In my last video I wasn't very impressed with PLA Support Material, but after a few comments instructing me of how it's supposed to be printed, I decided to give it another chance. So here's how it went.

Wow, I do not have the same issues and use this product a lot. Perhaps it is my setting that are different then what is recommended. I do set the support material interface however I do not use the other recomended setting i.e. zero interface. since I print a lot with .2 layer hight I use .22 gap and it works great.

@TapticDigital Месяц назад

@@chrisc9213 interesting, I’ll have to try it with a small gap and see if it helps!

@cerberez1 2 месяца назад

weak layer bonds are probably because you weren't purging enough in between the two filaments... if something that doesn't stick to pla gets mixed in with pla, the pla will have trouble sticking to itself layer to layer.

@coalachaos6486 13 дней назад

Remove it with the help of a heat gun. Then its as good as PETG. However, the PETG may cause colour irregularities along the layers where the support PETG is printed. You would not find this problem with the support material

Interesting. I've had (mostly) very positive experiences with that stuff. I don't bother using it if printing in PLA-CF (eSun) or PLA Metal (Bambu), as those supports seem to break away without any real effort. I suspect your troubles were largely due to the fact that the Master Chief miniature is pretty intricate. I've mainly used it on very flat overhangs. I recently used a bunch of it on a clock I designed for my office that needed a ton of support in the back because of my lousy (in terms of printability) design. Clock looks great, ran in one shot out of the AMS, so no need to glue/assemble, but the supports were a lot. Yes, there was a bit of scraping to get the more difficult bits off, but I found that once I got a good bit started, a bunch came with it. Like you, my first times out were using it for the full support, and it wasn't great. When I changed to the interface-only, with 0 z-gap and holding up actual flat surfaces, it's great. So, a mixed bag? Yeah, probably.

I also got some of this support material with my x1c maybe 1.5 years ago or whenever I bought it. I still have most of it, tried to use it once. But like in this video the model snapped in half at that layer. But I don't think it's cause it cooled down, if it was it would also happen when you use multiple colors. Which I'm pretty sure is not the case. This support material seems to severely weaken the layer adhesion when it gets mixed in with regular PLA while at the same time fusing to the model in some spots and being impossible to remove.

@TapticDigital Месяц назад

@@atnfn that was my other issue, because it had to do a filament change it allowed the previous layer to cool more than others. So you end up with a visible line on the print of the layers that cooled differently.

I would offer one more suggestion that helped me print better with this material. Purge values; this helped reduce the mixing of materials at the interface and prevented my models from developing weak spots from cross material contamination. Using a value of 750 switching to and from “support pla” material made the model quality similar to my build plate and the interface peeled off without tools (although with more force needed then a petg interface)

I am going through the same learning pains right now. PLA support works... but only marginally better than just printing in all PLA with all the issues you're pointing out now. I'm going to go place PETG order now.. begrudgingly. Nice video, thanks for sharing your findings.

@TapticDigital 3 месяца назад

Despite what I said in the video, I still haven’t full given up. But I am quite disappointed each time I try.

@tharpe12 3 месяца назад

@@TapticDigital Same here haha. I'm working on a model that has several delicate features that are also overhangs (a non-ideal combo) and even manually setting the support locations to minimize the amount of contact the features are breaking off so I started to investigate a different support methods. The story seems pretty consistent across all avenues though that PETG is worth a shot so I'm going to try it out this weekend hopefully when my PETG spool arrives. I can share my results here for posterity. I think PLA support has its applications, but if you are doing anything with delicate features or considerable overhangs it appears that PETG may be a better (and seemingly cheaper) solution.

Be aware there are 2 products for PLA supports from Bambu Lab! One is pretty old (came with the printer) and does not work very good. Seems like you have that. And the new one just works. Link to their website is broken right now else I would put the link in here.

@@DanielSchweinert I still need to try their new version and see if it actually works, until then I’ve been pretty happy with PETG as a support interface

@DanielSchweinert 15 дней назад

@@TapticDigital I suspect it is PETG :-) since it's advertised for PLA & PETG as support material. LOL

I recently bought X1C and it came with the "Support for PLA/PETG". It is much better than this one in the video. It's extremely easy to remove. I'm guessing this is an older version since it looks silver colored, while the one i got is translucent.

@TapticDigital Месяц назад

@@changeformer yup! They released the new version about a month or two after I got my printer.

Arent you supposed to disolve the support for pla in water?

@TapticDigital 24 дня назад

@@Jirisvejda6 nope, I had at first thought it was just PVA which would dissolve, but after sitting in a cup of water overnight it did nothing

@Waneklap 23 дня назад

The PVA support material has to be submerged in water. It dissolves in water giving you a clean breakof

@TapticDigital 22 дня назад

@@Waneklap that would work, if it were actually PVA. Compared it to PVA from Makerbot, bambu support wasn’t affected after 12hrs in water while the Makerbot PVA was completely gone.

@@TapticDigital I used Bambu Lab PVA support material last week for the first time. Used it as a support interface material only, the rest of the model and support structure was printed in BL PLA Metallic. I used the PVA fresh out of the bag, no drying, which resulted in some severe spider webbing at the top of my model, a Pythagorean tree. After printing I just dunked the model, while still on the PEI sheet, in a bowl of water for a workday. The spider webbing had completely dissolved and the other support came of real easy. Any remaining PVA stuck to the model I could easily rub off with my thumb. It was a good experience.

Nope! I actually tested it in water as well as alcohol, just to rule it out. It does make it separate from PLA easier, but where it does stick it stays quite firm
