Linear Advance LA is a technology that predicts the pressure build-up in the extruder when printing at higher speeds. The firmware of the printer uses that prediction to decrease the amount of filament extruded just before stopping and decelerating, which prevents blobs or artifacts at the sharp corners.
What is referred to as ' K-values ' are the parameter determining how much Linear Advance affects the print. With firmware 3. Linear Advance 1. In case you have a G-code with Linear Advance 1.
These values are part of our PrusaSlicer configurations and filament presets. No need to adjust if you are using these. However, if you are using filaments not present or wish to play around with it, we have developed a K-factor calibration print together with the community, to find the perfect K-values for your material and printing temperatures. These are based on the various quality and layer height presets found in PrusaSlicer. It will print a series of lines with different K-values affecting the speed and flow across the accelerated distance.
The examples below show how the lines are affected by their K-value. The first and last 25 mm are printed slow and between the marked locations red squares are mm are printed fast. Look close to the transition from slow to fast and fast to slow. You see the line can be irregular to broken entirely when the value is not optimal, most visible on the top lines red squaresbut present on all except those with the optimal K-factor.
You also see big differences between different materials and how much difference it can make to have this dialed in. Most consistent line achieved with K-value 0.
You can download the K-factor calibration G-code from our print depository or directly from the table below. These are for a 0. Load the correct filament type for the G-code and start the print as any other.
If your usual printing temperatures are different than what provided, feel free to modify the G-Code lines to your needs. The optimal values we found in our testing are listed in the tables below.
These can be implemented into any slicer. Please note that different brands and colors of the same material may require a slightly different K value when printing at extreme speedshowever, our presets should be fine with all of them.
As mentioned, the K-values for all filaments is already implemented into PrusaSlicer's presets. If you need to adjust these settings due to some exotic filament or a specific application, the K-value is set in the custom G-code section in the Filament Settings- tab, NOT under the printer-specific custom G-code. If you are using a different slicer than our PrusaSlicer, you must manually change the settings in the G-code script of your slicer. Simplify3D, Cura, etc.
Keep in mind you need to manually change that for different filament materials. Only PrusaSlicer has a custom G-code for each filament preset and therefore the K value is changed automatically. Set the desired speed and print something large enough for speed to show up. If sharp corners have blobs, increase K value.They can be a bit tricky to use, so we decided to bring you this article that will help you get started with these wonderful materials!
Printing with flexible filaments is yet another way to expand your 3D printer capabilities. Unlike most common materials such as PLA or PET-Gthese filaments offer flexibilitygreat adhesion between the layers and often also elasticity. Printed objects can be not only flexible but extremely resistant to mechanical wear or damage as well. However, there are some downsides, too. Our Original Prusa i3 MK3 printer is designed to print various materials, including flexible filaments.
However, to help you print these materials, we have rebuilt the extruder to MK3S version so it would be even more flex-printing friendly. Although having two different names, TPU is actually a type of TPE material; the main difference between them is mainly in shore hardness.
Plastics called as TPU are usually tougher, their hardness is somewhere around 60AA on the shore hardness scale see below. Shore hardness scale, source: smooth-on. As we have already mentioned, the main advantages of these materials are flexibility, solidity, and elasticity. A great solidity is caused by excellent adhesion between layers. Printed products can withstand a lot of mechanical stress without breaking, which means that flex filaments can be used e.
Among the main disadvantages are things like very slow printing, poor bridging and stringing.Original Prusa i3 MK3 Master Chef UPGRADE
Also, you need to keep in mind that not every model is suitable for printing with flexible filaments and it is necessary to choose carefully what to print.
Generally speaking, printing with softer filaments is more difficult. We have the best experience with TPU filaments with shore hardness 92A and 98A available on our e-shop. So what exactly can be made with flexibles? We have tried to print several simple models that can be used in everyday life or just for fun. We have also asked our fans on Twitter for some inspiration and we got dozens of cool photos — so check out that link to see more! At first, we thought it would be a great idea to print RC model tires.
Therefore they are more suitable for RC plane landing gears rather than for cars. You can modify the tire softness by changing infill parameters and number of perimeters.Not sure how important it is to follow still experimenting with this filamentbut let assume it is. PrusaSlicer only supports setting maximum volumetric speed. However, I'd need to reset it when printing at different layer heights.
Is there any way to tell PrusaSlicer maximum nozzle speed, and let it calculate maximum volumetric speed? I would guess you are right there. As many slicers don't know the max volumetric flow setting it can make sense for filament manufacturers to go with nozzle speeds assuming typical nozzle sizes and layer heights. If you want to convert it to a max volumetric flow I would simply assume a 0. From then onward you can quickly change the setting with a single change of a number.
In the filament settings for each filament profile you can configure a max volumetric rate. There is another volumetric rate in Print Settings too and Slicer will use the lower of the 2 so setting a more realistic rate for a particular filament is respected if you remember to select it.
