Features

Compatible with your printer too. RepRap (Prusa Mendel, MendelMax, Huxley, Tantillus...), Ultimaker, Makerbot, Lulzbot AO-100, TAZ, MakerGear M2, Rostock, Mach4, Bukobot and lots more. And even DLP printers.

Fast G-code generation is fast. Don't wait hours for slicing that detailed model. Slic3r is about 100x faster than Skeinforge. It also uses multithreading for parallel computation.

Lots of input/output formats. Slic3r reads STL, AMF and OBJ files while it can output G-code and SVG files.

Do you like the graphical interface or command line? All the features of the user-friendly interface are also available from command line. This allows to integrate Slic3r in your custom toolchain and batch operations as you like.

Open source, open development. Slic3r is open source software, licenced under the AGPLv3 license. The development is centered on GitHub and the #slic3r IRC channel on FreeNode, where the community is highly involved in testing and providing ideas and feedback.

Dependencies? Nah. Slic3r is super-easy to run: download, double click and enjoy. No dependencies needed. Hassle-free. For MacOS X, Windows, Linux.

Print with dual multiple extruders. Print beautiful colored objects, or use your secondary extruder to build support material. Or put a larger nozzle on it and print a faster infill.

Use brim for the best adhesion. This unique feature improves built plate adhesion by generating a base flange around your objects that you can easily remove after printing.

Microlayering: save time, increase accuracy. You can choose to print a thicker infill to benefit from low layer heights on perimeters and still keep your print time within a reasonable amount.

Compose a plate but print one object at time. Use the built-in plating interface that allows to place objects with drag-and-drop, rotate and scale them, arrange everything as you like. The sequential printing feature allows to print one complete object at time in a single print job.

Cool cooling strategies. A very smart cooling logic will regulate your fan speed and print speed to ensure each layer has enough time to cool down before next one is laid on it.

Manage multiple printers, filaments and build styles. The configuration handling system was designed for people working with multiple machines and filaments: you can save configurations as presets for each category avoiding to multiply your saved configurations.

Enjoy support material. Automatic generation of support material for overhangs.

The 5 Best G-Code Simulators for Machining and 3D Printing

A good G-Code simulator can make the difference between a successful manufacturing process or an expensive failure. Here are some of the best simulators.

Debugging is a vital part of any programming task. This is certainly true with programs that will interact with the physical world like those used to control CNC machines, 3D printers, and robotics.

Any mistake in the programming of these physical machines could cause real damage to the environment, the machine itself, and even to human workers in the case of some robots.

G-Code simulation is probably the best way to ensure that you have written your program to a high standard. Although very few people these days write G-Code by hand — we tend to use CAM programs — there is still a huge benefit to checking your program in a simulator before loading it into your physical machine.

Here is a list of some of the best types of G-Code simulator that you can use these days.

What is a G-Code Simulator?

A G-Code simulator is a type of software tool that provides a virtual representation of a CNC machine’s tool path made by following the instructions in a G-Code file. They range from simple simulators that output a single image of the tool path to complex tools that can detect collisions and plot the path in 3D.

The basic purpose of a G-Code simulator is to give you a way to see how the machine tool will move. Without this, the only way to debug your program is to test it out on the machine itself… and by then it’s too late to avoid disaster.

G-Code simulators have experienced a resurgence in popularity over recent years thanks to the rise of 3D printing. Hobbyists and professionals alike need a way to see a 3D printed item before they spend hours printing it. A good simulator provides a quick and easy way to achieve this.

The 5 Best G-Code Simulators for Machining and 3D Printing

There are quite a few options for simulating your G-Code out there. Some of them are okay, others are a waste of time.

Here are 5 types of G-Code simulator that are all good in some situations. Which you pick depends on your unique needs for this machining or 3D printing application:

1.

Stand-alone G-Code Simulator

There are some simple software tools available that will quickly simulate your G-Code file and show you the path. In general, they don’t interface with CNC machines or 3D printers, but they at least give you the confidence that your program “draws the shapes” that it’s supposed to.

Some notable examples include:

  • NC Viewer a handy online tool for quick visualization.
  • CAMotics an open-source simulator for 3-axis machining.
  • G-Code Q’n’dirty another open-source web tool.

2. Slicer Software (for 3D printing)

If you are using G-Code to program a 3D printer, your Slicer software may be able to give you a visualization of what the final printed item will look like.

A Slicer is a software tool that turns your CAD model into G-Code.

For example, RoboDK users often use the free tool Slic3er when they are using robotic 3D printing. This tool allows them to visualize the item that they are going to print before they send it to the robot.

Slic3r can also perform some of the functions of a dedicated G-Code simulator, such as estimating the time it will take to print the object and repairing incomplete 3D files.

3. RoboDK for Robotic Machining and 3D Printing

If you are considering using a robot for your machining or 3D printing, probably the best option is RoboDK (of course, we would say that, wouldn’t we?… but it’s also true).

RoboDK’s machining and printing wizard works with G-Code.

