Software for creating 3d printing

Software for 3D Printing - 3D Modeling Software/Slicers/3D Printer Hosts

An Overview Of The Best 3D Printing Software Tools

Every 3D print begins as a 3D model generated in a modeling program. Years ago, we had to spend lots of money and time to acquire and learn modeling software. Now, there are many easy-to-use modeling software options available, many of which are free. This list includes some of the best options and is sorted by price, with the free ones sorted alphabetically.

The list also indicates whether the software uses solid modeling, a type of 3D modeling that always generates models that are “manifold” or “water tight.” A manifold model is one in which all walls of the model have some thickness, which is necessary for 3D printing. By contrast, software that uses polygon modeling can generate walls that have zero thickness; that’s fine for creating computer graphics for games and movies but not useful when 3D printing the models. Manifold models can be created with polygon modeling software, it just takes more steps and experience. All the software in this list can create 3D printable models, but every model that comes out of solid modeling software is 3D printable.

Additionally, we’ve noted what skill-level of user each software is designed for: beginners, amateurs, advanced users, and professionals. In general, the easiest to use options are near the top and the most powerful options tend to be near the bottom, though there are some outliers found throughout. Most of these software can be tried for free and there are free tutorial videos available for all of them.

Now we move on to SolidWorks. This is a CAD program often used by professional 3D designers. There are a plethora of advanced features included, such as design validation tools and reverse engineering. Solidworks comes in three distinct packages, depending on the exact features you need.

Solidworks tends towards the industrial side of things. It is practical and detailed. While most software, mimic curves through gently inclining flat structures, Solidworks uses a system of nurbs that create averages of the edges to produce fantastically detailed curvatures. It only does away with polygonal modeling, opting instead for dimensional sketching. As a result, resizing becomes far less of a hassle.

Maya

• Price: $1,545/year
• Solid modeling: No
• Intended for: Advanced users and professionals
• What makes it special: Procedural effects and powerful world and character creation tools.

Primarily marketed at animation professionals, Maya is useful for many aspects of 3D modeling, especially in terms of mathematically smooth surfaces and shapes. Maya was originally slated as a 3D animation software, but is very useful in 3D printing as well. Thus, a lot of the interface options are more reminiscent of sculpting and animation.

Maya is more applicable to artistic printing requirements. It has a fast rendering engine and is best for highly detailed models with many intricacies. The downside is that it is very expensive (it is, after all, the same software used for high-budget movie CGI|). Nonetheless, it allows for realistic representations of reflection and colour on a software with smooth operation.

One of the great things about Inventor is how they improve the software with user feedback. New versions include improvements to visual data representation and the ability to easily reference 3rd party designs without the need to convert file formats.

Slicers & 3D Printer Hosts

The second section of this list of the best 3D printing software tools focuses on programs that help you to execute a 3D print. Slicers are the easiest way to go from a 3D model to a printed part because they take a CAD model, slice it into layers and turn the model into G-code. The slicer software also includes 3D printer settings like temperature, layer height, print speed, etc. to the G-code. The 3D printer can read this G-code and make the model layer by layer following the instructions set in the G-code.

Ultimaker Cura

Despite its name, Cura can be used with almost any 3D printer because it is an open-source slicer. The program is ideal for beginners because it is intuitive and fast. Most of all, it’s easy to use. More advanced users can access a further 200 settings to refine their prints.

Simplify3D

Simplify3D is an extremely powerful premium slicing tool that helps you drastically improve the quality of 3D prints. Not only does Simplify3D slice your CAD into layers, it also corrects any problems with your models and allows you to preview the end result, helping to further identify any other issues. Advanced users will need to decide if the premium features are worth paying for compared to open-source slicers.

Slic3r

This open-source software includes real-time incremental slicing, 3D preview, and more. It is one of the most widely used 3D printing software tools. The incremental real-time slicing ensures that when you change a setting, the slicing doesn’t need to start from scratch. Only the G-code for affected parts is recalculated. The end result is a fast, flexible, and precise slicing program.

