A slicer cuts a 3D model into layers and writes the G-code that a printer follows, so it shapes print quality as much as the machine does.
Most options cost nothing, many descend from one another, and a few are tied to a printer maker. This guide ranks twelve on setup effort, real price, exit, independence and the printers each one serves.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
In short
What 3D printing slicer software does
3D printing slicer software converts a digital model into printer instructions, setting layers, infill, supports, speeds and temperatures, then exports G-code or sends it to a printer for filament or resin machines.
We ranked the 12 3D printing slicer tools on setup effort first, then total cost, then data export, then exit, then fit for the buyer. One rule sits on top of those tests: places 1 to 3 go to challengers, vendors outside the best-known brands in a category, wherever the category has them; the established names follow from place 4 in their ranked order. Why those five, and why there is no score out of ten, is on the how we work page.
Community slicer with a built-in calibration suite for FDM printers
Ranked #1 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierPublished pricingElsewhere
OrcaSlicer suits people who tune printers often. Its calibration lab produces flow, pressure advance, retraction and tolerance tests without hunting for test files, and adaptive bed mesh probes only the area a print needs.
The AGPL-3.0 code, absent account requirement and AppImage, Flatpak and Windows builds make rollout simple. The cost is self-reliance: issues go to GitHub, and nobody is contractually obliged to answer.
What stands out
Calibration tests
Klipper and OctoPrint
Windows, macOS, Linux
Where it costs you
No named company stands behind it, so an organisation that needs a support contract has no one to sign with.
Resin and SLA printers are out of scope because it only slices for FDM machines.
Right for
Owners of Klipper or Bambu-style printers who want to calibrate and tune on their own.
Wrong for
Teams that need a vendor contract and a helpdesk.

Open source slicer from Prague, paid for by printer and filament sales
Ranked #2 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierOpen sourcePublished pricingEurope
The vendor says all slicing runs on the local machine, which fits air-gapped workshops, and the whole program is free and funded by Prusa's hardware and filament sales.
Organic supports reduce contact points, and Printables models import straight onto the plate. Because the same company sells printers, roadmap priority follows its own hardware, and other brands depend on community profiles.
What stands out
Organic supports
Local-only slicing
Printables import
Where it costs you
The version offered on the download page at the time of checking was an alpha, so stable users must pick an older release deliberately.
Default profiles are tuned first for Prusa machines, so other brands may need hand adjustment.
Right for
Prusa owners and anyone needing slicing that never leaves the computer.
Wrong for
People wanting resin-first workflows or cloud slicing.

Paid desktop slicer sold as a single licence per user
Ranked #3 of 12 in Best 3D Printing Slicer Software in 2026.
Published pricingNorth America
Simplify3D charges a single price per user, offers volume discounts on request and gives a two-week money-back window, which makes budgeting easy. The vendor says it tests on a large in-house collection of printers and ships tuned profiles.
Version 5.1 added ironing, monotonic infill and wider WiFi support. Buyers should compare that against free options, since the licence pays mostly for support and tested profiles.
What stands out
Paid licence
Printer profiles
Version 5.1
Where it costs you
The licence is paid, while several open source slicers now match much of its feature list.
Upgrading from Version 4 is a separate purchase, so earlier buyers do not get Version 5 automatically.
Right for
Shops that want one paid licence with vendor support and profiles.
Wrong for
Hobbyists who only need basic slicing at no cost.

Slicer for resin and filament printers with a free Lite edition
Ranked #4 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierPublished pricingEurope
Lychee handles resin and filament jobs in one program, with three tiers: a free Lite edition, Plus at a monthly or yearly price and Library, which adds over 3,600 pre-supported models.
Lite includes a thirty-day Plus trial and allows three activations. The model catalogue saves hours of support placement, yet the licence terms limit commercial use, and the company legal entity is not named on the site.
What stands out
Resin and FDM
Subscription
Pre-supported models
Where it costs you
The free Lite edition shows ads on export and limits Multi-Plate to a partial feature set.
Library models are for personal use, because commercial use needs approval from each creator.
Right for
Resin printer owners who also want pre-supported models in one subscription.
Wrong for
Users who dislike subscriptions or want an open source licence.
FranceFree Lite edition; Plus and Library plans published monthly or yearly
Long-running open source slicer with 400 settings and a plugin store
Ranked #5 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierOpen sourcePublished pricingEurope
Cura gives beginners recommended profiles and experts a Custom mode with more than 400 settings. Marketplace plugins and material profiles cut manual setup for third-party filaments.
An Enterprise edition can be rolled out through system distribution tools, gets two releases a year and publishes a summary of its vulnerability scan. For plain use, the free LGPL edition is enough, and the company sells printers beside it.
What stands out
400+ settings
Marketplace plugins
Enterprise edition
Where it costs you
Newest motion-planning features arrive first on UltiMaker's own printers, not on third-party machines.
Cura is a general slicer, so calibration helpers found in its forks must come from plugins.
Right for
Schools and offices with mixed printers wanting a familiar, stable slicer.
Wrong for
Tuners who want calibration wizards built into the slicer.

