Such a handy trick! Sacrificial bridges are like the secret sauce of designing for 3D Printing... once you know about them it really unlocks a tonne of design potential.

I know I am quite off topic but does anybody know of a good place to stream new movies online?

This should really come as a feature in the slicer itself. Feels like a pretty simple thing to check for while slicing, it’s basically just extending straight lines or checking for where a plane intersects. If done in the slicer the thickness of the sacrificial layer could also be reduced by reducing the flow rate while it’s ”bridging”, making it easy to remove even if you print very thick layers.

Could easily be implemented in a slicer. Yes, supports are evil. Cheers!

I normally use 45 degree chamfers everywhere, but this is so much better. Thanks, will totally be using this technique.

Excellent. I while back I did the same while printing parts for a Bontech extruder. Worked great as you stated. Thanks

This channel is a goldmine. Thank you!

You can use also sacrificial thin cross walls to support bridging parts to improve the finish quality :-)

I do this in some of my prints. It helps when you have a part that you can't bridge normally. Think of the overhang part being the corner of a cube. Nowhere for the bridge to go. Uses way less filament than normal supports as well.

I know, it's been a while since you published this. Just stumbled over it. It took me a while to fully understand the ingenuity of this. I tried it with a similar part I just designed in F360 and this not only saved filament but also time. And the results are great. Amazing!

this is always helpful, and it keeps on being a good tip. i first watched tips about sacrificial layers for bridging from makers muse videos, it is so handy and it should have more people doing videos about it. it was great showing the perspective of making several parts. also bringing things up in the reference of making several parts, clean up and time becomes prohibitive. good video. thx!

Nice video! I did this in my designs for years not only on horizontal layers, but also on vertical shells, works great as well 😉

Gosh I learn something new with each of your videos! I had seen this technique from Angus but it didn't sink in how useful it was or easy to implement, yes will be trying it out next opportunity.

You don't need CAD file for this if you use PrusaSlicer. It allows you to add primitives (cylinder, box ...). Make it 1 layer high and place it where the supporting bridge should be. Although I have to admit that doing this in CAD is much easier. But in vast majority of cases you just don't have access to the source file (yes, I'm looking at you, Thingiverse)

Expected it to be a tip I already knew, got pleasantly surprised!

This is indeed very smart and simple. Great tip!

Good info, since I was having this exact issue with some PETG that I like and didn't want to use supports for the design. Thanks for the great tip!

Great tutorial Joe. I've been using sacrificial supports for some time with 100% success .... so far.

Great idea for harder materials such as TPE, PetG and Tglass as those materials are difficult to remove supports.

Cool little trick, I already know at least two projects I'm working on where I wish I knew about this before. Both parts require supports to print, but at the same time they're very difficult to print with supports, this will simplify things a lot.

Wow, how have I not thought of this before!? Thank you!

Thanks for the tip. Tried it and it worked a treat for what I was doing.

Awesome video! I do use sacrifical layers but mostly for small screw holes, hadn't thought about using it for other things! Also, the mural looks so awesome!

Thanks for this video. A very good solution to avoid plastic lost.

Awesome Tip ..... thx. I have had a problem with a current knob design that this will help.

Great trick! 1st I've seen this from Angus. But this explanation and the reminder are pretty good! Thanx.

i use this all the time. love it

Very helpful and useful tip for designs and printing. Thanks!

Very neat, I love learning new things.

Thanks for the advice. The community is good!

Excellent idea. Thanks for sharing

Thanks for this trick. Is a must for less waste. Continue the good work.

Great! Many thanks for the idea. I gonna try it with my next print

Great video very interesting. also great to see the mural up and running in a video 👍

so simple and yet brilliant . thanks .

Cool! Very interesting trick. Thank you!

Very practical and easy idea! Thanks for sharing.

Thank you for the great tip. I will definitely be trying this out. Cheers 👍😎🇦🇺

Great Tip. Thanks Bud.

What a great idea! Thanks for sharing!

There is a easily missable standard Setting in prusaslicer that makes Supports EXTREMELY easy to remove. Just change the Z Distance from 0.1 to 0.2 in the Supports tab

Thanks for sharing. This is great!

awesome!! i'll try it!

This is a very neat trick, will definitely be doing this in future.

Cool trick! I'll definitely try this out.

Great tip. I often forget about this.

thank you so much! so easy and so effective.

This is genius. Thank you for sharing. I simply don't want to use supports so it limits/complicates my designs. With this trick I have more options. I have to try this at some point.

Super trick and advice!

neat trick, will be very helpfull for many prints

Never thought about this ... thanks

Great tip thanks

Great explanation!

back on form joe ..fantastic video well be trying that

Excellent tip!!!

Great tip. In the past I've resorted to splitting some items in two in CAD, printing, and glueing back together.

I still like this option in a lot of cases since the glue has the potential to add some strength and for structural components it can be advantageous to print portions in different orientation to avoid bond strength issues.

Yeah I think I first saw the idea from Angus (Makers Muse), but you make a good point about it is actually faster to use sacrificial layers, since you aren't doing additional perimeters.

this is actually big brain stuff. very cool!!

Хорошая идея! спасибо

NIce video. It heled me lot and also reduce the amount of support needed in my current project.

Nice tip! Thanks!

I picked this tip up from Angus (Maker's Muse), and often use this on parts that I downloaded. Usually I only have the STL and I'm not experienced in modifying meshes like this, so I add these 1-layer covers to the holes in PrusaSlicer. Doing it in the slicer (even for my own designs) also allows me to choose at the slicing stage what layer height I want to use and then add the hole covers at the correct thickness then. Especially useful now that I'm using adaptive layer heights, I can find out the right thickness after I've applied the adaptive layer height tool. For counter bored holes smaller than I can fit my deburring tool into (like for M2 hardware) an appropriately sized drill bit makes easy work of cleaning the finished holes. (For example, 2mm drill bit for for an M2 hole.)

Pretty great idea If you needed to do a large area you could still use a support wall also a minimum thickness at the mid point of the widest point of the sacrifice layer its faster and cheaper to do your way of this thank you now I have a new tool in my box

Omg, dude! thank alot!

Great tip!

Smart... Thanks a lot!

Had to look up what a borrowing tool was, thanks for the link.

Damn! I thought I had seen everything. But this is great! Cheers, mate!

Cool trick!

Neat little trick!

Will try

Отлично! Спасибо!

Such a neat trick to avoid support

Great tip.

Excellent. I didn't know that thin a layer would be enough support.

Nice tip. Well explained. Thanks. Sometimes supports are, in fact evil, and other times they come off easily, and hardly leave a mark. It is hard to know what settings to tweak with supports to improve them. More testing needed, I guess! :)

This blows my mind.

smart .. thanks

Amazing, with id known aboutthis before my last print. 18x 19mm bearing inserts to clean out......

Great job

Nice tip. Notice that, in the first piece, since you're already adding a support part in the design (the sacrificial layer), you could also make an inner ring to sacrifice as well, whose outer wall would be exactly the diameter of the piece innermost ring or just barely shorter (enough to let the cutter blade slip in between later on and as tall as the sacrificial layer, so you'd be still bridging to make the "balcony" bottom layer, but the bridging distance would shorten so it'd be more firm, and you may even increase the piece size.

Freaking brilliant

Cool tip

I occasionally modeled supports in my designs, but I never had the Idea to make use of bridging. Thx!

Not sure if it was your accent or not, but it sounded like you called that tool a "burrowing tool". Its actually a de-burring tool, for removing burs. But works a treat on 3d printed parts, also good for trimming any elephants foot effect on bases of parts.