Repetier

This open-source slicer software supports three different slicing engines; Slic3r, CuraEngine, and Skeinforge. Repetier can also handle up to 16 extruders with different filament types and colors simultaneously, and you can visualize your end result before printing. There is a lot of customization and a lot of tinkering involved, making Repetier ideal for more advanced users. You also get remote access to your printers with Repetier host.

KISSlicer

This slicing software does its job well, although the user interface is somewhat basic. Still, if you just need a slicer that delivers great results, use KISSlicer. Note that the basic version is for single-head machines only. You’ll need a PRO version for multi-head machines.

ideaMaker

This free slicer is distributed by Raise3D and provides fast, simple slicing for most 3D printers. Team members can share print profiles and supports can be automatically or manually placed. The adaptive layer height tool allows the software to adjust layer height depending on the level of detail in the model, maximizing print quality while minimizing print time. Remote monitoring and control is also available.

OctoPrint

A free open-source web-interface that allows for remote control and monitoring of 3D printers. It’s compatible with most 3D printers and allows users to watch their prints with an embedded webcam feed. Prints can be started, paused, and stopped remotely, and plugins are available to track print statistics and send push notifications on job progress.

3DPrinterOS

This nifty cloud 3D printer management software comes at a cost. The essential idea is the management of the entire 3D printing process with one platform. Users can edit and repair designs, slice STL files from the cloud, and even send files for printing from anywhere in the world. The software also features the capability to share CAD files.

What software to use for 3D printing: The complete guide

David Roberson13 May 2021

Guide

Before starting to 3D print, you will need to make sure you have gathered all the necessary software “ingredients” that will guide you through the printing process, from preparing your 3D model to managing printers themselves.

These include:

• CAD software to create a 3D model (you can also use an existing 3D model, if you do not wish or need to design one)

• Slicing software

• Software to operate your printer remotely (this is optional, but can be convenient)

This article will go through each of these ingredients, and will also touch on how the Ultimaker platform creates a seamless end-to-end flow between hardware, software, and materials, empowering you to unlock the magic of 3D printing and make innovation happen.

What is a “slicer”?

A 3D printing slicer – also known as slicing or print preparation software – is a program that converts a 3D model into a language your 3D printer understands.

Slicing software, such as Ultimaker Cura, digitally cuts a model into flat layers, which your printer can then print one by one. With the Ultimaker platform, however, slicing software is not always needed, thanks to integrations that allow you to print directly from CAD or the Ultimaker Digital Library.

Preparing a 3D print using Ultimaker Cura software

CAD, or computer-aided design, software enables you to design a 3D model from the ground, up. There are many types of CAD software, each with its own benefits. AutoCAD, created by Autodesk, is perhaps the best-known among them since it was one of the first CAD software programs available for personal computers when released in 1982. Other CAD platforms include:

• Fusion360 – great for designing and creating efficient mechanical parts

• 3ds Max – used in all types of 3D model creation, including video game design, architecture, and 3D printing

• TinkerCAD – A free, browser-based CAD tool that allows users to build 3D models out of various shapes. Popular with CAD novices and for STEAM education

• Blender – free, open-source 3D model creation software

• Siemens NX – for designing and creating advanced 3D models

• Solidworks – for designing and creating professional parts for industrial use

• Catia – Advanced design software used for creating surfaces and engineering systems

Before you begin 3D printing, be sure to do your research and pick the CAD software that’s right for your use case. This way, you’ll get the most out of the model you choose to design and print.

Also check which file types your slicing software is compatible with, so you can make your 3D designs into 3D prints.

How to design parts for 3D printing?

When designing for 3D printing, there are best practices to help you get the best results from your 3D printer and the parts it creates. Design parts optimized for 3D printing will improve print success rates, reduce costs through lower wastage, and boost the speed of your product development cycle.

Consider build volume. Your 3D prints can only be as large as your printer’s build volume. Be sure to know its dimensions, then create a part that can either be printed within those dimensions in one go, or plan to use modularity (printing then combining separate parts). 

Decide orientation early. Because FFF prints layer by layer, determining the print orientation early in the process helps drive design choices, text alignment, and snap features.

Evaluate overhang support requirements. FFF printed parts are self-supporting up to 45 degrees. Overhangs below 45 degrees must be supported from below with support material.

