How to 3D Print from Fusion 360

Once a Fusion 360 model is finished, it is time to get it 3D printed. However, the finished 3D model cannot print as-is. A 3D printer (or CNC Machine) needs a toolpath or “instructions” to create the model. Instructions are typically in the form of a G-code (.gcode) file. A 3D Printer’s “slicer” must be used to convert the STL file to G-code. Here are three ways to get your 3D model from Fusion 360 and retrieve G-code.

Save As Mesh

Saving an STL (Standard Tessellation Language) file from Fusion 360 is one of the easiest ways to transfer models from Fusion 360 to a 3D printing slicer. This format uses a series of linked triangles to recreate the surface geometry of the 3D model. Use STL files because they are small in size and easy to transfer to 3D machines and software. STL files can also be uploaded and shared with others via online sites like Thangs and Thingiverse.

Exporting STL from Fusion 360

In Fusion 360, right-click on the root (top-level) component, a component, or a 3D body in the Fusion 360 Browser.

Then, select “Save as Mesh” from the right-click menu. This opens the Save as Mesh Fusion 360 dialog, where we can define the export settings.

3D Print from Fusion 360 using the Save as Mesh selection.

Format: We recommend 3MF files over STL files because they include units of measure and some additional metadata.

The Binary option is recommended if you prefer STL files, as it creates a smaller file that is easier to use, share, and store. Both Binary and ASCII will use the same number of triangles and quality, so the smaller file is preferable.

3D Printing: STL files are unitless, so it’s critical to know what unit of measurement the Slicer of software program will expect. See Why is STL 10 times larger than expected.

Structure: If you are printing a model which is already arranged per the print, then the structure should be set to one file. If the model will be arranged as individual parts, then One File per Body will save each body as an individual STL, saving some time by creating multiple files.

Refinement: If the model contains organic shapes and many curves, then a higher refinement may be required, which will increase the number of triangles saved in the STL. This gives the STL higher resolution but increases the file size.

After defining the settings, select OK to save the mesh file.

Importing STL to a Slicer Software

Many 3D printing companies have software that they recommend when using their 3D printers, such as Cura or Prusa Slicer. In addition, slicers often include templates for common makes and models of 3D printers.

After opening your chosen Slicer, click on the import button (or go to File > Import) and select the STL file from your computer.

Select Slice – note that some slicers automatically do this.

Then save the G-code to your computer or an SD card, depending on your printer’s setup.

Send to Print Utility

If you would like to 3D print immediately – it is possible to skip the STL export by sending it straight to your chosen slicer.

Select Tools in the toolbar (of the Design Workspace), select Make, then 3D Print. The 3D Print feature will open the same dialog as Save as Mesh.

Check the “Send to 3D Print Utility” in the 3D Print/Save as Mesh dialog. Note that the first time you will be required to select the Application from your computer’s folders.

Once you select OK, Fusion 360 will open the Slicer with the part in the print bed. Double-check that your settings are correct before slicing and saving the G-code.

Send to 3D Print Utility allows you to 3D Print Fusion 360 files using your chosen slicer.

Slice Directly in Fusion 360

Fusion 360 is a CAD/CAM package that helps you quickly go from design to manufacturing. It’s no surprise that they also allow users to set up additive manufacturing files for 3D printing directly in Fusion 360.

This workflow allows users to get the G-code file without the use of external slicers.
Start by switching to the Manufacture workspace. Select the workspaces dropdown in the upper-left, followed by selecting Manufacture.

Select the Additive tab in the toolbar. Then, select the Setup feature, which opens the Setup dialog.

Fusion 360’s Manufacture workspace includes additive functionality to 3D Print from Fusion 360.

Machine: Select the 3D printer to be used.

Print Settings: Fusion 360 offers preset settings for each printer. If you don’t find your machine (3D Printer) you can create a custom machine.

Setup: For Operation Type select Additive.

Arrangement: Automatic should be checked.

Model: Select the bodies that are going to be 3D printed.

Select OK.

A new setup has then been created. Right-click on the Additive Toolpath and click generate. There will be a bit of loading, and then you will be able to see how the model is being sliced by selecting Simulate Additive Toolpath.

