Awesome, thank you!

Thanks for showing your results. I have not tried ASA yet, but have done a few ABS and tried the same cool down as you, but did it in the end print gcode. I have had pretty good results with the SUMO enclosure. It keep the internal temp at 100 F. The cool down helped a lot, still had some minor warping, but was a very large part.

Nice, good to know.

Great video! Temperature is the major issue and the reason I cancelled my XL order. Enclosures are in my view, necessary to print these materials. Yes, you can get away with a tent or similar partial enclosure, but as you experienced you are really fighting the ambient temp. For ABS/ASA it doesn't seem worth attempting to print if your chamber temp is not at minimum 40c. On a multi thousand dollar machine Prusa still has no official enclosure solution. This is unacceptable in my view. Nevermind the actual VOC's that ABS and ASA release. You cannot effectively filter or extract them without a proper enclosure.

I should post an update on instagram.

I use a lot of ASA because of the temperatures and in my case UV Stable, it is the most stable for outdoor use of all print materials that are readily available. On Prusa's material guide, it is the only material listed for ultra violet. I use ASA-Carbon 15% for some parts with a Prusa MK3 in an enclosure at 50C. Works really well. Thanks for the tip on part cooling, that is a big deal. A material I am just trying out is Polypropylene-Carbon, very good high temperature properties and no enclosure needed, very low CTE (coefficient of thermal expansion), should be a very stable material. I have also found ASA needs to be kept dry or it starts messing up, it absorbs moisture quickly.

Very useful and clear video (well except for the super high resolution in the Prusa Slicer part, which made things illegible at 1080p, but you did explain everything that was on screen so no big deal really), this will smoothen the path for me moving towards ASA printing :) Thank you for adding temperatures in C as well as F too.

if you pop something and it starts to warp quickly put it back on the bed and every time its flattened for me. Could also slightly warm it with a torch on a flat surface, can help save a part.

I'm about to embark on this project (thank's so much for sharing your design so generously!) I print in an unfinished area of the basement that I can close off from the rest of the house. I plan to use the shower curtain trick and crack a window nearby for room ventilation. But wondering if I should prioritize one of the available enclosure designs before tackling this project. For the filament drawers I'm planning to prepare 6 units and arrange them 2 wide by 3 high mounted on a furniture dolly. (All my 3D printers are on wheels so I can rearrange things in my tight working space.) I'd like to have a plywood top for an extra work surface and wondering about supporting it. I could enclose the drawer units sides and back in plywood as well to support the weight and thought if printing a extra frame piece installed mid-way in each drawer unit would be enough. Any thoughts?

@RobertCowanDIY

2 ай бұрын

The frames really aren't meant to be load bearing beyond just the filament. I'd suspect it wouldn't be terribly sturdy. It won't collapse, but it will be 'bouncy'. BUT, you can just put some wood supports on the outside of the structure and use that to support the top. Since you have mounting holes on all surfaces, just do vertical supports on the outside to stiffen it up.

Thank you so much for sharing this video. I've been struggling with ASA on my Bambu X1C, especially for a model that printed well with PETG. Unfortunately, I've encountered significant warping issues with ASA, particularly on a crucial part of my project. Even preheating the X1C caused the ASA to stick to the build plate, but then the plate started to bend. Knowing that slowing down the cooling process was key to your success gives me hope. Although I'm not great at coding, I'll give it a shot. Thanks again for the insight. 🙏

@RobertCowanDIY

for sure! slowing it down and adding the gcode at the end should help out a lot.

My MK3S’ flow is set to 95% by default under Tune -> Flow, and looking online this is apparently because Slic3r-derived slicers like PrusaSlicer tend to overextrude. Is there a change with the XL/MK4 that turns that back to 100% perhaps? Do you need to reduce flow only for ASA, or for other filaments as well?

@PLr1c3r

3 ай бұрын

Every type of filament requires its own flow calibration. In orca there's a tab to run the tests to figure out the best results. PLA and ASA for example have different shrinkage rates and even brand to brand can result in slight differences. My rule of thumb is when getting a new brand/type run a couple tests (temp/PA/Flow) and you should be good to go without any issues.

