PrusaSlicer :

Prusa Research’s high-powered take in the 3D slicer market. Based on Slic3r via Alessandro Ranellucci, in 2016, Prusa branched off with their in-house tale, called Slic3r PE (Prusa Edition) was declared via GitHub.

As Slic3r PE quit further and further from the original software, Prusa formally renamed it in May 2019 to circumvent difficulty. Since then, PrusaSlicer has proceeded to grow and emerge, with updates every several periods.
PrusaSlicer is Prusa printer to help with this easy and open-source application. Thanks to a rich care center, Prusa is now including print biographies for many other businesses. The most advanced variant also comes with higher SLA functionality, electronic variable layer height, and more extra.

In this article, we will be catching a glance at how to begin using this prusaslicer, give you a survey of some of the essential and beneficial traits, both primary and forward, as well as where you can get assistance when you want it and some great options. Let’s start in!

Features at a Glance:

Before actually going into the description, let’s give a fast look at PrusaSlicer’s most important points.

To start, gratitude to the grouping of like settings, the slicer does it very simple to customize and maintain multiple biographies. For instance, a user can change thread profiles without changing printer settings. And with the beyond 110 premade profiles, it is effortless to get begun building your own.

Disturbed you will have to memorize which highly customized forms you did with which design? Don’t be. PrusaSlicer enables you to keep a 3MF file that reserves all things, settings, modifiers, and their parameters.

Another notable singularity:

  • MSLA (pitch) and multi-material preserver

  • Even shifting layer height

  • The system advances using modifier screens

  • Intelligence to “clean” into the infill

  • Capability to service models via Netfabb (only on Windows)

  • 14 languages available

Latest Features in PrusaSlicer:

In case you are previously intimate with PrusaSlicer, here are some amazing and the coolest innovations that came with the advanced 2.2.0 version:

  • SLA hollowing

  • Electronic variable layer height

  • Adaptive elephant’s foot coverage

  • Intelligence to include suspension or custom G-code at a specific height

  • 3MF thumbnails when uploaded to the Prusa website

  • ColorPrint for the MMU

Essential Workflow:

  • If you have nevermore utilized PrusaSlicer earlier, this is the fastest way to get your design sliced and set to print:

  • The central screen begins with a 3D representation of your printer’s build service. Ship your model by agreeing on the add symbol on the prime toolbar. Your chosen model arrives on the build silverware. Managing your design on the build plate is easy. Adjusting the composition is easily done by clicking and moving. Circumrotation and scale engines can be specific with keyboard data or more important with mouse control.

  • Determine your printer, element font, and print settings on the top right.

  • Depending on your design, you can begin supports or attach a border just below the profile choices.

  • Click the preview switch and the application automatically slices your design, with exportation choices in the lower right control.

  • If you need to do more elaborate settings, there’s yet much more to examine, so view on!

The Basics Information:

  • To fully comprehend PrusaSlicer, there are several major features one should become intimate with: the two ways, the three methods, and how to adjust and save your settings forms.

  • Glimpses:

  • Once you achieve the form representative, PrusaSlicer opens to the 3D editor view. This is wherever you will do most of your development work. After importing a model, you have access to the movements, rotation, scale, and cut tools on the left side of the screen. Prusa applies to these devices as “gizmos”.

  • At the head is a list of tools that allow you to copy things and cleave multi-part things, along with other actions. This is also wherever you can obtain the variable-layer-height tool. On the right, you will see the main print-quality collection, the thread (or pitch) settings, and your printer type (or models). You can turn supports and the infill and border settings, and the window just below shows an appearance of implied objects along with any transformers.

  • At any point, you can change to the show view. Doing so will automatically slice your design and give you a preview of the complete print. Here, you can change what’s presented to give you a visual description of items like volumetric flow rates, disclaimers, ColorPrint researches, and more numerous. There is also a helpful window in the lower right that shows appraisals of the cost, the print time, and how much wire will be utilized.


PrusaSlicer has 3 various forms for you to decide between, depending on your level of expertise and the significance of doodle you prefer to do. Settings are color-coded depending on the mode they are “unbarred” with:

  • Simple forms, shown with the color green, presents you with essential buttons to get you begun.

