Prusaslicer bridging overlap This behaviour was not present in PrusaSlicer 2. The bridging lines being too close to Turn perimeter into bridge? Hi everybody, I'm playing with a fiddly part of a print and noticed something that I don't understand in the slicing process. 5. Automatic anchoring of bridging infill. This way, I can use 15% for the top and bottom layers and 25% for the bridges to ensure As of right now, bridging on PrusaSlicer doesn't seem too difficult when your bridging from one structure to another. Cura Screenshot. Prints are all See prusa3d/PrusaSlicer#9999. 2 and . The Max volumetric speed setting in Compensated, the flow is . Thank you very much. As @Neophyl notes, there is some overlap between wall extrusions for strength. 2mm bridge, the other 0. 4 nozzle with layer height of 0. 6mm Bridging flow multiplier: 0. I also made a true bridge i. Vaciar todo. You will need to reduce speeds significantly to avoid overrun your hotend's capacity. 2 mm height I have to set my flow ratio in a certain way, which gives me 0. The printer has a 0. I don't think that matters so much since I've said what is the problem, this is my first time using Prusaslicer ( I have been using Yes, you need to play with the perimeter number, but it should be less than the model thickness at the point where the bridging has to occur. 2mm line width with 0. https://imgur. I wish this is part of PrusaSlicer. Bridging overlap on previous layer question. I have been having issues with the first layer of bridging overlapping the wall. yess! there should be at least a bridge wall overlap at minimum. My Try enabling Print Settings->Support material->Options for support material and raft->Interface layers (I use 3) and experiment with Interface pattern spacing (I use 0. IME, at 1. 0-alpha3+win64-202109301506 Operating System: Windows System Architecture: 64 bit Windows Version: Windows 10 (build Printers are Kingroon KP3 and As you can see in the pics, i have a big gap between the infill and the perimeters. Normal layers have a small overlap between filament path for them to bond together - but that creates pressure and is the External Perimeter Shells Overlap Setting with PrusaSlicer. You can try for a multiple of extrusion widths, . My Issue To start off, I'm using PrusaSlicer version Filament: MatterHackers Pro nylon Nozzle: 0. com/deiMEDA as can be seen here, the bridge infill has no overlap, but the solid Is there a way to force more overlap to make the bridge layer stick down to the previous layer, before it extends into free air? I've been playing around with adding ribs over There are three key settings for printing good looking bridged layers: PrusaSlicer settings, speed, and cooling. Now let's enable "extra perimeters on overhangs" and we get this: I didn't realize that PrusaSlicer. Thus I propose an addition of a second Check your "Infill/Perimeters Overlap:" by default it's set to 25% if you haven't altered it, then turn it up to 50 or 60% and see if it helps. prusa3d. 5mm thick, the problem is less noticeable. Notifications Clear all Bridge overlap is not catching Ostatni Post RSS CUKIO34 (@cukio34) Active Member. Screenshots to illustrate the issue below My proposal is to add an option for specifying the infill/perimeter overlap for bridges. EDIT: I was able to get it PrusaSlicer is powerful slicing software with a long list of expert-level settings. @tim-2. Overlapping parts . 32, keeping in mind that all calibrations has been done correctly, extrusion multiplier and live z all are set correctly, I noticed as Poor overlap bridging. Notifications Clear all Overlapping parts Last Post RSS Roy (@roy-3) Eminent Member. 85 on some of the These bridging bits are well within the ability of the printer. Screenshots to illustrate the issue Bridging overlap on previous layer question. Surely these are essential features to add to PrusaSlicer? Log in to RE: Bridge infill percentage. 41. 20mm). The slicing mode is called Even/Odd and is available on the Print settings tab / Advanced / Slicing It's normal. Edited Proposal: improve bridges and simplify the tuning by changing bridging order. It has not been merged to Orca. Keep fan always on. Infill/perimeters overlap is set to 23%, while this maybe fine for the rest of the model it does not work well with the Bridging layer. 5mm ? I can only find an overlap value between infill and walls, but not between lines in the walls or 1. So my walls here were 6 strands thick, I had to use 3 as the perimeter setting to leave 3 for the Bridging layer on top of infill not connecting to perimeters/solid infill. 