After defining your print settings, select “Post Process,” then Post. This will allow you to save the G-code to your computer.

Save as Mesh (STL) Summary

STL files are the most common file for 3D printing due to their file size and wide acceptance from 3D printer slicers. STL files are small in size and a storage-friendly way to transfer models between different users.

In Fusion 360, sending your model to 3D Print Utility is a quick way to send the 3D model to a slicer without the need to export an STL file. This streamlines the workflow and prevents clutter in your computer storage.

Using Fusion 360’s built-in slicer is a great way to maximize efficiency, allowing you to automatically update toolpaths after making critical design updates.

3D Printing Basics: A Beginner's Guide

This post is also available in: Deutsch (German)

Check out this comprehensive guide to 3D printing and 3D modeling basics. Learn about important terminology you should know, 3D printers, and extremely fast cloud CAD software.

Whether you are an up-and-coming college student or a veteran engineer, learning or revisiting the fundamentals of three-dimensional (3D) printing is extremely valuable. 3D printing isn’t just a futuristic dream anymore. Industrial designers often use 3D printing to create prototype scale models to test their design’s form, function, and fit. 3D printers are as versatile as ever with various features, materials, and applicable 3D software packages like Autodesk Fusion 360.

Designers typically have a design (or dream) in mind to begin. 3D printing helps bring that dream to fruition. This article discusses the fundamentals of 3D printing to help you go from dream to done in no time.

What is 3D Printing?

3D printing, also known as additive manufacturing, is printing a 3D object from a digital design. Unlike traditional subtractive processes, 3D printing is an additive process. It takes a solid object and then carves or reduces it into the ideal design. Essentially, the 3D printer uses a digital blueprint to mold a physical product. For example, some 3D printers use a heated material, like plastic, to create a layer on top of other layers, which eventually stacks up in three-dimensional space to create an object.

3D printing was introduced in the late 1980s but didn’t draw serious attention until the 1990s. As with any new technology, many people saw 3D printing as only possible in science fiction. However, 3D printing gained traction and is now being integrated into several industries.

3D printing Terms and Definitions

It’s helpful to understand the vernacular associated with the 3D printing process before diving into the wide world of additive manufacturing. Not every term can be listed or understood in one blog post, but the list below should help you kickstart your project. 

  • Additive manufacturing: Another term for 3D printing. The process of adding materials to create a physical object.
  • Bed leveling: The process of leveling a 3D printer’s build plate.
  • Bowden extruder: An extruder type for FDM printers that has a separated hot end and extruder motor.
  • Computer-aided design (CAD): The process of designing parts or other objects in a digital environment before 3D printing.
  • Computer-aided manufacturing (CAM): The process of using software and computer-controlled machinery to automate a manufacturing process.
  • Curing: The process of using UV light to solidify liquid resin.
  • Digital light processing (DLP): A printer that projects light over an entire layer to cure the resin all at once.
  • Direct drive: This device is different from the Bowden extruder because the extruder motor sits on top of the hot end.
  • Elephant’s foot: A common problem where the first layer is distributed wider than needed. This problem can be solved by adjusting the 3D printer settings.
  • Extruder: A motor with gears that feeds filament to the printer’s hot end.
  • Filament: Material used in 3D printing.
  • Fused deposition modeling (FDM): A 3D printing method where material layers are fused together in a specific pattern.
  • G-Code: The language used to create commands for 3D printers.
  • Hot end: Consists of a heating cartridge and a thermistor to heat the filament.
  • Infill: This is the interior of the printed object. Infill patterns vary and help provide adequate internal structure to the printed object.
  • International Organization for Standardization (ISO): A worldwide standard of quality management for any organization.
  • Liquid crystal display (LCD): A printer that uses an LCD screen to mask a projector’s light or uses its own light to cure an entire layer at once.
  • Selective laser sintering (SLS): An industrial 3D printing process that uses a laser to fuse a thermoplastic powder to build prototype parts.
  • Stereolithography (SLA):A printer that uses a laser to cure liquid resin with pinpoint precision.
  • Striping: Striping is a common problem with FDM printers where individual layers become visible in the end product.
  • Thermoplastic: A type of plastic made of polymer resins that soften when heated and hardens when cooled.
  • Vat Polymerization: Resin-based 3D printing where liquid photopolymer resin is stored in a vat (unlike other printers that force thermoplastics through a nozzle). Subcategories of vat polymerization include stereolithography (SLA), digital light processing (DLP), and liquid crystal display (LCD).