  • Advanced form, shaded yellow, permits you to modify some more complicated settings.

  • Expert form tinted red opens all settings and is designed for the most skilled users.


Settings are collected under three collections, individual of which has its screen: Print Settings, Filament Settings, and Printer Settings. Per set is reached below its tab, has its profile, and assembles special settings into divisions (e.g. “Support material”, “Speed”, and so on under Print Settings).

Whichever model you prefer, all of the settings reside color-coded to imply their corresponding complexity. Additionally, if you hang over a setting, an analysis of the purpose will seem, so there is normally no need to explore within the online manual.

Once you modify a default setting, the outline will adjust to “modified”, and you can protect the profile to use the related settings repeatedly. You can ever return to the default setting by agreeing on the backward arrow next to the setting.

Having completed all this work to set up a copy, wouldn’t it be convenient if you could protect it all? Well, you can! Simply preserve the design as 3MF data. It’ll include all of the profiles, images, and settings just as they are.

Particular Settings:

Now that we know the basics and have seen remarkable of the important points PrusaSlicer is filled with, it’s a chance to understand a few more profound into all the settings we can work with.

Printing Settings:

special concern is the accompanying:

  • Layers and boundaries: This grouping covers the essential settings behind artistic aspects and quality.

  • Infill: This compilation has everything to do with infill.

  • Lining matter: Aside from support settings, here is where you can add afloat.

  • Rush: A likely strong amount of speed settings.

Filament Settings

On this cover, you can change settings that depend on the thread in practice. The usual obvious is the extruder and bottom temperatures, but you also have a choice to weak fan and forward settings.

Printer Settings

If you are just beginning an explanation, there is not a complete lot you’ll require to adjust here. Yet, as you grow, you may want to view the following two perspectives:

  • Retraction length: Nourishes with several print position effects

  • Lift Z: Assists with moving and stringing quandaries
    The printer settings cover is also where you can enter a system G-code.

Advanced Specialties

PrusaSlicer has some top-notch capabilities past the same old cutting settings. This is which you may get very technical together along with your cutting if that is your thing.

MESHES One of the maximum affecting gear PrusaSlicer has is the cap potential to apply modifier meshes. These are shapes created inside the utility that is not published however affect settings for published parts. These modifiers do such things as block or implement supports, regulate layer heights, alternate infill styles or densities, and set unique numbers of perimeters.

LAYERS Variable layer heights can lessen print instances without sacrificing print quality. Previously, layers ought to simplest be manually adjusted, however now you may pick out automated alternatives that examine the version and observe the excellent layer top settings. The device works via way of means of converting the layer top primarily based totally on the form of the version. Another layer-associated function is adaptive elephant foot compensation. Elephant’s foot is that bulge you every so often get in the first layer. With this selection activated, you may regulate how a good deal it shrinks the primary layer to make amends for something impact you will be experiencing.

G-CODE Inserting a pause or custom G-code at a sure top is a completely beneficial function. Pausing at a selected layer lets the person, for example, insert a magnet right into a hollow or change filament colors.

SLA function:

SLA function Since Prusa has its polymer printer, PrusaSlicer has some SLA functions. Choosing Prusa SL1 as the printer will switch the interface to SLA mode, allowing you to use several new tools such as slots and SLA holders. A useful tool for orientation is the “Optimize Alignment” option, which can be found when you right-click the model and open the context menu. This will analyze the model to get the best direction for SLA printing. Holes Using the new punch tool, you can change the wall thickness and add drainage holes of variable width. When you don’t need a solid model, it can save you expensive resin. Support using this feature, you can create automatic and manual support. Although the SLA function is only available for Prusa SL1 printers, it is possible to export the supported models as STL files and then import them into other SLA cutters.

