Stratasys worth the price over RepRap style 3d printers?(self.3Dprinting)
submitted5 years agobyfly2future
if you had a budget of 30k to get involved with 3dprinting would you buy 1x professional Stratasys machine or buy multiple RepRap style machines?
Im wondering what exactly you are paying all this money for with a Stratasys machine besides the soluble support system? is the software on the Stratasys machine so much better than the opensource software used on these RepRap style machines?
From researching it appears that the Makerbot/Rep-rap derived printers are producing parts just as good as the Stratasys systems… or is this just a lot of hype and the reality is that the parts quality is way different amongest these machines?
Being the technology is so new, Im just unsure if right now is the right time to buy a printer or give it another few months or so to see what other options come up with higher resolution, faster printing, etc.?

The difference is how much time toy want to put into the printer. I convinced my last company to purchase a u print (one of Stratasys lower end models). It was awesome. No matter what designs i sent to it, they would come out fine (within the limitations of layer thickness, xy tolerance, and minimum feature size). Literally, the only thing that i needed to do were reload filament and occasionally change print heads. I still long for the soluble Support system as i sit here with my reprap.
With that being said, you trade off the ability to refine the machine for ease of operation. You get the layer heights and tolerances that stratasys offers. You pay 10x for filament over reprap. You will probably want to buy into a service contact as well.
The bottom line is that stratasys is plug and play while reprap requires much tinkering. Stratasys is EXPENSIVE while reprap is cheap.
If i had 10k to blow, i would get a strstasys mojo but i would continue working with my reprap as well.

Hello! My school actually has a Dimension printer, and I actually believe Statasys and Dimension have merged into one now.
Here are some critiques from my point of view, as a student who has used it for 3 years now, and someone building their own reprap.
Large Build Area (ours has 12x12x12 inches)
Heated build environment is better for ABS prints, stops ABS shrinkage
Pretty much print and go, easier to operate
Filament swapping is easy, usually cartridges.
Can use soluble support material, and non-soluble break-away support that also works well
Not as good layer heights. Not bad tolerances mind you, but just not quite as good as a reprap
Commonly much slower than the higher end reprap designs
Material is crazy expensive. $250 for 5lbs of ABS, where it costs 95$ for filament for repraps. And no, you cant get around that. Due to a serial code and electronic filament level tracker in every spool, each one gets a unique ID and memory of its fill level. Respooling it would lock the spool out, I believe. There are firmware hacks, but that tosses the warranty fully out the window
Restrictive software. Our layer heights are limited to 0.23mm and 0.25mm. I have heard it can do much better, but again, this requires firmware hacks
In short, big machines are expensive but reliable, with massive build volumes and ease-of-use in mind
Repraps are the antithesis of this, with smaller build volumes (commonly 8x8x8 for bigger printers), higher precision and speeds, but require software and hardware tuning to achieve the best results.
I personally favor RepRaps, but I will avoid introducing bias as much as I can

do the rep raps use soluble support material like the srarasys?
MendelMax 2.00 points1 point2 points5 years ago(2 children)
You can buy it, yes. Its called PVA but is about $56/lb instead of $21/lb. But Im sure the price from Stratasys is not cheap either

my work is looking at the stratasys u prints, which more expensive seem the best solution for an education setting, nice and enclosed no chopped off fingers
MendelMax 2.00 points1 point2 points5 years ago(0 children)
Well, chopped off fingers arent a worry, but burns are. The hot end reachers 165 Celsius, and the bed 65-100 Celsius depending on material. Some can be bought with enclosures; I recommend Solidoodle 2 or 3 with enclosure. And it pains me to say this, but even the Replicator 1 with dual extrusion or Replicator 2 with dual extrusion (if you wait for it to be released) would be a better choice. Just about any enclosed 3D printer would be best, I guess. And cheaper for material, so would allow you to use it for more stuff in education.

Dimension and Stratasys are one and the same. Dimension is a line of their printers.

If you have 30k to play with, why not look into photopolymer-style printers? You can get far better resolution (generally), and in some cases excellent build envelopes as well.

Im a salesman for Stratasys printers, and I just recently went to an event where I got to see all the Makerbots/RepRaps/LulzBots working, and every part I saw printed was either severely warped or had some other bizarre quirk that forced them to reprint. So, I mean, if youve got the budget, then Id save yourself the pain of dicking around with a lower end printer.
And for the record, Stratasys Mojo printer is only about $10,000 🙂