I guess it begs the question, I assume that the Prusa has good main board and power supply cooling? I was thinking about attempting some "warmer" environments for my BL A1, I understand however that the chipset and the power supply both do not have cooling fans, not even a heat sink. I use a 4x4 closet for my printers on a bench, the temps get to 28-30 C with the door closed. I can monitor temp and video remotely. For warmer temps I can place a very small heater in there but don't want to induce heat issues on the main board. I appreciate your video, I think I will try some ASA and see if my setup is good enough as it is without extra heat and go from there.

Robert, thank you for the great content on the XL. I am looking to buy my first 3d printer for prototyping and possibly short runs in my machine shop, similar stuff to clough42. I am torn between the XL and X1C. I don’t mind spending extra for XL as long as it’s worth it but I do see a lot of people having issues. If you had to purchase only 1 printer to start with would you go xl or x1c. Thanks

It's a good question, but they are two completely different machines! If you NEED the larger format, or you NEED to print multi-material (not just cosmetic stuff), then the XL is the one to go with. If you NEED an enclosed printer or faster parts, get the X1C.

@RobertCowanDIY

The XL does zone heating, only heating the areas of the bed that are used for the print. This has worked out well so far. I should get a thermal camera to actually see this happening, but I can actually feel that certain areas of the bed are colder than others. It only seems hot/warm where it's printing.

I'm curious why you need to use ASA for this? Cool video; I've been wondering about ASA, but not 100% sure I need the extra it offers over PLA at the moment.

@@RobertCowanDIY sorry, I guess without actually owning both the XL and the Bambu with AMS I'm not understanding how they different. Both are capable for printing very drastically different materials at the same time. One is 5 extruders and one is just 1 extruder. Prusa slicer does warn the drastically different material bed temps when slicing. However, Bambu slicer does not seem to care if I slice a part with PLA, ASA, PETG all on the same part. Perhaps in practice that isn't possible with the current printer offerings.

I could do something like this, but I have around 30 of these to make and that would use quite a bit more material (and printing time).

Would be interesting to take the temp the other way. I've printed some thick wall, long PLA parts that always warped up at the ends. Maybe taking the part up above its glass transition temp while still stuck to a flat surface could relieve the internal stresses.

I had that too, but then I watched one of Slant 3D's videos where he showed a neat way to add thin round slabs that resemble Mickey Mouse ears to the corners (or anywhere you want) of such parts that act as brim but only where you want them to. They're also easier to remove afterwards instead of a full brim around the part. You can do that in CAD when designing the part or alternatively in PrusaSlicer as well.

Printed some full plates of small stuff on the XL. Used all three different plates as I had not done it before. Pla+ nothing fancy. There was a big difference when removing the pieces from the plate. The rough texture basically released everything when it was cold. Just wipe it clean of pieces. The almost smooth one was similar but held slightly stronger when cold. Now the peimsheet plate... it didn't release anything unless I warped the plate. Everything held on to its life. Haven't noticed this difference has been discussed too much. Textured surface releasing when cold may be good when everything works fine but peimsheet holding on may help when printer cools down in the middle of the print. Anyway, it may be a good idea for video to see if there is difference and how big it is. Same piece on the plate. Apply force until it poppes off Vs same piece on cold plate. Same with other plates. Should be easy to do with a scale.

In my experience, those top layer defects are indicative of too much plastic in too little space. You said you turned down the flow in addition to the temperature change. Id be interested in seeing something printed in the better temperature with the original flow. I would expect it to look overextruded.

@@RobertCowanDIY yeah thatll do it too, thats why I didnt call it overextrusion. Too much plastic in too little space can be caused by many things.

Potentially wonky suggestion I just thought of, but to get at least a somewhat serviceable temperature, I think some portable PTC space heaters can keep like 35 degrees Celsius, maybe even higher, and while that's not ideal temps, it could probably be enough for the XL especially since it has printed parts that might get soft with much hotter temps anyways. Like perhaps just putting one with a decent thermostat under the table the XL is on, could keep that whole shower curtain area reasonably warm, while not wasting too much electricity given its such a small enclosed space and it would only be running to top off the temperature so to speak.
