this is one long print. would anybody here print “personal use” objects for so long? (if it’s an order well… it’s business)

Printing… 82 horas
Why not - that’s what we built our printers for … Not everyone runs a business off their 3D printer - most use it for personal item - large or small.
Speaking as a person who doesn’t have a 3D printer yet…my concern with an 82 hour print is if something goes wrong at 70+ hours…lot of time and expense for a failed product. I think a lot of consumers would be wary of leaving technology like this running for such a long time. Generally from what I’ve read, successful prints still seem to require a lot of attention/fine tuning so it’s not quite like starting the print and coming back to the finished product for large prints.
@Dushyant_Ahuja so… You’d make an object that takes 3&1/2 days do complete because “that’s why you have a 3d printer”? OK. Not even as an experiment does this make sense. Again, if it’s being paid for, 5 days… 10… Who cares? I’m just thinking that objects which take this long to print can be made in a different way.
Yes. I built a big printer (280x280x560) to make big prints. So far may longest running print has been 18.5 hours ( very detailed lightsaber handle). When the bigger jobs go in its just a matter of changing rolls.
yes I often do!..
@Adrian_Ciubotariu not sure why it doesn’t make sense to you. I have a printer with a print area of 15" cube (nearly) and prints that size typically take days and not hours. Why would I build a printer this large if I didn’t want to print things this large. 3D printing allows you to create objects and shapes that would otherwise not be possible using traditional manufacturing processes. The print that you linked to is a typical example - how would you go about creating this piece easily. Not everyone has amazing carving skills, or access to Cnc machines that “may” be able to do this. We bought / built our printers to do just this. It might not make sense to you - it does to me (and others)
sure. Prototypes and machine parts for them personal workshop often take several days to print.
@Dushyant_Ahuja actually a 3D printer IS a CNC machine. You probably mean a CNC milling or turning, eroding or laser cutting or water jet cutting machine.
@Marcus_Wolschon agreed - I meant CNC milling or laser cutting.
I don’t know, call me a coward, but I personally don’t feel comfortable running my printer for such long stretches of time. Longest print I’ve ever done was 3.5 hours, and I was a nervous wreck the whole time.
In general, if the printer is happy after 3 hours then it should be good for much longer – if the model’s likely to print fine then I for one wouldn’t worry about it taking a long time. My main concern on long jobs is “is there enough filament on the spool?” If there’s definitely enough then I relax and leave it to it.
@Tom_Nardi when I had a 12 hour print fail in the last hour due to a hardware failure, I became cautious for awhile.
@Dushyant_Ahuja well, with a print volume that large you’d also have a proper extruder, able of pushing enough plastic so that the print takes a lot less. if one prints parts with 0.1 or 0.2 mm layers only wit a 0.4 nozzle then one’s not really going about it the right way. one can have 0.1mm layer thickness even with a 1mm nozzle, since we’re talking about large prints.
this is where I was going at. what use is printing with a a small nozzle very large prints? and don’t tell me “detail”.
@Adrian_Ciubotariu I will say detail. I have a 1mm nozzle to print out large parts, but many times you want something intricate enough for a 0.2mm nozzle with 0.1mm (or even 0.05mm) layers.
@Tom_Nardi I had that within my first 5 printers over the years. They would fail at any time.
The last 3 are so reliable that this is no longer an issue. Nozzles and temperature management inside hot ends have really come a long way despite the enormous diffusion of effort and unnecessary double, triple and quadruple development in the early years due to RepRap never having been properly maintained/curated.
Listening to you guys talking about volume and build time makes me nervous. My longest build wasn’t the largest I have done, but a 62x62x97 hollow box with relatively simple features. (http://www.thingiverse.com/thing:28434/) It took my Ares >8 hours at 0.2 layer thickness and 0.4 extrusion. Is this overly slow? At this rate, it won’t take much intricacy to push build time to days.
My longest prints have been for personal use. 32 hours I think is the longest I’ve done. I regularly print for business orders that take 12 and 24 hours.
I would not want to do more than a 12 hour print and I would only do that on a weekend or other day off work. I would probably want to split the print up into smaller prints and wonder if the settings are right and then wonder if the time estimate is right.
My longest personal print was 42.5 hrs. I’ve installed fire detection and suppression in my printer room though as I do get nervous about thermal runaway.
I’ve also ran several batch jobs that were print, remove from build plate and start again. I ran one of those batches for a little over 2 weeks with just the downtime between removal and re-prep. I am currently looking for options to convert to DLP Resin printing as this seems like a much less fire prone method and resins seem to be improving significantly.