Slicer forked from PrusaSlicer, published by Bambu Lab on GitHub
Ranked #6 of 12 in Best 3D Printing Slicer Software in 2026.
Open sourcePricing on requestElsewhere
Bambu Studio is a PrusaSlicer fork released under AGPL-3.0, with builds for Windows, macOS and Linux including AppImage and Flathub packages. Slicing works without the proprietary plugin, and an SD card can carry the file to the printer.
The same README credits Slic3r and PrusaSlicer, so the lineage is documented. What remains unverified is company location and support terms, since the vendor pages were unavailable to us.
What stands out
PrusaSlicer fork
Windows, macOS, Linux
Optional network plugin
Where it costs you
Printing through the cloud needs a separate networking plugin built on non-free libraries.
Its vendor site rejected our checks, so pricing, support and hardware claims beyond GitHub could not be confirmed.
Right for
Owners of Bambu Lab machines who accept the vendor's plugin for cloud printing.
Wrong for
Buyers who need verifiable vendor facts or a support contract.

Single-maintainer PrusaSlicer fork exposing extra calibration and tuning options
Ranked #7 of 12 in Best 3D Printing Slicer Software in 2026.
Open sourcePricing on requestElsewhere
SuperSlicer is a PrusaSlicer fork under AGPL-3.0 whose README speaks in the first person of its author, which marks it as an individual's project.
It converts STL, OBJ and AMF files into G-code for filament printers, or PNG layers for mSLA machines, on Windows, Linux and macOS. It suits tinkerers who want more knobs, but the lack of any company makes it hard to justify in a managed setting.
What stands out
PrusaSlicer fork
Individual maintainer
FFF and mSLA
Where it costs you
A single maintainer owns the repository, so continuity depends on one person.
There is no vendor, helpdesk or support agreement behind it.
Right for
Users who want extra tuning options in a PrusaSlicer-style interface.
Wrong for
Organisations that need continuity guarantees or procurement paperwork.

Raise3D desktop slicer with STEP import and per-layer parameter changes
Ranked #8 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierPublished pricingElsewhere
ideaMaker lets you change parameters for a group, a layer or a volume, generate textures from greyscale images and import third-party filament profiles through the ideaMaker Library.
It reads STEP and IGES directly, which most free slicers do not mention, and exports G-code or DLPCODE. The listed Windows, macOS and Ubuntu requirements are modest, but the page leaves out any licence statement.
What stands out
STEP and IGES input
Adaptive layers
DLP templates
Where it costs you
The page names no price, licence or paid edition, so terms for commercial use are unclear.
Its DLP templates target Raise3D's own resin machines.
Right for
Raise3D printer operators who want STEP import and layer-level parameter edits.

Ranked #9 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierOpen sourcePublished pricingNorth America
MatterControl pairs a slicer with MatterCAD design tools and Cloud Sync, and the page lists it at zero cost. It supports printers that take G-code or X3G and allows live changes to Z-offset, speed and extrusion while printing.
MatterHackers Inc. sells printers and filament too, which funds the free software. The licence is not named, so check the repository before redistributing.
What stands out

Craftbot slicer with Smart, Easy and Expert modes and a free tier
Ranked #10 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierPublished pricingElsewhere
Craftware offers a free Standard tier with complete slicing and three modes named Smart, Easy and Expert. Premium plans add productivity functions for up to three devices, and Premium Enterprise covers up to ten devices for companies with revenue above a stated threshold.
Multilayer contraction and mixed-nozzle heterogeneous prints appeal to IDEX owners. The stale release dates and missing company details count against it.
What stands out
Free Standard tier
IDEX support
Premium subscription
Where it costs you
The latest Linux and macOS builds listed date from February 2023.
Premium prices are quoted in US dollars per device group, so cost depends on how many machines you use.
Right for

The original open source slicer, now mostly a base for forks
Ranked #11 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierOpen sourcePublished pricingElsewhere
Slic3r matters for what it started: PrusaSlicer, Bambu Studio and OrcaSlicer all descend from it. The site describes a command-line mode that generates G-code, exports SVG slices and repairs models, and libslic3r lets developers build their own tools.
The AGPLv3 licence is stated plainly. Whether the shown release is current is doubtful, so verify the repository before relying on it.