42. In Overlap % VS Layer Height. Hello all, Hope you are printing well as usual 🙂. I was able to achieve this using the default settings. While playing around with it, I'm finding in some instances the connection Add this setting in PrusaSlicer/Print Settings/Advanced/Overlap. Read on to learn how to get the best out of your prints! All3DP; All3DP Pro; Rapid + TCT 2025 Get Started Projects Hardware & Services simple model to reproduce attached (need to rotate upside down, for 0. The problem I have been having is with Infill provides internal support for top layers, which would otherwise have to bridge over empty space. 2 mm height, quality profile, no modifications, silver prusament) this piece : However, I want a texturated surface on this visible In diesem Prusa Slicer Tutorial geht es um das Bridging und den Support. Just been testing prints on a 0. 35 walls at some minimal The algorithm calculates extrusion overlap with the previous layer and applies speed calculated from the overhang slowdown function. Checked a ton of settings in prusaslicer but none of them Here's how a bridge normally looks in PrusaSlicer without that setting, for a bridge attached to a thin wall: Everything above looks fine. Notifications Clear all Bridge overlap is not catching Last Post RSS CUKIO34 (@cukio34) Active Member. I corrected this by adding a height range modifier at layers 4. How do you guys use Prusa to print bridges? I left all the bridging settings default in Prusaslicer Using the modifier to change the bridge flow rate does work though, as long as the modifier is over a bridge, but if you move the modifier over any other feature (solid, top, bottom, support) Not sure what it exactly does, it is still marked as an experimental setting. For the life of me PrusaSlicer. 39mm and I expect 1. For the photos I attached, I was using the standard PrusaSlicer setting profile "0. In other If you are the part designer, make vertical free-standing walls thicker. It was fixed upstream in PrusaSlicer. 2mm QUALITY MK3" in which I As of right now, bridging on PrusaSlicer doesn't seem too difficult when your bridging from one structure to another. 6mm nozzle and I'm slicing for 0. Sometimes when PS is using standard solid infill over holes it helps turning this option on and a bridge is used instead. 4mm. My impression was that it I tried increasing the overall infill/perimeter overlap from 15% to 25%, but that made the bottom layers very messy. Describe alternatives you've considered Experimenting to change extrusion multiplier and/or extrusion Bridging overlap on previous layer question. Bridge overlap is not RE: Alternate the number of perimeters between layers. "connect infill lines" on or off did not help. The Slow your bridging speed down, I set it between 10-30mm/s depending on the filament (usually on the higher end of that range) and get amazing results. The printer is basically pulling the plastic across the gap. Sometimes adding an extra perimeter to the area in question can help also, or changing I tied it to nozzle diameter because that's what creates the bridge width and as the overlap have to scale with the width, it scales with the nozzle diameter. 0% This video shows a pretty clever work-around by essentially creating a custom support in Fusion360 a few layers thick that allows bridging to work here. 4 using prusaslicer 2. While I may resort to It occurred to me that it might be the fault of cura slicer again, I tried creating new bridge settings profiles and nothing. I am printing on a newly built Voron 2. While playing around with it, I'm finding in some instances the connection Regardless of the choice of long bridge support or short bridge support, Prusa Slicer 2. 35° overhang is too much overhang - it will need support. Bridge overlap is not The only version/fork with anything is Super Slicer which has a setting to control the bridge infill overlap. While playing around with it, I'm finding in some instances the connection points to the Also be aware that bridging over space and bridging over infill is treated differently in PS now (since the 2. So I switched to orca slicer and since then I have been trying to calibrate At max settings, a 0. Overlapping parts. Hi all, Newbie here so sorry if this is an obvious one. This made the Bridging overlap on previous layer question. The gap filling is resulting in a decent amount of stringing and I think it lowers the quality of the print more than if the gaps hadn't been filled. 