For example to set horizontal shells to 1mm and vertical shells to 1. What does this solve other than porting a issue Cura has with having to warn you when it's not cleanly divisible over to Slic3r?

Also, unless you fix the perimeter width there's a ton of possible combinations and no good heuristic that I can think of offhand to select the correct one. Number of perimeters would be increased until that thickness is achieved, regardless of their divisibility. I'm looking into this. I've added the option in the UI and I'm working on some checks for spiral vase. Skip to content.

In this study we quantify the impact of different layer heights and infill settings on performance, and we try to help users choose the optimal settings by clearly laying out the trade-offs faced by the user. We provide the layer height and infill settings we would pick depending on the application requirements. In the main body of this study, we provide a detailed description of the influence these parameters have on max stress, elongation at break, rigidity Young Modulus and yield stress.

To best sum up the large amount of data we gathered, we present the user with the table of preferred settings we would choose, depending on the application requirements.

Does your print need strength or quality? Are you trying to minimize cost or are you trying to save time? Or is it — as is often the case — a combination of these requirements? These conclusions are based on our interpretation of the trade-offs presented in the following tables:.

The Strength, Speed and Cost tables were extrapolated from the mechanical tests we made [1] :. A much more detailed analysis of the mechanical tests is provided in the rest of the study. Although elongation at break is not part of the requirements presented in the tables above, it could influence the decision on the settings the user ends up choosing.

The other key parameter we looked into was infill pattern. Indeed, decorative patterns such as Moroccan stars and Catfill show poor performance and should only be used if they are exposed and are part of the design. The real debate was between Linear, Diagonal and Hexagonal a. Finally we made a test on the anisotropy of a 3D printed part: this means that 3D printed parts are weaker along the Z-axis than they are along the X and Y-axis.

For each specimen we tested, we measured the following mechanical properties:. The three parameters we studied are:. We aggregated the results and chose to display the tables and graphs we think are most relevant. The characteristics of PLA are well-known when the material is formed by injection molding. The point of this study is to better understand its behavior once it has been 3D-printed with the FDM process.

To give a point of comparison, here are the characteristics of injection molding PLA [4] :. However, it is interesting to note that the evolution is not linear: the strength gained per percentage point of infill also increases. Elongation at break :. The most surprising result of this study probably lies in this test. Elongation at break is remarkably constant around 2. This point deserves a more in-depth analysis to confirm our hypothesis. Consequently, the adjusted curve is mostly constant around 3.

Layer height influences the strength of a printed part when it becomes thin. A printed part at 0. Past 0. Normalizing max stress by weight smoothens the curve a bit, from 4. In theory it should show the same evolution as the absolute numbers, because a constant infill should lead to constant weight, regardless of the layer height.

But in practice — 3D Matter weighs all specimens — the Replicator adds less material on lower layer heights such as 0. The other result is not surprising: it takes longer to print at lower layer heights, so the max stress divided by printing time shows a curve that is increasing linearly.

As shown on the stress-strain curves, the specimens behave the same way on the first part of the curve: The Young modulus remains constant around 2. And yield stress is also fairly stable around 19MPa. The curves differ later, for the max stress as previously seen and for elongation at break: it increases linearly with layer height, from 2.

This is in line with the fact that the material is weaker at lower layer heights, possibly linked to lower accuracy of a thinner deposit. Linear, Diagonal and Hexagonal are all fairly comparable in terms of strength.Isolation Initiative: We want to support you. No contract. No card details required.

Our PLA is significantly stronger than other brands, very easy to print with heated bed not required and long lasting. If however you need something a little harder wearing, and your printer has a heated bed — you might want to go for the ABS.

What temperature should I print my rigid. This varies between materials, so please check the recommendations on the specific product page.

Generally, due to the pure nature and high grade of our raw materials your extruder setting wants to be a little lower than normal. Different printers print rigid. With PLA, no. All other materials including Flex PLA require a heated bed to avoid warping during those first few layers. Not often. If printing direct to glass, your best bet would be to use a good quality glue stick and a apply a thin even layer to your bed before printing.

My 3D printer manufacture recommends only using their filament — can I use rigid. Short answer: Absolutely! You will find rigid. Will your spools fit my printer? Most likely, as our 1KG spools are fairly normally sized. The exact dimensions are: 20cm total diameter, 7. Need an adaptor to fit your spool holder? I want to use rigid. Yes, but please take note to buy the right size for your 3D Pen. If this is causing problems with your pen, simply heat up the filament a little to straighten it out enough to feed it freely into your pen.

Absolutely; we phased out the 3. There is no difference when printing our 2. My filament printed, but then bubbled? This is caused by the filament absorbing too much moisture.

Working on a particularly irksome print and trying to understand how Cura settings interact with the dimensions of my model. Will Cura override my model dimensions or adhere to them? Or, will Cura just go off on a tangent and do something weird?

There are exceptions different topicbut in general the slicer does not change the model but tries to calculate the toolpath in a way that it stays as close as possible to the given mesh geometry. From the perspective of a slicer, a "wall" in the model always consists of two "shells": inner and outer shell.

That's one of the reasons why it is so important that the model has to be "watertight" and must not contain any additional faces inside of solid walls. Depending on the line width and the shell thickness the maximum number of "wall lines per shell" is calculated.