Follow bridging support guidelines. For most basic filaments, FFF printing does not need support when bridging materials within a 10 mm gap. 

Pay attention to nozzle size. When designing small features, you should consider height, wall thickness, and nozzle size. Larger nozzles will print faster than smaller nozzles, but at a cost of increased minimum thickness and height for your models.

Design with hole diameters in mind. Generally, 3D printed hole features should not be smaller than 2 mm. If accurate holes are required, it is recommended to design the holes smaller than intended and post-process with a drilling operation. 

Avoid sharp corners. Sharp corners can be modelled in CAD, but the print may warp. Increasing the area of the surface in contact with the bed will decrease the likelihood of the warpage.

For a deep dive into these factors and more, check out our blog on design for 3D printing.

What software do I need to start a 3D print?

This depends on how much of the 3D printing workflow you need to perform.

As long as you already have access to a 3D model, you will typically need software that can slice that model, so your printer can get to work. Once you have started to print, you can also use software to manager your 3D printer (or printers) remotely.

But as we saw earlier, the slicing step can be avoided if you have a 3D printer integration installed in your CAD tool. If you already have access to a 3D printable file (such as a G-code on a USB stick) you can also go ahead and print without the need for any slicing software, as your digital file is already ready to print.

Controlling 3D printers remotely with Ultimaker Digital Factory software

Managing 3D printers remotely

Ultimaker S-line printers, the Ultimaker 2+ Connect, and the Ultimaker 3 can make use of a network connection to access cloud-based services on Ultimaker Digital Factory. By linking a printer to your Ultimaker account, your printer can then be controlled remotely, from outside of its local area network.

1. 3D modeling software

If you are ready to create from scratch, you will have to learn special 3D modeling software. Many of them, especially professional computer-aided design systems, can be expensive investments, but on the other hand, there are plenty of quite capable and at the same time free offers on the market.

Tinkercad

Tinkercad is a browser-based application from Autodesk that is great for no-experience users, even kids, because of its simplicity. In this program, 3D models are built on the basis of basic blocks - simple geometric shapes that are joined together and then "filed" to the finished look. You can also convert 2D vector images into 3D models. Of course, you have to pay for simplicity - in the case of Tinkercad, rather primitive functionality that makes it difficult to create truly complex models. But such a task is not worth it: having gained basic skills on Tinkercad, you can always move on to more complex and more capable programs on our list. nine0003

Official website

ZBrushCoreMini

ZBrushCoreMini is primarily a 3D sculpting tool, especially popular among those who create human and animal figures, computer game characters, comics, and the like. This software is mainly aimed at beginners and users with moderate experience, but at the same time, it is full of impressive features that make the work easier. For example, dynamic tessellation algorithms constantly analyze the surface of the working model and automatically add polygons so that detail is not violated. nine0003

ZbrushCoreMini is offered free of charge and is positioned as an entry-level program for learning and gradually moving to more capable and complex options - ZBrush and ZbrushCore.

Official website

3D Builder

This program was developed by Microsoft and was included with Windows 10 for some time, although now it needs to be downloaded and installed separately. 3D Builder allows you to edit models in STL, OBJ, and 3MF formats, as well as create models from scratch. In this regard, the program is quite primitive, but it is simple and understandable even for novice modelers. nine0003

One of the interesting features of 3D Builder is the ability to simplify meshes by reducing the number of polygons, file weight and processing time in the slicer - useful in cases where the original designer obviously went too far with polygons. Additionally, you can import models from the library and even use Kinect sensors to 3D scan and import models of physical objects.

Official website

SketchUp

SketchUp is a web application with a great combination of simplicity and functionality. The user-friendly interface is intuitive and greatly facilitates learning, and the set of tools is quite diverse even for advanced users - hence the wide popularity of this program. nine0003

The free version was formerly called SketchUp Make, but is now simply called SketchUp Free. It includes everything you need for 3D modeling for 3D printing, just don't forget to download the module for exporting STL files - it's also free. The kit comes with 10 GB of storage for projects in the cloud and access to the 3D Warehouse, a repository with open source user-generated content.