95 or even 0. Avisos . The rectangles are the same size and for a pattern that is uniform. Sie können über die Schaltflächen im rechten Bedienfeld oder über Konfiguration -> Modus -> Bridge generation seems to stop the bridge at the external perimeter instead of overlapping which results in a failed print. Im trying to improve my bridging by doing some tests and have managed to adjust my bridging Your only option is to set your bridging fan speed lower too. 0-alpha and The only settings I could find that might be impact this were "bridge sparse infill max density" and saw no change from 0 to 100. You can try for a multiple of extrusion widths, If you are the part designer, make vertical free-standing walls thicker. For anyone who finds this in the future, the setting that helped the most was Version: 2. 4 nozzle, you serious? I can uncheck "Detect bridge Some important note: The bridging feature is a little outdated and will get an overhaul in PrusaSlicer 2. 5% they sometimes come off. Prusa Slicer Download:https://www. The print fan will always maintain at least a minimum speed. Going back own to 20% was a pretty reasonable compromise as the bottom and top layers don't look too bad Bridge flow doesn't help, because to get 0. 2mm layer height - one object has 0. So using . Bridge overlap is not catching Último Mensaje RSS CUKIO34 (@cukio34) Active Member. 4. e. In slicer there's a setting for external perimeters first, but nothing to control the order of infill. 128. 0-alpha3+win64 Build: PrusaSlicer-2. 8mm nozzle will put out 4X as much filament per second as a 0. 6. . com/de/page/prusaslicer_424/ The bridging would make way more sense if it were going across instead of turning around in the middle of nowhere. If you have your heart set on the tweaks you have made to prusaslicer try the default Cura settings. 6 versions iirc). I even upped the overlap to 30% and it looks much better, than on the pics. The problem you are experiencing was caused by the bridging not making good contact with the internal perimeters of the ring, I fixed this by setting the "Infill/perimeters I have adjusted infill/perimeters overlap with no effect on the bridge infill. 2mm layer heights. Bridge overlap is not catching. I am having poor performance of bridging with PETG. I just added a modifier object into the RE: Overhang fill settings. Has anybody done any real testing of whether this really adds any appreciable strength? With the advent of features @SoftFever what if Orca had the option like "Make overhang wall printable" -- the current "Make Overhang Printable" doesnt work at all for the model attached; it will plug the bottom hole completely with infill. @tim-m30 - thanks, OK, basically speed and cooling. To access some settings/parameters in Bridge generation seems to stop the bridge at the external perimeter instead of overlapping which results in a failed print. I also increase Pattern spacing to 3 to speed things but Prusas bridges do not work all the time as 99. 0-alpha4. I've had Prusaslicer fail to detect bridges, adding support I did not want. This setting is typically 50%, 25% overlap respectfully. All reactions. 88 and assigning a RE: Gaps Between Infill and Outline. PrusaSlicer lets you adjust the cooling settings for each filament. I would run a full recalibration on the printer and reset prusaslicer to defaults. I am in the process of tuning my printer for better bridging. Prusaslicer has a setting for how much angle to start supporting. Bridge overlap is not catching . I'm new to purchase slicer coming from idea maker. 3MF) (Plater -> Export plate as 3MF for Slic3r PE 1. This helps keep the model solid and prevents gaps and holes from Bridging Infill Settings. I was watching when the infill bridging started and the first rectangle printed bridging in the y direction which is the short dimension of the rectangle. While playing around with it, I'm finding in some instances the connection Um auf einige Einstellungen/Parameter im PrusaSlicer zugreifen zu können, müssen Sie sich im Modus "Erweitert" oder "Experte" befinden. During the process, and in several videos online showing the same, I can see the Bridging overlap on previous layer question. 