I’m reaching out to seek advice on improving print quality on my Snapmaker 2.0 (A350). I’ve been experimenting with various settings for a few weeks now, and while I’ve made some progress, there are still areas where I can’t seem to achieve the results I’m aiming for.
Here are some details about my setup and the challenges I’m facing:
Filament: I’m using PLA with a 1.75mm diameter from a reputable brand.
Nozzle Temperature: Currently set to 200°C.
Bed Temperature: Set to 60°C.
Layer Height: Using a standard 0.2mm.
Challenges:
I’m noticing stringing between certain parts of my prints, especially on more intricate models.
The first layer adhesion is inconsistent, even though I’ve leveled the bed multiple times using both manual and auto-leveling.
Fine details on smaller parts of the print appear slightly melted or blurred, which affects the overall finish.
I’ve gone through the Snapmaker documentation and some online guides, but I’m wondering if there are specific tips or custom profiles that the community has found useful. For example, are there particular adjustments I should consider in the Luban slicer settings (or other slicers) to tackle these issues?
Additionally, I’ve seen mentions of upgrading certain components, such as the hotend or using different bed adhesives—are these worth exploring?
Any insights, suggestions, or shared experiences would be greatly appreciated. I’m eager to learn from this fantastic community and take my 3D printing skills to the next level!
Welcome to the forum and congrats for mastering 3D printing to this point!
I’ll try to give a few answers to your problems, which however will be a bit generic. For more specific help I’d recommend that you post individual cases of your problems, ideally with photos. The community here is eager to help as good as they can!
Stringing
In general many parameters can cause or mitigate stringing. Here are those I’m aware of:
Humid filament: it seems the more moisture was accumulated by filament, the more it tends to create strings. Solution: Dry your filament - in the oven, a food dehydrator or in special devices (filament dryers) for that.
Retraction settings: Filament retraction is a slicer setting which lets the print head pull back the filament a bit before travelling between two print locations. Playing with these settings can help getting better results.
temperature, colling and print speed - all these parameters influence stringing. To get the best settings, there a test objects you can print to tune in your filament, e.g. a temperature tower.
First layer adhesion
Unfortunately a not uncommon problem with the Sanpmaker 2.0 - the print bed often is bumpy. Some users are affected more, some less. Here’s a bit of additional information: Bed Leveling - Revisited & Detailed
But before you start that journey, perhaps check the “obvious”:
Clean bed: The print sheet needs to be clean for good adhesion. Consider using warm water & dish soap to give your print sheet a jolly good cleaning ever once in a while. And/or use Isopropanol.
Fine details
This is the most difficult to give general advice to - what are “fine details” to you? Especially here specific cases and photos would be helpful. I once printed a very detailed miniature - perhaps the settings there help you? Tabletop miniature with 0.2 mm nozzle and PVA support (Dual Extruder)
I general, for good details do not go too fast, make sure print cooling is on, and potentially avoid overheating of protruding parts: Overheating | Simplify3D Software
And of course a layer height of 0.2 mm limits your details. For very detailed prints you may want to go for 0.1 mm, or, as some slicers offer, use adaptive layer heights.
Bed adhesives: I personally used painter’s tape, glue stick and hair spray with success, but only found them useful on my previous printer that had a glass bed. On the Snapmaker print sheet IMHO PLA has a very good adhesion - if you have Z-.offset and bed levelling right.