2. Editing and repairing STL files

If you find an interesting 3D model on the Internet, this does not mean that it can be immediately sent to a 3D printer. Many models are created for completely different needs, such as animations or video games, and in principle are not intended for 3D printing. But there is a solution: before processing such models into G-code, they must first be repaired so that the slicer can do its job well. The following programs on our list will help you cope with the repair. nine0003

Meshmixer

Meshmixer is an advanced and free program from Autodesk that allows you to view and check 3D models for errors in polygonal meshes that can ruin 3D printing. If such problems are detected, the program can automatically repair meshes. One example of an application is finishing 3D scans to a state suitable for 3D printing.

Additional functionality includes mesh blending, 3D sculpting, surface writing, cavity creation, support branching, mesh smoothing, and more. nine0003

3. Slicers

After receiving a 3D model, it must be converted into machine code - a series of commands understandable to CNC machines, including 3D printers. Slicers are responsible for this task - programs that accept digital models (usually in the form of files with STL, OBJ or 3MF extensions), analyze their structure, and then compile lists of actions for 3D printers, called G-code (Gcode). Such lists contain all the information necessary for the equipment: to what temperature to warm up the extruders and tables, whether to use airflow, along what trajectory and at what pace to lay the plastic. nine0003

Cura

Cura is a slicer from the Dutch company Ultimaker, designed primarily for proprietary 3D printers, but open source and compatible with most other FDM/FFF systems. The program is easily customizable with various plugins. Since this is a very popular program, the chances are that it already has a profile with optimal settings for your 3D printer. If not, then nothing prevents you from creating a profile manually or using profiles prepared by other users. nine0003

The program has several levels of difficulty depending on the level of training - basic, advanced, expert and complete. The higher the level, the more access to customizable options. At a basic level, the program takes the bulk of the work on itself, helping inexperienced users.

Cura is constantly being developed and improved through regular updates and is also offered free of charge, although a paid version of Cura Enterprise is available to professional users with licensed plug-ins from the Ultimaker Marketplace, technical support and additional security measures. nine0003

In addition to converting 3D models to G-code, Cura can also take on the role of a control program, but this will require a constant connection between the 3D printer and the computer throughout the 3D printing. Professionals appreciate another feature of Cura - seamless integration with professional computer-aided design systems such as SolidWorks and Siemens NX.

In general, Сura is suitable even for novice users, especially since a huge number of training videos and step-by-step guides are available for this program, both from developers and enthusiasts. nine0003

PrusaSlicer

3D printer manufacturer Prusa Research, under the leadership of the legendary Czech engineer Josef Prusa, whose designs are copied and refined around the world, has developed its own open source software based on the Slic3r slicer. PrusaSlicer quickly gained popularity as it not only retains the original program's extensive customizations, but also adds a number of useful features not found in Slic3r. nine0003

A redesigned interface, support for Original Prusa branded 3D printers, and profiles with settings to work with many common polymers are just some of the improvements. Additionally, algorithms for generating support structures have been improved, support for multimaterial 3D printing and the ability to dynamically adjust the layer thickness have been added.

PrusaSlicer can process models not only for FDM 3D printers, but also for stereolithographic systems printing with photopolymers. As with Cura, the user can select a difficulty level with appropriate access to fine-tuning. nine0003

Official website

ideaMaker

Raise3D's slicer is optimized for branded additive hardware in the same way that PrusaSlicer is optimized for Original Prusa 3D printers, and Cura is optimized for Ultimaker 3D printers, but this does not mean that it cannot be use with third party systems. The organization of workflows and the interface is somewhat more complicated than in Cura and PrusaSlicer, but on the other hand, ideaMaker allows you to set up individual layers and apply textures for product customization. nine0003

ideaMaker users can connect to the cloud platform and access hundreds of 3D printer profiles and materials created by other operators, or create their own library of settings.

Add the ability to customize support structures, split models for more efficient 3D printing of large parts, integrated mesh repair tools, and OctoPrint compatibility, and you have a flexible, versatile program to suit the needs of most 3D printers. nine0003

Official website

ChiTuBox Basic

This is a specialized slicer for those who use stereolithographic 3D printers that print with photopolymer resins. Most budget LCD masked stereolithography (MSLA) 3D printers rely on motherboards and firmware from ChiTu Systems, which also developed this software.