History of Prusa Slicer:

Slic3r’s mission began in 2011 on the RepRap network, to depict the evolving 3D printing era under the control of the open-source cutter Alessandro Ranellucciana. Slic3r develops rapidly with customers. When Josef Prusa started looking for great cutting software. The original Prusa printer chose Slic3, which has become (and still is) a very effective open source program. However, with the development of Prusa Research (very very very fast), we must be more flexible in cutting software development. We must make changes to the program, and these changes need to be completed as soon as possible. We must also download other features. This makes cooperation with the unique and indifferent Slic3r team unsustainable. Most importantly, we decided to share the Slic3r single-player mission. Prusa Edition Slic3r was released in November 2016. A dedicated team composed of permanent Slic3r PE developers was created, and new features were quickly introduced. When these changes reached their ■■■■■■ in May 2019, we released a new version and redesigned the main user interface under new challenges: Why are the PrusaSlicer challenges First of all, the old appeal is confusing. Even in our data, we usually do not include the “PE” suffix, and we can use Slic3r and Slic3r PE interchangeably on the Internet. I downloaded Slic3r accidentally, wondering why it looks specific in the screenshots of the 3D printing manual, and why it is no longer configured for your Prusa printer. Roughly speaking, the only Slic3r: After each update, the Slic3r PE becomes an additional port and is further removed from its unique code. We rewrote all the Perl source code in C++, especially the second zero update. There were so many changes that seemed to make the call clearer.

Main Improvements in Prusa Slicer:

The central changes did in this great release:

  • The Infill

  • The Surface

  • The Supports

  • The User interface

  • The Infill Cubic-

This infill kind is unique as it makes items robust in all directions. Compared to vintage fashion infills had been you may compress the item in the horizontal plane, further like an accordion. Only pinnacle and backside strong infill avoided this, but Cubic infill makes the item inflexible through itself! This is best for mechanical parts, much less print time and the fabric is wanted to get equal if now no longer higher structural results.

Summary: There are many extra modifications below the hood, consisting of a whole rewrite of infill into C++11, that is high-quality for destiny rushing matters up.

The Surface-

A new magical choice seems withinside the brand new Prusa Edition Slicer, and this is “Ensure wall thickness”. It solves one in every of the most important problems of authentic Slicer, and this is having holes among the sides on a slanted surface. This became standard while printing busts and different natural searching models. Object revealed splendid however on the pinnacle of the top there had been few unsightly holes, what a bummer :-/ Well, now no longer anymore. Slicer now makes certain it lays down the wanted help for perimeters in the upcoming layer as visible in pink in the photograph below.

summary: The outcomes are fantastic as you could see at the pumpkins below. On the left is the authentic Slicer and Prusa Edition is at the proper. It is simply night time and day difference.

The support-

Supports are usually a query in terms of FDM printing. Slic3r wasn’t high-quality to mention at least. But with our tweaks we are becoming there, proper now I could individually say we’re at more or less 90% of the Simplify3D achievement charge, and paintings splendid! They are nonetheless a bit slow, as they’re nonetheless now no longer ported to C++ however they’re the principle precedence now.
The User Interface-

Added slider n g-code preview window permits you to look most effective phase of the sliced item without the distracting details. There is even a choice to reveal the most effective 1 layer which locks each slider collectively and displaying the most effective decided-on layer.

Summary: Another splendid addition is a “Slice now” button, which generates the version without saving it. Background processing may grow to become off any further because it makes the Slic3r consumer interface very laggy.

The Best Media Settings for 3D Printing.

The support of 3D printing is essential for printing protrusions. However, it is difficult to find the correct settings so that the tool can be moved easily and the elements will not be deformed in.

Step 1. Cura support settings For information about good help settings, I use Cura2. I tried Cura 15 (it is older than Cura 2), but there are far fewer customization options. I also tried Meshmixe and its helper tree branches are impressive, but they caused me some problems because these tools no longer fit their intended location. When I need to quit Cura 2 in general and why I should use it: it is very free, human friendly, and has many basic settings that allow some printing options. Yellow is a photo of the appearance of the placement surface. You can load other settings under “Print Settings: Advanced”. Just drag the mouse to the gray tab (such as quality), click on the displayed widget, and then enable or disable the desired option. There are many settings, and it may take a few days to check the integrity. Therefore, I focus on the most important parameters for me: temperature, home aids, support + interface, interface thickness, five, distance to the element.

