- Replace messy wire brushes on your 3D printer's gantry with silicone pads! No more filament oozing out while the nozzle is parked. We show how we upgraded the new IPEX 4-color printer with this awesome modification. You don't need to live with ooze on your 3D prints.

wow, how has no one else done this yet?
I hope this catches on as standard
I knew there was a reason I've been holding off making a nozzle cleaning brush! Thanks a mil!
Couple years ago I added a little sheet metal flap underneath the home position of my printer (just off the bed edge) to stop pre-print oozing and it works, but silicone makes WAY more sense!
I considered sheet metal, too. I don't think that's a bad idea. I was thinking of using the back of a heat sink to cap the nozzle so it might cool faster while parked, too. I was worried that I might eventually grind away at the brass nozzle.
For my application, little metal flap (basically a springy arm) with a silicone cabinet bumper on it would be perfect. Bumper can replace the tiny little bend I had to make to get the right height.
I just make my gcode start so it moves in front of the bed then back and cuts the extra off with the front of the PEI sheet. I think that's the same idea without extra piece.
Now that's a cool idea!
Super clever, and much cleaner looking than a chopped up silicone hotend sock.
I have a feeling there still might be some filament accumulating around the nozzle and the brush still might help.
Very possible. I think a silicone wiper or even a small brush wouldn't hurt to test out with this design. Having the nozzles capped by silicone when parked has been the biggest win for me.
That's clever well done
I've built a quad, a large double idex, and I've been using a combination parking mechanism. The parking carriage has a brush that the nozzle brushes over and then it parks on a silicone pad, it's actually easier to make. Get a silicone sponge, and a piece of silicone rubber, and use a couple of bolts to screw the rubber into a parking housing with sponge under it, the sponge is like a spring, I've done multi day prints and not even cool the inactive toolhead, and it works perfectly fine. There is minimal oozing because the inactive toolhead is sitting on a sponge spring silicone pad, and when it's needed, it runs over the the brush and to knock of any gunk. The brushes last longer, basically replaced 1 or 2 out the 4, in the close to 5 years I've been printing on this machine.
great suggestion!
Thank you for making this super clear and to the point. Awesome solution!
I might have to try something like this. Looks interesting anyway.
Brilliant solution!
fantastic idea dude!
That is a very simple fix, awesome video mate👍😊🇦🇺
Nice one. Definitely going to upgrade my parking space with this nifty solution. Also, well worth the subscription. Keep'em coming.
This is an amazing idea!!
I did this last year on my toolchanger with hemera printheads. Sadly the heatflow in the hemera is such that the heat travels too high up the heatbrake, and my hemera gets clogged.
Edit: I did design and print a mod for the hemera where a servo would move a piece of thin silicone/fiberglass tape in front of the nozzle. The mod also addressed the hemera cooling problem also, though I never ended up commissioning it.
great feedback! I'll keep an eye out for similar issues
That is brilliant!
Great idea
Dude your printer is bonkers
Great wiper idea and video! Subscribing to see more!
Only one of my printers has something like this, it's a dual color machine and the nozzle wipes across a rubber flap every time it changes filament and purges the nozzle. It doesn't make a purge tower, it drops it onto a little slide so it ends up on the table next to the printer.
That sounds like it could work really well.
this is a really smart solution for parked heads! question for you- how are you handling purging on the chimeras? normal IDEX printing doesn't need a purge since you have two independent extruders, but since you're mixing two in each nozzle I imagine you're purging. Are you purging between every color change no matter what or are do you have a way of specifying a purge between A->B and C->D, but not any of the other swaps (AC, AD, BC, and BD)?
They are 4 independent nozzles with their own hot ends, so it's ok to let one print while it's partner is idle. A change to Marlin firmware was needed to make sure changes like A->B wait for A to cool sufficiently before B can begin printing. Changes like A->C can be more immediate since A will go park. Overall, prints take longer if there is a lot of cooling pauses needed, but no purging is required. At some point, I'd like to try and optimize the slicing so I can avoid the cooldown needed by preferring to change from one IDEX side to the other over changes between nozzles on the same side.
incredible
do you have to change the software code for this to swing over the print plate?
Would you happen to have an stl for these? would be pretty handy for tpu especially!
the dimensions are really specific to my 4-nozzle printer design, but I'm happy to share. I design these parts in Tinkercad. Here's the link to the parts. You can resize them to your needs and export STLs from there. www.tinkercad.com/things/69iy3DGPvfW
Noice! Im usually just near by with twizzers ready to grab it before it get to the part lol
How did you fix the silicone pad into place, did you use specialty silicone'glue? ..cause no other glue works on silicone
I just used more of the same red silicone. It will adhere to itself and to the plastic tray I hold it in.
@@mightystudiosvids Interresting. Thanks!
Can we get alink to you silcon mold and mount models?
I added the link to my Tinkercad models to the description. Please note you will likely need to customize these to fit your printer.
FYI, do the RTV part in well ventilated room