Users gain control over technology-specific parameters such as layer exposure time, as well as access to predefined profiles with settings for many popular 3D printers. The slicer takes into account such moments as the orientation of the model and the automatic construction of support structures with the possibility of manual optimization. nine0003

Official website

Lychee Slicer

A program from the independent Franco-Belgian team Mango 3D, not associated with 3D printer manufacturers, but with support for many popular stereolithographic 3D printers, including those from Elegoo, Anycubic, Phrozen and Creality.

One of the features of this program is the high level of automation. If you wish, you can simply click on the "magic" button (it's called Magic), and the slicer will do everything by itself: it will orient the model on the platform, generate supports, and so on. Although, here you are lucky: the results are not always optimal, but usually adequate for relatively simple models. Otherwise, everything can be configured manually. nine0003

The program is offered in free and paid versions. The functionality of the free version is slightly reduced, but it has everything you need.

Kiri:Moto

Browser solution for those who lack computing power. Kiri:Moto can prepare 3D models for both 3D printing and laser engraving or milling. The settings are somewhat more primitive than in locally installed slicers, but are sufficient for most users. nine0003

Official website

IceSL

IceSL is a combination software that combines slicing with 3D modeling. In the left window, you can edit 3D models using scripts in the Lua language, which makes it possible to perform parametric modeling. On the right side, the 3D printing settings are displayed. For beginners, pre-configured settings are available, while experienced users can take advantage of features such as specific adjustment of parameters for individual layers with automatic gradation of intermediate areas. For example, this allows you to gradually reduce or, conversely, increase the filling density of the product as it is built, or gradually change the thickness of the layers. nine0003

4. Control programs

Control programs are designed for exactly this - managing workflows during 3D printing. Although you can insert a G-code drive into almost any 3D printer and press the start button, this is not always convenient, especially when you have to work with several 3D printers at the same time, and even more so when you do it remotely. This is where control programs come to the rescue. In addition, some of them offer additional functionality, including slicing and even editing 3D models. nine0003

OctoPrint

A web-based appliance that requires connection to a 3D printer via a microcomputer such as a Raspberry Pi equipped with a Wi-Fi module. This system allows you to control 3D printers remotely. OctoPrint accepts G-code from almost any slicer and provides the ability to visualize - view files before and during 3D printing. Alternatively, STL files can be loaded and processed directly in OctoPrint.

OctoPrint not only provides all the necessary tools for remote management, but also allows you to track the work in progress using notifications via various instant messengers. nine0003

This is a completely free, open source program with many plug-ins created by enthusiasts and available on the official website.

Official website

MatterControl

MatterHackers offers its own control program, slicer and 3D editor in one package. MatterControl allows you to directly control and observe 3D printing, slice, export G-code to SD cards for offline printing, and even create 3D models from scratch. The 3D printer will need a Wi-Fi or USB connection to run MatterControl. nine0003

The interface is well structured: on the left side there is a file browser and a library of simple geometric shapes. Interestingly, these shapes can be dragged into the 3D model and used as support structures.

Basic functionality is available in the free basic version, advanced users can pay to upgrade to MatterControl Pro.

Official website

AstroPrint

AstroPrint is a cloud-based management platform that allows you to remotely monitor and control multiple 3D printers simultaneously, store files, convert 3D models to G-code, and track workflow statistics. The functionality ranges from basic in the free version to advanced with different levels of paid subscriptions. nine0003

The 3D printer will require a Wi-Fi module to fully work with AstroPrint. In conjunction with the Raspberry Pi, the system is similar in functionality to OctoPrint: you can process models and send the finished code to a 3D printer via a web interface without the need for additional software. Another plus is integration with popular repositories of 3D models Thingiverse and MyMiniFactory, as well as 3D editors 3D Slash and Leopoly.

5. Programs for visualizing G-code

What if you find an old file with a G-code, but you have no idea what it is and why - maybe garbage, or maybe an excellent, but long-forgotten model without a clear marking in the file name? The programs in this section will help you visualize the contents of such files.