3D Printers for Beginners

A 3D printer operates on the X, Y, and Z-axes:

  • The X-axis is the left-to-right movement.
  • The Y-axis is the front-to-back movement.
  • The Z-axis is the upward and downward movement.

The extruder is installed on the X-axis and feeds filament onto the build plate (print bed). The build plate is often heated and can adjust for leveling and temperature.

Types of 3D printers

There are several types of beginner-friendly printers on the market. The most common are FDM, SLA, and SLS printers. FDM printers are generally the cheapest option for beginners or homebrewing engineers. They are easy to maintain and filament to feed the machine is relatively affordable compared to the other two options. The downsides of FDM printers include clogged nozzles, difficult clean-ups, and striping.

SLA printers utilize liquid resin hardened by UV light to create a final product. These printers are great for intricate details (down to 25 microns) but cost a few thousand more than FDM printers. Disadvantages of SLA printers include clogged nozzles, limitations on available materials, and final products that can be potentially brittle.

Lastly, there are SLS printers. The main difference is that SLS printers use powder instead of liquid resin. These printers are the most expensive and generally cost over $50,000. However, they provide detail down to 16 microns and do not require infill patterns for stability. SLS printers can use materials other than resin, like aluminum, silver, or steel. Naturally, the biggest disadvantage is the price tag.

Choosing the right printer can be a difficult task, but the choice lies within the application. What will you use your printer for? Determining the printer’s application, cost, and size will all factor in your decision. Companies like Formlabs can provide specifications and factor individual costs for printers and associated equipment.

But a 3D printer is useless without proper software.

The Ideal Software for Beginners

Just like 3D printers, CAD software comes in various shapes and sizes. For example, Autodesk Fusion 360 provides an integrated, easy-to-use cloud CAD environment for beginners and experts alike. If you’re not ready to purchase a 3D printer or CAD software, consider utilizing Xometry’s industry-leading 3D printing services. Xometry provides an online marketplace for engineers or regular people to create or have something created.

Go from dream to done with Fusion 360 today!

Start printing directly from Fusion 360

Although many people are skeptical about the slicing functionality in Fusion 360, I have only been using it since its release (I think March 2020). In the next few articles, I want to tell you exactly what you need to do in order to get the G-code of your model directly from the fusion.

In the first part, I will outline the algorithm of actions for generating code in large blocks. Then we will do an interactive stream, and after that there will be one or more articles detailing the incomprehensible steps.

First, the model itself is needed. We assume that the part is already made, saved in one of the projects in the cloud and ready for printing.

Next we have to go into Manufacture mode, just click on Design and select Manufacture there. We will find ourselves in a new mode of operation with the same model.

Once again, an important thought - the model does not change, it is not transferred / uploaded / exported anywhere. The geometry remains the same, we just change the mode of working with it and the tools.

Cool fact #1 - printing from fusion makes it possible not to export / import the model, we do not divide the model into the "solid state for editing", "stl for printing" stages. Within the same system, we work with the same model with different tools. We simply switch between Design/Manufacture modes and, accordingly, alternately get model editing tools and code generation tools

After switching to Manufacture, the concept 9 becomes key for us0015 Setup . This thing is well known to those who work on CNC machines, and we also have to deal with it.

When we are preparing the print, in the setup we need to put together the following information: we set it by creating in the library (once) and then selecting (each time when creating a setup) our printer ( Machine ).

For other CNC systems, the Machine setting is optional, but for printing (i.e. additive operations) it is critical. All machine descriptions are stored in the library. The car needs to be created in advance, before creating the first setup, but next time you can just select it from the library.

The following is written in the machine:

  • the number and parameters of extruders
  • the presence of airflow model
  • table dimensions
  • where to park the head after printing
  • and, of course, the name and text description

In general, everything that describes the printer geometrically and gives an idea of ​​its maximum capabilities.