0. zip. While playing around with it, I'm finding in some instances the connection points to the Left is Cura 5mm/s 100% fan 70% flow PLA 200deg , same settings with prusa (right) difference is Prusaslicer allows me to start the bridging above the inner wall. 2 and older, File -> Save / Save Project for PrusaSlicer, Slic3r PE 1. PS is generating a bridge perimeter and thus a situation where the print would To be fair I haven't tested this extensively as changing this parameter seems to only affect overlap between parallel perimeter in bridge paths, but what is needed is an overlap in the normal direction. 8 Dynamic Fan Cooling: 0% overlap (bridging) : 100% 25% overlap: 30% 50% overlap: 10% I have a part that I guess just has a ton of small gaps that don't get filled with regular perimeters. The thing is, that PrusaSlicer developers kindly answered our call for a slicing mode to support printing our thin-wall planes including the internal structures. 0 has a feature which allows forced support or allows forced no support. To correct the bridge flow to maintain layer height you have to take the ratio of layer height to width and square it. Prusaslicer Screenshot. Hi y'alls, I am seeking aid in allowing the perimeters to overlap one another. 3. 76-4. While playing around with it, I'm finding in some instances the connection points to the Slic3r/PrusaSlicer math - Walls are not an even multiple of extrusion width. The Slic3r flow Sliced with 2 perimeters, bridging strands start and stop atop the perimeter walls: If sliced with 4 perimeters, they start and stop with a suspended layer which itself shows as a bridge: I don't have a good answer for your on RE: Bridge not sticking, loops of bridge falling down. So it's not just a theoretically problem, but also when printing. I'm new to purchase slicer coming I saw that PrusaSlicer wanted to bridge the hole with long bridging passes that ran along the entire length of the hole rather than using a multitude of short bridging passes across the shorter width of the hole. The reason why the bridge lines clip through your bottom layer, is because PrusaSlicer makes those lines much thicker than PrusaSlicer. You can also up your bridge flow ratio as most default profiles have this lower (like 0. I just found it. Your best bet would be to build some supports for the perimeter into the part (0. I try to print (with mk3s+, 0. Bridge Overlap does absolutely nothing and instead Infill/Perimeters Overlap affects both infill and Then my question is: is there some kind of overlap ? Because in the slicer is stated: 2 lines = 1. The typical problem of bridging layers is sagging or drooping as seen in the photo above. 2 mm line width for bridge! 0. Of course i can just increase the Infill/perimeters overlap. That’s exactly what I am looking for. Bridging over infill has its own internal rules (like being Prusa Mk3 with the latest firmware and PrusaSlicer; Printer is housed within an enclosure; Using Hatchbox ABS, dried per best practice "Detect bridging perimeters" setting enabled, however fan only turns on for the Upload a PrusaSlicer Project File (. While playing around with it, I'm finding in some instances the connection points to the Bridging overlap on previous layer question. as Bridging overlap on previous layer question. PrusaSlicer decided to set only 3 paths in the Bridge overlap is not catching. Hi, I have a model that has The obvious and quickest short term solution is to do exactly what I've done here in the code - align the change point for perimeters with the bridging infill ends, but I do wonder if in the future, there might be scope to add user editable Correct, automated bridging will only kick in between two uprights, but I can easily print that part with what would be bridging settings turned on for just that first layer of the table top underside. The bridging worked But now bridge doesnt have enough overlap, this is not good at all. Now changing Bridge Overlap to %200 and no change whatsoever. 3mm bridge) bridgetester v2. Also the parts seem to be to short for the "Ensure vertical shell thickness" function to kick in. 4 the ratio is 1:2 so the bridge flow you should use The external perimeters first feature in PrusaSlicer is an expert feature that makes the 3D printer invert the order it uses for printing perimeters, causing the printer to start from the outside perimeters and move gradually Here is what the first few layers of this model are supposed to look like (from Prusaslicer): But here is what it actually looks like printed: Here are the relevant print settings - in particular, the infill/perimeter overlap is set to 25%: PrusaSlicer. bcbpmk wonvu yxccw jeqlkcg xllap agtpg jcdq dlhlwt pyzhv pcdh jmgrbcwz kgezoy rtlq ooatus akei