UVTools

This program combines file browsing with layer editing and even model repair for stereolithographic 3D printing. The program can also be used as a plug-in for PrusaSlicer, adding support for third-party photopolymer 3D printers - although PrusaSlicer is open source, support for stereolithographic systems is still limited to branded equipment. At the same time, UVTools allows you to print calibration samples to check the exposure time and other parameters, which can be useful, for example, when working with new photopolymers that have not yet been tested. nine0003

Official website

WebPrinter

A simple browser tool for quick G-code preview, developed by the same team that created the IceSL slicer and 3D editor. The application works very simply: follow the link, upload the file with the G-code and see how the 3D printer will grow the model according to the commands provided. Unfortunately, the functionality is limited: for example, the application does not provide information about temperature settings. On the other hand, you can quickly figure out what kind of model is hidden in a file with an incomprehensible name. nine0003

Official website

Gcode Analyzer

An old but still very capable and popular G-code analysis web application. The 3D simulation doesn't work very well, but the 2D and G-code previews work great. In 2D mode, you can conveniently view individual layers, moving from layer to layer and following the construction path step by step using two sliders. G-code viewer displays a complete list of commands, allowing you to see what a particular line of code is doing. nine0003

  • To summarize

The whole cycle of creating a part on a 3D printer can be fit into three stages: Creating / finding a model, cutting a model in a slicer, printing on a 3D printer. Each stage is tied to its own program. Models are created in special programs, then in the slicer the model is “cut” into steps that the printer will sequentially execute. The resulting list of steps (commands) is either placed on a memory card and run from the printer itself, or sent to the printer via a wired/wireless connection. As a result of all these actions, we get the product. Therefore, looking for a “3D printer program” is wrong: you need to look for a modeling program and a slicer. nine0003

3D modeling software

Programs for 3D modeling are divided into two large groups:

Obviously, when creating a drawing, an engineer needs precise tools: a ruler, pencil, compass, etc. But the artist needs more free tools: brushes, pastels, palettes and others. Programs are divided according to the same principle: in engineering programs, there are all the tools that allow you to accurately specify the characteristics of each element of the part, and in art programs, tools are created to give smoother shapes so that the model looks as natural as possible. Of course, in art programs it is possible to model technical products, but this is comparable to drawing a drawing with pastel: it is inconvenient, difficult and inaccurate. Therefore, it is very important to determine why you need a simulation program. nine0003

Tip: It is best to learn one or two programs at a professional level, as this will allow you to create complex models. But you should also know the basics in other programs, since a large circle of knowledge allows you to more flexibly choose the approach to creating models.

File types for 3D printing

To begin with, it is worth understanding what types of files are involved in the manufacturing process of the part. The first step is to create a model. It can be saved in the format of the program itself (for example, KOMPAS-3D files have the .m3d extension, while 3ds Max has the .MAX file extension). Such files can only be opened in the programs in which they were created. But we need a universal format - STL. All programs can save models in this format. It stores the polygons that create the model. nine0003

All files are divided into 3 categories:

• Files that store polygonal information (STL, OBJ, etc. ). They are analogues of a raster image. It is possible to increase the quality of 3D models in this format only by smoothing, but in this case small details will be lost, and the file weight will increase greatly.

• Files that store the steps for creating a part (STEP, STP, etc.). Here you can draw an analogy with vector images. Each element is specified either using simple dot connections (for example, as in a cube or pyramid), or using formulas (any curved, rounded objects). Models in this format can be scaled without loss of quality, while maintaining a relatively small file size. nine0003

• Utility files that store steps for a 3D printer (GCODE, GCOD). These files store the commands that the printer executes and, in some cases, comments (for example, with what settings the model was cut). Some slicers can simulate the movements of the printer, thereby rendering the model, but it is impossible to convert a file from this format to a full-fledged model.

nine0363 Be careful! If ​​you are not sure that the GCODE file is intended for your printer, then you should not print it, because the print area for each printer is different. On third-party firmware there is no limit on the maximum travel distance, some third-party software commands may lead to incorrect operation of the control board. If the printer tries to move the print head out of the printable area many times, then it can harm itself! nine0364