The volumetric will act as a brake on the print speeds which is why I think some of Prusa's default profiles have very fast infill rates of mms. The max volumetric will slow it down where needed. The infill speed is to fast, if you are pinting a flat big square, then the surface gets bad.
Solution, print slower infill speedor make the extruder hotter, then you get a good surface, this was with pla. And the infill speed i never use again, i made a slower setting, or use the quality setting, here is the infill speed 80, much better.
Thanks all. Said that, it would be nice if "effective speed" would be displayed as appropriate in various parts of the UI.
Setting max print speed for filament
Yes, that where the speeds are adjusted but if you have a filament that requires a different speed than the default print profile, you have to create a custom filament profile AND a print profile. I set the temps in the filament profile and saved that in it's own profile. That makes perfect sense. I would think those speeds would be filament dependent rather than print dependent. I'll math my way to the speeds that work with the volumetric rate but that's a hack.
But there is another issue the mfg needs to suggest: and that is the flow and cure characteristics. Some filaments will have odd surface characteristics if printed too fast; i. So trying to spec all of this in one setting is, well, counter productive.
You need to understand why each setting is suggested. I think you'll have problems with a single filament profile simply because your effective volumetric rate will depend on so many factors under the Print Settings tab. It's the same issue all over again. Raise 3D's ideaMaker slicer has an interesting approach in allowing a filament profile to over-ride any other slicer setting. I wish there was a way to de-link settings from the fixed tabs and let us define free-form profiles that can contain any valid slicer setting.
You can do this from the command line well, it's broken in current PS versions by loading progressively more specific profiles. I see your point bobstro. Thanks for everyone's replies. Once I get through this job in days, I'll be looking for a test piece that I work with for some experimenting. The upcoming PrusaSlicer 2.PETG Polyethylene Terephthalate modified with Glycol is commonly used technical material, popular among 3D printer users for its low price and good printability.
Plus, its high tenacity and flexibility often prevent it from breaking. Parts of our printers are made of PETG! Glycol makes PET less brittle, easier to print, and more transparent for translucent prints. Of course, you can print also with PET filaments without glycol. However, printing with only PET is challenging and does not offer any advantage whatsoever. Although PETG is frequently used in food industry and is considered food-safewe do not recommend it or any other filament for printing dishes or other stuff that comes into direct contact with food.
The main reason is tiny print layer surface grooves that can support numerous bacterial colonies. But if you still want a 3D printed dishes, we suggest applying a special layer that seals the surface food-safe coating and printing with clean steel nozzle. Some of the manufacturers enrich PETG with various additives and sell these materials under different names. The goal is to acquire better visual qualities, surface and layer adhesion etc. To compare supported material properties, see our material table.
PETG is used universally but is especially suitable for mechanical parts for both indoor and outdoor use. We use PETG to print parts for our printers! Plastic bottles are made from this kind of material. Stringing can be moderated with higher retractions and lower nozzle temperature, but we suggest using PrusaSlicer profiles that should work fine. But if you want the model to be as tough as possible, try to turn off the print fan.
Higher filament temperature improves merging between layers which leads to better mechanical resistance. Otherwise, we recommend printing the first few layers with the print fan off to prevent deformation, then with the fan running at half its power. Various manufacturers suggest using various separation or adhesive layers for printing PETG, such as kapton tape, glue stick, etc.
If you want to print truly solid parts, try to increase the number of perimeters instead of adding more infill. Dissolving and smoothing PETG is possible only in a laboratory by skilled lab workers using dangerous chemicals Dichloromethane.Note: This post covers settings in Cura, and primarily mentions the Prusa i3 Mk2. If you check the heatbed with some kind of strait edge make sure you do it when the heatbed is as printing temperature.

Ramp up plastic output thanks to our patented core heating nozzles and fully utilizing the Bondtech feeder already installed in your printer. I increased nozzle temperature to C recommended is C from the manufacturer and I had decent adhesion, but stringing was a problem. I contacted Prusa support and they are sending me a new fan, however I'm not sure that will solve the issue.Prusa Speed Settings Correct extrusion speed depends on the material, e. The perfect retraction speed should be the highest value that minimizes these artifacts without jeopardizing filament flow.
This is a variable speed cooling fan upgrade for the Prusa i3 3D Printer kit. His open-sourced Prusa i3 design is according to 3DHubs the most used 3D printer in the world.

Retraction speed With this setting, you can control how fast the filament is pulled back from the nozzle.
Here are our settings. But I have found at 0. Printing took around 15 hrs combined. You rarely print at your maximum speed anyhow. To say it again: do not compensate a wrong feeder motor speed by tuning the filament diameter, better run the wizard again to properly calibrate the speed of your feeding motor first.
Similarly, you can also change the speed. This time, it has tried once again to surprise its users with an outstanding 3D printer, known as Original Prusa Mini. That setting will override other speed settings to make sure you are respecting volumetric limits. Open the Print Settings tab, select Advanced options.