Step 2: Link From this step to step 6, I actually posted many comparable parts and only converted one Note that it has been enlarged a lot, so the tool can be placed anywhere under the part (actually, the part I designed has a little “foot” on one side, so the part you want to publish is displayed facing down). For better scoring of all articles, this is a referral link. This is a small square block (30mm x 20mm x 2mm). In the image below, you can see the top of the part, while the following steps show the bottom in contact with the tool. Its release has the following parameters: 180°C (at higher temperatures up to 210°C, no visible changes at the top) speed 50 mm/sec resolution 0.1 mm (but this does not affect this photo (this is the path The highest part) (the diameter of the hot end is 0.4mm).

Step 3: Change the (basic support) First, I checked the “Enable Help” box in Cura on the “Support” tab and tried to print a part with a specific temperature. Go to “Activate Support Interface” under the “Support” tab and try again at a special temperature. The effect is surprising: Compared with a simple assistant, the elements of the user interface are much simpler. However, if the temperature is too high (210°C or higher), the additive will stick too much. Deleted from the project, it cannot be deleted.

Step 4: Change the thickness of the interface. Based on the results outlined above, I decided to save the interface and specify its thickness. The idea is to make the interface thin enough so that it can bend when you lift the interface. Here, the consequences are also impressive: Not surprisingly, the thinner the interface, the easier it is to bend, but the thinner the distance, the more it adheres to the component.

**Step 5:**Change the distance to the interface. In the end, the remaining space I took up became a gap for isolating the accessory (or its interface). (If any)) and the article. Again, it’s worth trying-as the distance increases, it becomes easier to postpone help. On the other hand, the surface of the element in contact with the auxiliary piece is stronger and has a better distance.

Step 6: Choose the best setting. For the above reasons, I decided to continue with the quick setting after a few attempts: Temperature: 180°C to 190°C. Please note that if the temperature is too low, the product may be damaged. Since the layers no longer bond well to everyone else, they are very fragile. The interface supports ON. Interface thickness: 0.6 mm. The distance from the auxiliary interface to the component: 0.2 mm.

Step 7: Smurf test What is the Smurf test? I just want to test the above setup with a particularly tricky part, and the small form factor will be perfect. Therefore, I chose a Smurf, placed it face down in Cura 2, and placed it so that you can see if you can easily delay it and if the bottom is light enough, as shown in the: Soft support for the shelf: For the entire shelf, it takes less than 1 minute. Soft enough. What I want to say is that its resolution is 0.2mm (instead of 0.1mm). When she got rid of the aid, her nostrils also ruptured, but since then.

PrusaSlicer vs Cura:

prusa slicers vs cura

What do you assume? My evaluations to date the usage of the Ender three seasoned with the reputable silent board and octoprint.

  • PrusaSlicer is tons quicker, extra light-weight, and additionally quicker to operate (e.g. pause at height). Both have comparable complexity.

  • PrusaSlicer has a much wider default extrusion width and decreases default speeds. With the adjustment of only a few settings (e.g. minimal layer time), the print time is sort of identical.

  • Top surfaces appear a chunk nicer with PrusaSlicer.

  • PrusaSlicer has no choice to clever disguise the seam. That stated I turned into blown far from the quality. In of my prints (a hoop the usage of wooden PLA and an astronaut the usage of obvious ABS) I could not even locate the seam! Nevertheless, I assume it’s miles simply vital to feature this feature.

The best slicers from beginners to professionals:

It was developed on a large Ultimaker 3D printer and used in the company’s customer network. Slicer software is free and open-source. The printer can extract the maximum number of documents with the maximum number of abnormal 3D codecs (including . STL, OBJ, X3D, .3MF) (excluding codecs used for image reports (including BMP, GIF, JPG, and PNG) )). Suitable for beginners and professionals, some of the functions include track display, printing time, and fabric consumption calculation. Experienced customers can use the plugin on their third birthday. 3DPrinterOS 3DPrinterOS is a completely cloud-based platform that integrates cutting applications and various key 3D printing functions, including recovery applications. Therefore, the platform represents the original way of dealing with documents and customers in the company.