You can load a G-Code file into the software then easily simulate the path. Then, with the same software, you can send the program directly to the robot’s controller, without having to do any robot programming at all!

Didn’t know robots could do 3D printing? Here’s a video:

4. Libraries (e.g. MATLAB or Python)

There are some situations where you might want to perform some more advanced analysis on your G-Code or link with your own programming. Perhaps you are using the code as part of a research project or you are developing your own 3D printer.

In such cases, it could be helpful to use a G-Code library for your preferred programming language.

For example:

  • G-Code Reader is an extension for MATLAB.
  • PyCNC is a library for Python.
  • Gsim is an open-source 2D simulator written in Python.

5. Your Favorite CAM Package

Computer-Aided Manufacturing (CAM) programs are how many of us generate our G-Code files in the first place.

Popular CAM packages (which also include plugins for RoboDK) include:

  • MasterCAM
  • Inventor
  • Fusion 360

Many of the leading CAM packages also have the capacity to simulate your G-Code. Often, if you want to link the software directly with your CNC machine or 3D printer, it will require you to purchase an extra add-on license, so weigh up the pros and cons beforehand. However, simple simulation can usually be achieved within the CAM software itself.

How to Pick the Best Software for You

There are clearly several ways to simulate G-Code!

But, which is going to be the best software for you? The answer depends on your situation.

If you are a hobbyist who is just using G-Code to program your home 3D printer, for example, one of the open-source, stand-alone simulators or Slicer software will probably be the best option.

If you are a researcher or programmer looking to delve deep into the simulation, one of the MATLAB or Python libraries might be worth checking out.

Finally, if you are working in industry, however, you will want a piece of software that is easy to use, robust and won’t give you any unnecessary headaches. For robotic machining or 3D printing, RoboDK is a good option. For all other CNC, look at a decent CAM package.

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 10 Free 3D Modeling Software of 2019

3D Modeling Has Many Uses: Thanks to it computer graphics, realistic video games are created, tests are carried out, prototypes are created. Every year 3D-modelers are becoming more and more in demand - but where to learn it?

We've rounded up the top 10 free programs with the latest tools in 2019 to help you practice creating 3D models.

3D Slash is a 3D modeling software that allows you to create models using a simple building block concept.

This service is much simpler than its counterparts: users create 3D structures by working on a cuboid using a variety of 3D modeling tools: Hammer, Spatula, Chisel, Wood and Drill - for many, the creation process models in 3D Slash are somewhat reminiscent of Minecraft. 3D designing with these tools will be easy even for beginners. 3D projects in the program can be imported and modified.

However, note that by default the tools will give the model "pixel prints". If you prefer crisp edges and smooth surfaces, select tool sizes below your printer's resolution.

LibreCAD is a free and open source 3D modeling software. Contains the basic tools you will need to model and modify projects. The user interface of LibreCAD is not overloaded, so this 3D modeling software is suitable for beginners.

It should be noted that the service only displays 2D views, so the size of the source file will be only 30 MB. Also, in addition to 2D, the service can display isometric images.

Meshmixer 3.0 is a program that allows you to design 3D prototypes by combining several models. Users can cut the desired parts from the models and paste them into others.

In addition, the program allows you to create sculptures and prepare your prototypes for printing. The program is available on Windows and OS X.

SculptGL is the perfect option if you want to learn how to create organic 3D sculpting. The whole process of building models in this program resembles clay modeling.

Using dynamic topology modifiers, you can subdivide a 3D model to create more complex details, and importing a base mesh can save you a lot of time.

The software runs on WebGL, so it opens without problems in most browsers. It also has limited functionality - just a couple of brushes that mimic real sculpting tools. But in this case, it's more of a plus than a minus.

The intuitive AutoDesk 123D software offers a variety of 3D modeling and CAD tools. In addition, it supports 3D printing and laser cutting technology. The software is available on Windows, MacOS X and iOS.

Houdini Apprentice is a free version of Houdini FX with fewer tools. It is suitable for artists, students and amateurs who create three-dimensional models. Houdini Apprentice has a simple and intuitive interface, so the program will be useful for beginner 3D designers as well.

TinkerCAD is software that helps you create complex designs effortlessly. Recently, the TinkerCAD development team has added the ability to design objects using Codeblocks, allowing for more technical parametric modeling. Thanks to him, the quality of 3D models will not depend so much on how well you use the mouse and keyboard.

Wings 3D is a simulation program with many tools to create realistic prototypes. With its help, you can texture models - the built-in AutoUV tool helps with this.

The program does not support animation and represents only one OpenGl render, so it is often used in combination with other programs. Wings 3D uses the Erlang programming language and is available on Windows, Linux, and MacOS X.

This free software includes many common CAD modeling tools, but they are beyond the beginner's grasp. The user interface is clearly inspired by AutoCAD, so DesignSpar is a good alternative for 3D modelers who would like to use this software but can't afford it.

While the basic features of this software are free, the publisher charges for additional features such as advanced import/export and rendering options.

Like some other programs, DesignSpark connects to online services. In particular, it allows you to load 3D models directly into free CAD software, as well as print and mail designs.