A good practice to create your own machine is to (1) take one of the already prepared descriptions (2) copy it to your library and (3) fix it to fit your needs.

The library, for example, already has Ender 3. If your printer is not there, then just copy the default " Autodesk Generic FFF Machine ".

In my case, the set of edits was minimal - table dimensions, parking coordinates and description.

The second part of the setup, "what to print" - is indicated in paragraph Model and there you can select the entire model, component (or several)

Important fact #2 - if you are printing a multi-part model, you need to make sure that each part is in its own component.If this is not done, then fusion will work with the entire group as with one part and you will not be able to lay out individual parts on the table.Positioning tools - Move, Arrange, Automatic Orientation and Place part on platform work only with 9 components0017

And finally, the third part of the setup, "with what settings to print" - this is called Print Settings and in organization this thing is very similar to Machine:

  • they also need to be done in advance, before creating the setup
  • they are also stored in the library
  • you can also take them from the default ones, copy them to yourself and fix them
  • you can also create as many as you need and then just select from the library

All print settings are stored in print settings:

  • temperatures
  • speeds
  • or not (and which ones) - BRAM, SKIRT, RAFT, support
  • Perimeters settings, filling
  • and so on, and so on
9000 9000
Important fact #3 - PRINT settings can be changed directly inside the setup, these changes only affect the current setup. For example, you have an ABS profile with temperatures/speeds, but in this model you want the speeds to be different - you can easily change the settings after creating the setup and do not spoil the profile stored in the library

In total, when you put all three parts together and created a setup, you get this element

After that, you shamelessly use all the available tools for positioning parts, among which there is a wonderful Automatic Orientation, which I will talk about someday later

You can change the print settings for this setup as you like without fear of damaging the saved profiles

And most importantly, you must do two things.

First, generate an extruder path ( toolpath ) for a given setup (i.e. machine + model + settings) process (3) trajectory is ready

Naturally, this procedure must be done every time you change something in the settings or setup. The rule is very simple, we see an exclamation mark - it means we need to regenerate the trajectory.

And the second important thing - you check the resulting trajectory in the built-in simulator. P-time:

Two:

Remarkable fact #4 - you can create as many setups for your model as you like. This may be necessary, for example, if you print different parts with different settings, I do this when some need to be printed with supports, and some without. We simply create a new setup, select only those components in it that should fall into it and set our own settings in the setup

When you visually got what you need, only one step separates you from the G-code - post-processing .

The point is that the toolpath you see is not code yet. These are geometric lines, displaying the movement of the extruder, but not the code. The code is generated by a postprocessor, which is essentially a JavaScript program (but you don't need to understand these subtleties at all).

So, post-processing. When the toolpath is ready and you are satisfied, do this

Then like this:

Then like this

And that's it. Press Post, show where to put the file, save. The code is ready.

In a nutshell, what we just did:

  1. select the library of pre-installed post processors
  2. select the default "Generic FFF Machine" post from it
  3. upload the code through this post processor

This whole process can be made easier, faster, better, etc. - you can make your own postprocessor and put it in your own library; you can specify in the Machine settings which post to use for your printer and where exactly to put the files with the code. And so on.

There are a lot of opportunities to flexibly bend the process to your liking.

After creating all the setups and settings, don't forget to save, because there is

Cool Fact #5 - fusion printing makes it very easy to iterate. After creating the setups and checking the settings, we can switch to Design mode and edit the model. After returning to Manufacture, we just need to click Generate toolpath to get new toolpaths for the modified model.

In order to discuss all this, I will organize a stream, where I will additionally present a custom post-processor, in which it is possible to use a second extruder to print the model and flexibly set the percentage of airflow 😊

That's all for now. Write in the comments what is not clear, come to the stream, ask questions.

3 Useful 3D Printing Applications for Fusion 360

Additive Assistant tool for Fusion 360

You've probably already explored the 3D printing capabilities of Fusion 360, and if not, you're missing out. From FFF printing to metal powder additive manufacturing, Fusion 360 tools are evolving at a rapid pace, with even more new features coming towards the end of the year.
