Say hello! Tell us what library you're with and what printer you're using!
We have been blessed with multiple 3d printers by donations in addition to our original purchases. But we now have 7 printers and all of these are 5 different model/brands. Yikes!
I am hoping to find a simple networked interface for users that, to them, seems device independent. IOW at their desktop, on our local lan they could choose any one of the 7 printers, and not need to walk over a memory card to the printer but print from at their PC. This would also free us up from having a separate laptop for each printer (e.g. running CURA for printing). So I have been considering OctoPrint, AstroPrint, PolarCloud, and now Repetier Server. All of these can use Raspberry Pi's as controllers. Our constraints are (1) to keep costs low, and (2) I am not a programmer, so minimal low level IP/Linux manipulation is a big plus.
Anyone out there trying to manage more than 3 printers in a public setting? What solution works best for you?
I'd thought I'd just share that we use Springshare's LibWizard to make patrons aware of our policies on 3D printing, get the information we need from them, and to submit their STL. We print in submission order, so this effectively becomes our print queue as well. Here's what we say and ask for:
Please review our Acceptable 3D Printing Guidelines before submitting a print job.
- You cannot use the 3D printers to create materials that are:
(a) prohibited by municipal, provincial, federal, or international law;
(b) unsafe, harmful, dangerous, or capable of posing an immediate threat to the well-being of others;
(c) obscene or otherwise inappropriate for the Library environment;
(d) which may violate another's intellectual property rights (for example, the printers and scanners cannot be used to reproduce materials that are subject to copyright, patent, or trademark protection).
The library reserves the right to refuse any 3D print request.
The printer queue is a first-come, first-served system.
Printers are operated by library staff only.
Printing costs are $0.10 per gram of material used. The cost of the print will be charged to your library account. Unsuccessful prints will still incur filament charges. Refunds are not available.
The Library is not responsible for the functionality or quality of content produced on the 3D printer.
- Items printed from Library 3D printers that are not picked up within 14 calendar days will become the property of the library and may be disposed of.
First Name: (required)
Last Name: (required)
Library Card Number (required)
Please indicate any specific resolution, speed, material colour, or support requirements.
By default staff will print using the settings they believe will create the quickest, most reliable print.
My library has a replicator 2x. We thought we canceled a print after preheating the build plate and extruders a second time. I returned hours later to find the Kapton tape burned off where it tried to print again. The base layer of the thing it tried to print appears to be slightly burned onto the plate's surface. It doesn't feel scratched or warped but I can see where the extruder repeatedly tried to print layers after it failed.
I haven't tried to remove the old and apply a new Kapton sheet yet (I'm scared!!) Has anyone experienced or seen this before?
My library just upgraded to a Lulzbot Taz 5 with a flexydually print head. I just started experimenting with printing flexible filament. It's awesome! If you have younger kids using your printer I would highly encourage using it. So many times with ABS and PLA a kid would print an object and it would break before they even left the library. Flexible prints beg to be played with! Anyone else using flexible filament out there?
Last night we set a large print (17 hours) when I came back this morning I discovered the print failed (4th gen so it kept going...) and a large lump of melted filament around the extruder. I removed the filament and heated up the nozzle but none came off. I'm afraid to chisel it out with tool as I may damage parts of the extruder. Any ideas on how to melt this this lump off?
Looking for an easy print to introduce patrons to your 3D printer? One of the awesome teens at my library designed a generic book keychain. The best part is that he's willing to remix the keychain to customize it for your library! Check it out here: http://www.thingiverse.com/thing:336548 and contact him directly if you want him to put your library name on the book.