Volunteer slicer and CAM project that asks for optional support
Ranked #12 of 12 in Best 3D Printing Slicer Software in 2026.
Free tierPublished pricingElsewhere
Kiri:Moto reaches beyond printing into lathe, drill, contour and pocket operations, and exports G-code, SVG, DXF and OBJ. It can connect to OctoPrint, and the site mentions CORS settings for that.
The project says it has been under active development for fourteen years and relies on voluntary support. The missing licence and company details mean it fits personal use more than managed purchasing.

3D printing slicer software converts a digital model into printer instructions, setting layers, infill, supports, speeds and temperatures, then exports G-code or sends it to a printer for filament or resin machines. Feature lists look alike, so we would settle these points one at a time instead.
01
Start with pricing transparency
The split is 10 published against 2 quoted. If you want to compare numbers first, start with OrcaSlicer, PrusaSlicer, Simplify3D, Lychee Slicer, UltiMaker Cura, ideaMaker, MatterControl, Craftware, Slic3r, Kiri:Moto.
02
Ask which country the contract runs through
Where a company is established decides which courts and regulators can reach it. Here that means 5 countries: Elsewhere 7, Europe 3, North America 2.
03
Consider whether you want the source
Source code is available for PrusaSlicer, UltiMaker Cura, Bambu Studio, SuperSlicer, MatterControl, Slic3r. Running it yourself swaps the licence fee for your own upkeep.
Slicer software for 3D printing: two lineages and a few outsiders
Most slicers on this list share an ancestor. Slic3r came first, PrusaSlicer built on it, and Bambu Studio, SuperSlicer and OrcaSlicer forked from PrusaSlicer. UltiMaker Cura is a separate codebase with its own plugin store. Simplify3D, Lychee Slicer and Craftware are independent commercial or freemium products.
This matters because a fork inherits the interface and habits of its parent, so moving between relatives is quick, while moving to Lychee Slicer or Cura means relearning the layout. Check which family your current printer profile comes from, because a profile written for one fork may need conversion in another. Count the printers you run before you choose a family.
Name the family of the slicer you use today.
List which of your printers have official profiles in each candidate.
Test one real job in a second family before committing.
Free, subscription or one-off: where the money goes
Most tools here cost nothing: OrcaSlicer, PrusaSlicer, UltiMaker Cura, SuperSlicer and Slic3r are open source, and ideaMaker and MatterControl are free downloads. Lychee Slicer has a free Lite edition and sells Plus and Library plans monthly or yearly, and Craftware does the same with Standard and Premium.
Simplify3D asks for one published price per user. Free usually means the vendor earns elsewhere: Prusa and UltiMaker sell printers, and MatterHackers sells printers and filament. That rarely harms buyers, but it explains why roadmap priority follows the vendor's own hardware. Weigh the paid tools against the fork that already does the same job.
Write down which paid feature you would actually use.
Check whether ads or limits apply to the free edition.
Ask whether the licence allows commercial use.
Resin, filament or both: matching the slicer to the machine
Not every slicer handles every printer. OrcaSlicer targets FDM only. SuperSlicer slices filament jobs and PNG layers for mSLA printers. Lychee Slicer covers resin and filament in one program, while ideaMaker lists DLP templates for Raise3D resin machines. Kiri:Moto stretches into milling and lathe work.
A workshop with one resin printer and two filament printers either needs one hybrid tool or two programs with separate profiles. Profile coverage varies too: Simplify3D, PrusaSlicer and OrcaSlicer each state support for many printers, but a printer missing from the list means hand-built settings and test prints before the first useful result.
Check each printer against the official profile list.
Decide whether resin and filament will share one program.
Print a calibration test before trusting a profile.
Who maintains it and what happens if they stop
The sources of support differ widely. UltiMaker B.V. and Prusa Research a.s. are companies with their own printers. SuperSlicer belongs to one GitHub user, and OrcaSlicer is led by a creator named SoftFever with contributors. Slic3r's own site still shows version 1.3.0 as its latest news, and Craftware lists builds from February 2023.
Open source licences help here: AGPL-3.0 and LGPL-3.0 let a community continue a project that its author drops, which is how most of these forks began. A paid tool offers a helpdesk but depends on one seller. Look at recent release dates before you standardise on a tool for a team.
Open the repository and note the date of the last release.
Confirm which licence applies and whether commercial use is allowed.
Keep the exported G-code and profiles outside the tool.
What goes wrong most often when buying 3D printing slicer software
Treating a profile from one slicer as interchangeable with the same name in another, then blaming the printer for the result.
Paying for a slicer licence before testing whether OrcaSlicer, PrusaSlicer or UltiMaker Cura already does the job.
Assuming a freshly forked slicer is maintained because its download page looks current.
Choosing a resin slicer for a filament printer, or the reverse, because the site mentions both.
