Top 20 Free 3D Printing & 3D Printing Software

Looking for 3D printing software? We've rounded up the top 20 software tools for beginners and professionals alike. Most slicers are free.

What is a slicer? This is a program for preparing a digital model for printing. Models for 3D printing are usually distributed in STL files. To turn an STL file into G-code (a language that a 3D printer understands), a slicer program is required. It is called a slicer because it cuts (to slice - English) a 3D model into many flat two-dimensional layers, from which a 3D printer will add a physical object.

Which slicer should I choose? In this article, we will tell you which slicer is best for 3D printing for each stage of your work. Which one is better for preparing a 3D model for printing? But what if you need to create a 3D model from scratch? And if you are only taking the first steps in 3D?

Don't be afraid: we've answered all of these questions, including the required skill level for each program and where you can download it. The great thing is that most of these programs are completely free and open source.

#15: Simplify3D

For professionals to prepare STL files for 3D printing print. A flexible algorithm checks the model for problems, fixes them, shows a preview of the printing process (ideal for identifying potential problems), and then slices it.

This slicer offers the best infill pattern options in the competition. For models that require supports, Simplify3D will create the appropriate structures on its own and give you full control over their placement. For printers with a dual extruder, when printing with different materials, the Dual Extrusion wizard will help, as a result of which, for example, it will be easier to remove the dissolving filament.

Simplify3D supports 90% of today's commercially available desktop 3D printers and is compatible with Marlin, Sprinter, Repetier, XYZprinting, FlashForge, Sailfish and MakerBot firmware. Simplify3D can also be used to directly control the printer, but then the printer and computer must be connected to each other.

Top Free 3D Printing Software in 2021 zero? What software is best for beginners? All these questions can be answered in our article. The applications presented in the review are completely free or have free versions for students, teachers and open source projects.

Why did we put this section before all the others? The answer is very simple. By knowing the whole 3D printing process, you can better understand how each software is involved in the preparation and printing of 3D parts.

If you have become a happy owner of a 3D printer, but have absolutely no idea what to do with it and how to get started, then this part of the article is for you.

Different programs are used to print 3D models:

3D modeling/design/CAD software;

Software for editing, viewing and restoring STL files;

Slicing software;

3D printer host.

Before starting work, you need to create a 3D model. To do this, you can use different programs for modeling. We wrote in detail about free versions of software for 3D modeling here.

A small life hack for beginners. If you are not ready to create a model on your own, you can choose and download the right one from the marketplaces. There are also free download links in the maker communities - sometimes the proposed 3D models can be not only interesting, but also useful.

Once a 3D model has been created, it must be converted to a printable format. For desktop 3D printers, this is the STL format. Some created or downloaded files have defects that lead to failures during printing. It is for editing STL files that there is special software that helps prepare the model for playback on the printer.

Slicer software helps to convert STL file into printer friendly G-code. The functionality of such programs allows you to split a 3D model into thousands of flat 2D layers, which will be sequentially reproduced on a printer.

Finally, the 3D printer host provides communication between the computer and the printer. It allows you to receive information for printing, as well as change the parameters of the device in real time via a PC. Often the Slicer and host are combined into one 3D printing software that is supplied by the printer manufacturer.

Dear readers of the 3DToday portal, we want to inform you that a new section "Knowledge Base" has been opened on our website of the LIDER-3D online store. In this section, we share owls, experience, settings and secrets of the world of additive technologies, go to the section at this link.

Examples of some already posted articles in the Knowledge Base section: Post-processing of models after 3D printing, 10 calibration models for your 3D printer, How and what 3D printers print, Printing with HIPS plastic, ABS printing settings, Recommendations for Resin Post-Processing HARZ Labs, Best Free 3D Modeling Software for Beginners.

Cura