You can always check the generated toolpath in the "Preview" before printing, that's the best opportunity to compare different settings visually although You need to be a member in order to leave a comment. Sign up for a new account in our community.

When I slice a part with 2mm thick walls Slic3r produces the outside shell and inside shell, both with one filament thickness, but no infill. How do I solve the problem? Do I need to design my part with a specific thickness?

slic3r shell thickness

The width of the filament laid down is not related to the free air measurement. It has a height determined by the nozzle height and a width determined by the flow rate versus feed rate. If you look at the g-code you can see the width Slic3r is using. You then need to make the walls twice that or more than 3 times that for infill. Any ideas what I need to change? Thanks, Andy.

Try slightly more as exactly three times is an edge case. Also if the first layer is 0. I have no idea why the first layer should have a thicker outline. If you actually want 2mm walls you could use a lower layer height as that will make the width smaller as well. I normally use 0. Hi, I am having exactly the same problem with slic3r at the moment. If I slice a file in kisslicer it works fine but with slic3r it does not bond the 2 outside perimeters together.

Let say I try to print a 50mm dia ring with 3mm thick walls, it will print the outside perimeters and the inside perimeters just fine, but a minute gap is left in the middle. It looks like the fill is going the same way as the perimeters and not zig zagging to join them. The part falls apart when taken off the table.

And it is the same for any file I do. It may be my settings but I have tweaked slic3r and e steps till the cows come home, so for now I stick to kisslicer. Regards Jan Edited 1 time s. Just did a comparison between slic3r 0. Have looked at a file squere frame xx3 and 5mm high. And the fill runs parallell with the perimeters all the way to the top.Wall thinness problem- what slicer setting to use?

Posted by scarecrow2k6. Hello guys, I have been wondering about this for quite sometime. I use either Cura Repetier Host or Slic3r. What I have notices is that when I try to print single wall object, I get weird artifact in Cura but not in Slic3r with "Detect thin walls" enabled. So I am guessing that in Cura, since all the settings are manual, I might have missed an option that is keeping me away from printing thin walls. For Cura I am using 0. My Nozzle: 0. I have attached a screenshot with half gcode view and half model view.

Edited 1 time s. Reply Quote. Any suggestion guys? It's generally pretty hard to design models for single wall printing. It's generally easier and more flexible if you make the model solid and then let the slicer turn it into a single wall. First, don't try to print walls that match the nozzle diameter. I use 0. Slic3r and Cura have spiral vase modes that will print single line width walls. Son of MegaMax 3D printer: [ www. I should have mentioned this earlier, the purpose of this is to calibrate the printer, eg flowrate etc.

Wall thinness problem- what slicer setting to use?

Yeap that is definitely an alternative way of doing it, never occurred to me though If you're calibrating the extruder, use the calibration guide in the RepRap wiki. Pay attention to the e-steps fine tuning. The reason you have to do it for each spool of filament is because filament diameter varies from one spool to another. Using that average value when you slice or print if you're using volumetric extrusion assures accurate extrusion as long as the extruder has been calibrated.

Whichever method you use, write the extrusion multiplier or average diameter value on the spool for future reference.

Print Settings

Use that value each time you print using that spool. Just to offer a slightly different perspective on extruder calibration, I take a more relaxed approach. Since almost everything I print has solid infill for the first three layers there's plenty of time to eyeball the extrusion on the second and third layer and dial in a one or two percent adjustment if necessary. My printer isn't operating at the level of accuracy that DD's is, so I don't think approximating on extrusion makes much difference to the overall print quality.Toggle navigation.

October in Bug Reports. My Problem is with the Measurements. I got often models, what have to fit at 1mm or better.

Or change it complete, that the wall will be allways adds to to inner side, at the cost from the inner structures from the volume. October First thing would be that you tell us what software you use.

I guess host and one of the supported slicers. These slicers are not from us, so the process is nothing we can do.

2mm Thick Walls

My current favourite is the Slic3r PE and it slices exactly the sizes I want. Error is less then a layer in z and less the 0. For CuraEngine make sure wall thickness is a multiple of extrusion width.

I think that makes it clear how number of perimeter gets rounded. Well, ok, i have to watch that now with this calculations. I got slic3r and slic3r PE installed, just he PE version doesnt run now, any python error there, and i have to fix that first. Slic3r worked so far, but was not to convincing for me. I would like to see if that would make any changes, because i am ok at some strucutures, when its print it as-it-is.

For cura now seems, you allways have to calculate the real printed size, and that can be some disturbing, when you ie. When its more complex, you have to resize it to the right numbers, but for the print then, you would need to add or substract the additional material. What is the error in Pruse Edition? I can slice normally. But you need to configure it first or missing profiles will cause an error.

Sometimes I have seen that old profiles also could crash slic3r. I think limit width is 1. If you have 0. I use Mint There was libwx. Yes, i am aware, that some printer settings just take the settings at the Printer or Firmware. And hmm, just comes in my mind, when i adjust the axis resolutions by printed models, the values are maybe not accurate anymore, when it print a model and i measure it, but what actually differs from the original size from the stl-model because of the additional material from wall thickness.

October edited October Ok, i printed now a few things with slic3r, and seems the measures are equally to the one from the model.
