How long has 3D printing technology been around?
3D printing is much older than you might think! The first patents for an additive manufacturing process are dated all the way back to the 1970s. The first true additive manufacturing patent that led to a product is dated to 1984. The first real-world applications of additive manufacturing are in the dental industry, printing out masks of teeth as a replacement for plaster casting from molds.
What are the benefits of 3D printing?
3D printing is a rapid prototyping process, mass customizable manufacturing process, and a technology that enables the creation of complex geometries previously not possible through other manufacturing processes. It’s also a digital manufacturing technology that requires no tooling changes for revised parts, which means there’s no downtime between product revisions or manufacturing entirely new products.
How much does it cost to 3D print something?
3D printing a part is a combination of the material you wish to use, and the volume. Because 3D printing can output using a plethora of plastics and metals, the cost of a part can vary dramatically depending on what you are using, but it can be more affordable per part than other processes.
What 3D printing services does Autodesk offer?
Autodesk offers Netfabb as a dedicated additive manufacturing prep, analysis, and simulation tool, as well as Fusion 360, which has a dedicated additive manufacturing space, marrying design, engineering, simulation and manufacturing all together.
Fusion 360 is an excellent choice for creating CAD models for 3D printing. It allows you to create not only “prismatic” models such as gears or brackets, but it also allows you create more “organic” models using T-Splines, including characters, plants, and vehicles. You can use Fusion 360 to create and then edit your objects for 3D printing. Bring in models from other software and make modifications, such as de-featuring them by removing small features or blends. Fusion 360 can export as an OBJ or STL file format that is read by most 3D printing software. It also has the ability to print directly to your 3D printer. In addition, Fusion 360 even allows you to edit mesh or STL data that is brought in from a laser-scan or other source. Before printing, you can reduce or increase the surface count, edit out features, fill holes, etc.

The Best CAD Software for 3D Printing (for Hobbyists & Professionals)
Not all CAD software is created equal.
Some excel at technical modeling for applications in fields like engineering and architecture.
Some are more geared towards artistic modeling. Others simplify the process of creating 3D models suitable for 3D printing.
This article will focus on the last category, bringing you recommendations for the best CAD software for 3D printing.
As always, we’ll cover most bases, offering a solution for everyone from the occasional hobbyist with little to no experience to the well-versed professional on the hunt for a program to ease the transition from a 3D digital model to physical print.
How Does CAD Software Work With 3D Printing?
CAD software gives you tools to create a 3D model from scratch that can then be processed, sliced, and sent to a 3D printer for printing.
It’s the starting point from which a fully formed 3D model emerges, a digital blank canvas that allows you to transform an idea or concept into a real-world 3D printed object.
On a more granular level, the best free CAD software for 3D printing allows you not just to create an object or model but export it to a file format, such as STL or OBJ, compatible with and ready for slicing.
3D slicing software then translates the model into a set of G-code instructions interpretable by a 3D printer.
The printer can then print a physical, real-world replica of the CAD software-created digital model.
Best CAD Software for 3D Printers
Blender
- Price: Free, open-source
- Supported 3D Printing File Formats: STL, OBJ
- Operating System Support: Windows, macOS, Linux
Blender is an open-source CAD program that leans heavily towards the artistic side of computer-aided design. It’s one of the most expansive and feature-rich free modeling software for 3D printing.
The software features a potent trove of features and tools suited to creative applications, including modeling, simulation, animation, digital art, video editing, and much more.
Though not innately geared towards 3D printing, the relatively new 3D Print Toolbox and Mesh Analysis features take strides to make Blender a far more 3D printing-friendly program.
Here, the idea is to simplify and process the often very complex polygonal models made with Blender to achieve better 3D printer results.
These new features include a series of checks and fixes that refine and clean up any model for export with 3D printing in mind. These include checking scale and measurement, wall thickness, edges, overhang geometry, support positioning, and hollow areas.
Although not a new addition, Blender also offers export to a selection of the most popular 3D printing formats, including STL.
Aside from this, Blender features a full-fledged modeling and sculpting toolbox to create high-quality 3D models. If anything, Blender suffers from this versatility and comes sided by a hulking learning curve, which means beginners may be overwhelmed by what’s offered here.
FreeCAD
- Price: Free, open-source
- Supported File Formats: STL, OBJ
- Operating System Support: Windows, macOS, Linux
FreeCAD is a free CAD software best described as a Swiss Army knife for all kinds of 3D modeling.
It’s a parametric modeler, meaning every aspect of a model is updated when changing a single parameter, part, dimension, or rule. Despite FreeCAD’s drab interface, the program is a powerful design tool that lends itself well to 3D printing.
FreeCAD works based on Workbenches, or toolsets, with different functions.
In the case of 3D printing, the interesting ones are Part and Part Design, which have a range of sketching, constraint, and modeling functions to create 3D models based on a library of geometric shapes.
There’s also a Mesh Workbench, which contains analysis and repair tools to iron out any potential errors that could lead to a failed print.
From there, FreeCAD allows you to export your model to the STL format, among others, and send it to a slicer program to 3D print cad files.

Best CAD Software for 3D Printing Buyer’s Guide – Things To Consider
What You Plan On 3D Printing
Simply put, this is about complexity and choosing a CAD Software for 3D printing capable of bringing your ideas to life.
While valuable tools for beginners, programs like TinkerCAD can only help you create pretty rudimentary models due to their reasonably limited toolset.
On the other hand, when using professional programs like Fusion 360 and SolidWorks stacked with advanced features, you’re only ever hemmed in by your skillset, experience, and the quality of your modeling ideas rather than the software itself.
In other words, if you plan on creating and 3D printing intricate, feature-rich models, be sure to use advanced CAD software.
The more beginner-friendly options will serve you well if you’re simply testing the waters or only have a basic print in mind.
Your 3D Printer’s Quality and Type
Spending hours modeling a pristine 3D model only to find out your 3D printer isn’t up to the task is not an experience we recommend to anyone.
As such, it’s essential to be well aware of your printer’s capabilities and choose a CAD Software that matches your 3D printing needs.
This is especially important if your model includes overhangs, sharp outward angles, precise surface details, or requires support structures. All these add complexity to the printing process, and not all printers are up to the task.
The type of technology underpinning your printer matters, too.
While cheaper and better suited to larger prints, FDM printers often fail when it comes to printing small, high-detailed models. On the other hand, resin printers excel at doing just that, prized for their ability to pump out high-resolution prints with plenty of fine detail and texture.
Look at your printer’s resolution and minimum layer height to get an idea of what level of detail you can expect.
File and Slicer Compatibility
Consider what file types a particular CAD software for 3D printing supports, especially export formats.
These largely determine compatibility with slicing software. Working hours on a model only to find out the program can’t export to a supported format is something you want to avoid.
As a rule of thumb, opt for CAD software for 3D printing that includes STL exporting at the very least.

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.

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.
The slicer program helps to convert the STL file into a 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.
