit. The V8 is more complex but if you understand how engines work then putting it together will be easy enough. These are not overly complex items otherwise they couldn't be printed. Attach the pistons to the crank shaft and fit the pistons into the casing.

The finished product will depend on how well your keeping the system calibrated and monitoring the print as it goes so you can stop it if anything starts going wrong. Even the best desktop systems have there little quirks you have to get use to and learn to work with.

and from experience, the thinner = the more of a pain in the ass tweaking it to get things lined up.

I have a friend with a replicator, another friend with rep2, and they're both very dissatisfied with the results; quality, repeatability and outright hardware failure being the primary causes for concern.

Another friend with an ultimaker was fairly satisfied but it took a TONNE of tweaking to get it right.

I personally own a hadron ord bot. It's an entirely diy model based on ramps drivers and extruded aluminum frame. I've tweaked it for a year and it is yet to print anything (my laziness).

Another group of friends build a lot of prusa bots. They are the most productive so far - probably because they worked the hardest on theirs tweaking them to perfection.

Find your local hackerspace and or 3d printing group and see whats on offer.

Lastly, consider the new generation(s) of dlp visible light hardened polymer printing which offers many benefits that you just can't get from deposition methods used by ALL the other diy printers.
