3d printing first layer rough I was over-extruding slightly (even though I calibrated my extruder). Still, filament seems to vary. Apr 6, 2022 · I own a spool of PETG and I have been having major print quality issues: layer offsets, chunks of 3D print strewn across the buildplate and other things. Gaps between lines: Caused by nozzle too far from bed. 75 filament, my sprite extruder was bang on for e-steps, exactly as Creality recommended. Next thing I'm going to try is turning off the cooling fan for the first 3-4 layers and see if that helps. Printing at 0. Once you get the extrusion multiplier set, you can go back to printing the first layer object and further dial in the first layer. Second, refine flow. Configuration: Printer: Prusa Mini Deviations from standard: None, original nozzle, original PINDA sensor, only thing that has ever been changed is PTFE tube Z offset mostly just affects the first layer but it can affect the first few layers if it's bad enough. One thing I noticed was if I manually forced the cooling fan on for the first layer, I'd get a rough texture as well. In all cases (except the sample print) the first layer is extremely rough. Also, you should turn off cooling when printing the first layer to allow it to set correctly. When I print with PLA, I get a perfect first layer. For 3D printing first layer rough, we provide some effective solutions It will tend to build up in the first couple of layers and make them rough. The general process is: Set flow rate to 100% Print first layer tests and adjust z height until you get a good/smooth first layer. The sample print included with the software printed perfectly. Aug 19, 2024 · Why is my first layer so rough 3D printing? A rough, uneven first layer can be the result of several different issues. Nov 5, 2019 · Michael Dwamena is the founder of 3D Printerly, a platform dedicated to simplifying 3D printing for hobbyists and professionals alike. If the first few layers appear to shift, it is obvious that subsequent prints cannot be completed, and the printer needs to be adjusted or sliced to be reprinted. To fix rough second layers in 3D printing, follow these solutions for leveling the bed properly, adjusting print temperature, and improving adhesion. The first layer looked great, but in reality it was over-extruded. Redirecting to /blogs/maintenance-guides/3d-printing-first-layer-problems Aug 10, 2022 · How to Fix a Rough Second Layer in 3D Prints. Jan 19, 2023 · The issue of a rough first layer on a 3D printed model essentially refers to plastic uncontrollably spreading over the first layer, as if the printer were smearing the plastic on the first layer rather than placing the print lines carefully. Adjust Z-offset and run calibration test. By leveling the bed properly, you can ensure that the first layer smoothly adheres to the bed, leading to better adhesion overall. 6 as my slicer. In slicer there is a setting for flow for just the first layer, so the levers you can adjust are the z_offset, flow and width. Nov 1, 2020 · Hello Friends! I’m brand new to 3D printing and received my A350 about a week ago. Once thoroughly cleaned and dried, try again. We're only talking about small fractions of a millimeter. It's weird. Mar 6, 2025 · How to Fix Rough Second Layers in 3D Printing. First Layer Issues. With the ABS/UpBox, I printed a raft and the model detached from the raft very cleanly leaving a smooth surface. Owns over 20 3D printers (filament and resin) and has plenty experience 3D printing. Flow rate for one filament might be 0. A REALLY messy first layer can mess up a few layers above it, but it's still a first layer problem. This causing the nozzle to drag as it printed the second layer. Printing Temperature May 2, 2024 · This is a normal consequence of 3D printing. As it’s printing the first layer watch for those strings and slowly adjust it down until you’re printing perfectly with no strings. First, refine your Z offset for the first layer. Printing experience: One year with the mini and the old flashforge woody with double extruder. Still no. 9, while another is 1.

Michael has authored over 900 articles, helping millions navigate the exciting world of 3D printing. In Bambu Studio create a new project; Right-click the plate and add a part Mar 14, 2023 · The first layer lays the foundation of the 3D printed model and is critical to the success of the print. Over-extrusion Sep 8, 2020 · Printing at a high speed can cause the problem of rough edges and corners just because the new heated filament layer on the previous layer will be extruded in very little time. I also suggest checking the extrusion widtd by measuring a single wall calibration box. I usually print PETG around 230 as a reference for you. A rough second layer can occur despite or even because of a good first layer. Poor adhesion: Caused by low bed temperature, dirty bed, or incorrect adhesive. 24, 50mm/s layers, 0. Jan 2, 2025 · Now, go to the 3D printer first layer problems you're facing now and get the fixes below. You might need to adjust z_offset lower or higher as you dial in the extrusion multiplier. Oct 25, 2023 · Rough first layer: Caused by nozzle too close to bed. I use Ultimaker Cura 3. I don't know how to fix this. I haven't had this issue at all with any of my other PETG filament colors. Mar 13, 2023 · We focus on the print quality of the first layer, first making sure that the first layer is properly attached to the print bed. Members Online Guy on YouTube with 4k subscribers is working on a cheap, universal, mostly 3d-printable pellet extruder, and appears to have solved most of the problems associated Jan 17, 2024 · 1. Nozzle is too close on the corner with the strings popping up. Everything after the first layer is controlled by flow rate. Let’s look at some of the causes of this issue. My bed is level (both before and after installing BLTouch), and bed adhesion has never been a problem. I'm fairly confident this was due to filament inconsistencies. There are a couple of things that can go wrong when printing your first layer. $\endgroup$ – Pᴀᴜʟsᴛᴇʀ2 Sep 11, 2020 · Since you are printing more layers, the extruded plastic has more of a foundation to build up from, which is your 3D printer creating smaller steps to create that overhang in the first place. This is how I dial my level in now and it works great. I'm also not squishing the filament, I can clearly see small gaps between some of the lines of the first layer. If there is a problem with the printing of first layer, the model may not attach properly to the print bed, displacement may occur, or the bottom of 3D print not smooth. You want to avoid having to use supports in the first place, but if you do have to implement them, you want to make them as efficient as possible.

I had a bit of a meltdown with PETG getting all burnt up inside the print head sock, so I cleaned it with a wire brush in maintenance mode and got the print head out. Since then I have tried several different prints, some I designed in Fusion 360 and some I downloaded from the Internet. 3, 20mm/s first layer, between 200-210 degrees. As the foundation to your whole print, it is essential in providing proper adhesion to the build plate. Then move on to printing some test cubes. I've tried tweaking with the bed leveling and giving a little more gap on the first layer, but that doesn't seem to change anything either. I replaced it with a new 0. The only way to know for sure is to print a test piece, measu Nov 21, 2021 · RE: Rough first layer. The previous layer will not have the required time to cool down properly because the new heated filament will be extruded on it. Many common 3D printing problems stem from a poor first layer. I’m using the PLA that came with the kit and using . I also calibrated the extrusion multiplier and it's spot on now. I traced these effects to a single culprit: rough layers. The first layer of your print is probably the most important layer. I would recommend printing a single layer test before to verify it’s completely clean. When printing the first layer of a print, it’s essential to print it hotter than the rest of the layers for the best adhesion. If you don’t have a file to use, you can easily make one as follows. Level the bed and increase first layer height and width. The rough surface leads to poor adhesion between layers and less fine details, ruining your Jan 28, 2022 · Best Cura First Layer Temperature. Improper nozzle distance, where the gap between the nozzle and print bed is not optimal, can prevent the filament from being laid down smoothly. If they doesn't work I'm going to try drying out my filament in the oven just in case. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing and development of 3D printed parts and devices.
