How do you do plastic surgery?

Posted · How do you do plastic surgery?

Just wondering if there are any good options to glue two narrow pieces of PLA together.

Looking into ways to connect two patches of 3d printed chainmail but I don't have much space to work with.

    I use cyanoacrylate glue for PLA, just the standard one. Usually after sanding or roughening the surface with a file. This works well. I also tried using an activator but that makes the glue cure too fast for good alignment. Thin glue tends to soak itself into tiny openings, so that helps covering the whole bonding area.

    Thanks for the tip. I did have canoacrylate glue in my possession but your suggestion made me research it a bit more. My current glue is a gel consistency and the dispenser tip was a bit too wide so it wasn't helping. But I found this glue on Amazon which is thin consistency and has special tips for precise delivery. I think that would help a lot.  https://www.amazon.com/gp/product/B00C32ME6G?pf_rd_r=4GWFVAQYWRGYJED5YB92&pf_rd_p=edaba0ee-c2fe-4124-9f5d-b31d6b1bfbee

    If you want to still use the activator with cyrano then spray it on "after" you've aligned the parts. It will harden any cyano that's oozed out and lock the piece in position while the rest cures.

    Thanks, this is a good idea. My current activator is not a spray, but a pen with felt tip, like a fluo marker pen. But I could probably apply it to the outer edge only, where glue would ooze out indeed, to get the same effect. I will try next time.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
