2020 • All rights reserved. June 12, 2020 by CrackedConsole Chuck takes a look at Cura 4.6 Slicer and Horizontal Expansion Improvements in this episode of Filament Friday. It is even more difficult to try to repair a non-manifold object than building it from scratch.

For a detailed STL file repair in Netffab program, read our Guide on How to Export 3D Models in STL Files and Prepare for 3D Printing. This is how the object we talk about throughout the article printed out: Gambody cares about the printing experience of its customers and provides correct and tested printing settings for all 3D models that are displayed on the marketplace’s website. If you’re not attentive and careful when modeling, it can ruin all your work and you will be forced to waste a lot of time correcting or you might see yourself in the position to start over. He test the new Horizontal Expansion for holes only and discovers a few things. For an object to be watertight, there should be no spaces or gaps between its intersecting or overlapping inner and outer faces. The outside should be 30mm wide and the inside 15mm.

The feature that you need to enter a correct value for is Horizontal expansion. In Slic3r, you can find this as Print Settings/Advanced/XY Size Compensation. Because the extruded molten plastic gets squashed by the nozzle and also flows outward toward the sides, everything you print is fattened, creating overall oversized prints and undersized holes. Do you use 3D printing to make functional parts?

Do your printed parts have slight dimensional errors, such as undersized holes? However, avoid entering a bigger value as it results in a thicker layer, which is not recommended. Or, suppose you have a model with elements that overlap one another. After having entered the 0.04mm value for Horizontal expansion feature, the object is seen in CURA 15.06 program as watertight and manifold, which is the result we are looking for. Take the repaired file and upload it into the slicing program you use. When we import the file in CURA 15.06, it looks as follows: CURA chops the object in thousands of layers, enabling you to see every single layer the object consists of. For a watertight model, the value must be 0.04mm. Drag the repaired STL file in the program’s window.

It can also be set by default. When you login first time using a Social Login button, we collect your account public profile information shared by Social Login provider, based on your privacy settings. Use a caliper to measure the size of the outside and the hole. We use CURA 15.06 slicer for Ultimaker. Check the Printing Details tab on every 3D model’s page before firing up your 3D printer. This blog was created to provide you with useful 3D printing articles and the latest news of the world of 3D technology and machines.

This tool identifies and repair most common errors in your file. Compensating by slightly changing the values in CAD: this is cumbersome if you use different printers or have collaborators, and problematic if you work with assemblies in CAD. In this post we will talk about the things you can do to prevent your model from printing with gaps or holes.

First, I would recommend against these methods, if you currently use them: In Cura, the Horizontal Expansion setting allows you to set a compensation value for the aforementioned print “fatness”.

We managed to build a manifold or watertight object, which will generate accurate print result.

Different software has this feature called differently.

Copyright © Gambody, 3D Printing Blog. Fortunately, there are ways to fix this flaw. See the 3D printed Fallout 4 T-60 Power Armor model below.

Use a caliper to measure the size of the outside and the hole. Check the model before sending it to print, make sure it is watertight and check printing details or settings that are recommended for a certain 3D model. The entire model (figurine plus support)has been modeled using primitive elements. After you’ve checked and repaired the errors in your STL files, it is time to proceed with the printing.

If you have an Ultimaker 3D printer, than the above CURA 15.06 settings will definitely help to to print files hassle-free.

There is no gap or space between the elements and the overlapping faces of the composed element.

Here’s the easiest and most elegant fix, using nothing but your slicer and a caliper.

After having entered the 0.04mm value for Horizontal expansion feature, the object is seen in CURA 15.06 program as watertight and manifold, which is the result we are looking for. Published with WordPress. Even though you are certain that the model is watertight and it lacks errors, we advise you to check it in Netfabb. Compare your measurement to the intended values. Different software has this feature called differently. Changing the size in the slicer: FDM 3D printers generally have undersized ID and oversized OD, so enlarging or shrinking the size is bound to reduce one problem while worsening the other. 2. that’s nice, i tought only my printer had this problem and i always designed it oversized for a perfect print, thx, cheers from brasil.

A “watertight” object means that if you fill the object with water, it will have no leaks. If the feature is not set by default, take several minutes to set up the software correctly. Don’t let the printing of your 3D model fail, without taking actions first. For an STL file to be printable, it must be uploaded in a slicing program that generates the G-code for the printer to be able to read the correct geometry of the object. This is the X-ray view mode of the object, where you can clearly see how the elements “merge” together. Onyx WordPress Theme by EckoThemes.

The non-manifold problem occurs most frequently in 3D models with complex geometry.

To be able to see the layer pattern of the model, rip cut the object.

For this purpose, we’ve colored them differently, to make it easier for you to distinguish between different elements. Read our easy-to-follow in-depth Cura tutorial to explore the hidden features and settings of the Cura slicer software - that’s where the fun really starts! We also get your email address to automatically create an account for you in our website. This is how most complex objects for 3D printing are modeled.

When we do so with our 3D object, we see that the object is seen as being built from several separate parts. This issue can be avoided if correct settings for CURA 15.06 software are provided. If you don’t have a caliper, you can still estimate your tolerance error using a test like this. Creating a watertight or manifold model is not simple. Non-watertight or non-manifold mesh occurs when the dots or edges have not been connected to create a solid object. Overlapping geometry is your worst nightmare. See how you can distinguish every element of the object. Negative values make your prints “skinnier”. If your print was too fat (it usually is), that’s what you want. Like the one in the picture below. Firstly, you should know that in order to print a 3D model as a single object, the mesh must be completely manifold or “watertight”. Print this test I made. In the picture below you can see all the elements an object is made of. In Cura, the Horizontal Expansion setting allows you to set a compensation value for the aforementioned print “fatness”. In Slic3r, you can find this as Print Settings/Advanced/XY Size Compensation. It can also be set by default. Therefore, we will illustrate how this process works with this particular program. A 3D printing website where users can buy and sell 3D printer files. This technique confuses the slicing program that generates the G-code and the model gets printed with errors. Nothing can be more frustrating than 3D model printing with gaps and falling apart.

Average the difference between X and Y directions and between outer and inner. If printing details are not provided, check and repair STL files of the model before starting printing it. Sometimes, a single setting feature can cause you a headache. He also looks at a few other features new in Cura 4.6. If the outside is oversized and the inside is undersized, use a negative sign and type it into the “Horizontal Expansion” box in Cura. This is a complex 3D model of Fallout 4 Power Armor, consisting of thousands of polygons. If you’re squashing your initial layer, make sure you first use a reasonable Initial Layer Horizontal Expansion to eliminate elephant feet.

They divide the object in several elements, with no joining points among them, which will print separately and fall apart, if the problem is not fixed. It is essential to take care of this if you use your FDM 3D printer to make precise or functional parts.
