Modeling for 3D Printing: Tips by Jeremy Ortiz

_We invited designer and digital sculptor Jeremy Ortiz (@zbrushninja) to share his top tips on modeling for the Form 1+ 3D printer.

I come from a traditional sculpting background using clay and wax. For me, using ZBrush simulates sculpting in these traditional materials so well that nearly of my traditional skills and techniques were directly translated into the digital medium. I was instantly hooked on this new medium of digital clay.

As a digital designer, I knew if I wanted to be able to take my ZBrush sculptures into the real world, I needed a high resolution printer that could capture the fine details of my sculpts so I could use my prints as masters for molding or directly as one-off production prototypes. The Form 1+ is the only desktop 3D printer that offers a level of detail that could effectively and accurately reproduce my sculptures with a superior level of detail and quality that was on par with industrial stereolithography printers. All of that with a cost that was within my budget.


Dragon Bust by Jeremy Ortiz, 3D printed in Grey Resin on the Form 1 +.

It wasn’t until I was holding a 20mm tall dragon head print in my hand, with details so fine that it made pencil points, X-acto blades and fingerprints seems huge that it hit me just how powerful of a tool I had in my possession.

Here are 7 tips I have found helpful when designing and modeling for 3D prints. I personally use ZBrush and Maya for my work, but these tips should work on most 3D modeling software.

1. Keep Your Parts Manifold
For modelers coming from animation, illustration, or gaming backgrounds, one important thing to remember is that your 3D prints must be composed of watertight manifold volume parts. Always check your model for artifacts, loose faces or unwelding edges and verts.

That means:
- No one dimensional planes,shells or extruded edges
- No double sided faces
- No self intersecting faces
- No open faced holes
- No unwelded verts or edges

PreForm, Formlabs’ free downloadable 3D printing software, has automatic tools that ensures your model is watertight.

2. Multi-object Prints
Does my part need to be one continuous mesh? This is a question that many new modelers have when creating for 3D printing. The simple answer is that a continuous mesh is not required. You can design prints from overlapping or intersecting objects so long as all components involved are manifold parts.

3. Know Your Build Area
When designing your part, keep in mind your build area. However, your printer’s build volume does not have to limit the size of your final model. Be creative! Clever layout in your build area can help you get larger prints. For instance, the diagonal space from top to bottom in your build area will give you the longest build size of your printer.

4. Small prints and exaggerated details
When sculpting small parts, it’s often very helpful to slightly exaggerate details. This means making your surface details with slightly deeper cuts and more pronounced surface texture. If possible, making slender parts slightly thicker will help ensure that they will print clean.

5. Save Material
Making your model hollow using shell and boolean functions available in your modeling software will save you resin material. Be sure to make a large enough “vent hole” that connects to your hollowed area to the outside of your model this will allow uncured material to flow out.

6. Clean Up Well
After your print is finished you have to soak your finished print in IPA for 12-15 minutes. I find that towards the end of the soak you can give your part a gentle rubdown with your gloved hand to help break down and remove any resin stuck to the surface of your print. Using a soft brush also helps to reach area that you can’t reach with your hand, this added step this helps get a quality finish to your print.

7. Remove Supports Carefully
Take your time when removing your support material. Rushing this process could ruin an otherwise flawless print. Using an X-acto knife to score a line at the connection point will give a cleaner break. Give thicker supports a gentle wiggle, don’t pull or use excessive force.

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

What is the best CAD software to design 3D prints?

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.

Rules for 3D modeling for 3D printing

It is known that a prerequisite for 3D printing is the presence of a 3D model, according to which the printer will grow a three-dimensional object. But, even after simulating an object, you should not assume with absolute certainty that the job is done, and soon the printer will give you the finished product. The fact is that not all models are suitable for 3D printing. There are certain requirements for the dimensions, thicknesses and design of models - and these requirements vary depending on the material used and the printer. In addition to these individual characteristics, there are general requirements that distinguish print models from other 3D models. And now we will talk in more detail about how to prepare a model for 3D printing. nine0003

First of all, you need to remember that STL files (for one-color models) and WRL (for color plaster 3D printing) are suitable for 3D printing. Almost all 3D modeling programs allow you to export models to STL, so this should not be a problem. You should also take into account that for online download on our website, files no larger than 50 MB each are accepted, as well as an extended list of formats that are automatically exported to STL: STP, STEP, OFF, OBJ, PLY and directly STL. If the file size is more than 50 MB, then you need to send the model to our email address: [email protected]. By the way, one of the easiest ways to reduce the volume of the model and the file size is to create hollow 3D models, we already wrote about how this works in our blog. nine0003

Before you start creating a model for 3D printing, it is important to understand what material you want to print the product from. Each material has its own individual characteristics for 3D modeling - maximum and minimum model dimensions, wall thicknesses, distance between moving parts, etc. You can learn more about the requirements for a particular material in the appropriate section on our website.

If you use the online model upload on our website, it will automatically check for standard 3D modeling errors. Models are checked instantly, and if errors that prevent 3D printing were not found, then immediately after uploading the model will appear in your personal account in the "My Models" section. If the model did not pass the test, then you will see a notification that the file cannot be loaded, then you will need to check and refine the model again. nine0003

What are the most common errors encountered when modeling for 3D printing?

  1. Inverted normals - incorrectly oriented normals. Normals should always point outward, they define the boundaries of the object and allow the 3D printer software to understand which is the inside and which is the outside of the model. If at least one of the normals is directed in the opposite direction and contradicts the other normal, then this causes a failure in 3D printing, since the printer cannot distinguish between the front and back sides of the object. nine0018
  2. Non-manifold geometry - Non-manifold 3D model is a prerequisite for 3D printing. The essence of this concept is that each edge of a 3D model must have exactly two faces.

The following errors are usually included in this concept:

o Mesh with holes - "unclosed" mesh problem. Remember the basic rule of 3D modeling: your model must be "watertight" or "airtight". If a hole is formed, it means that some edge is missing one face, therefore the model is not manifold, and therefore not suitable for 3D printing. nine0003

o Presence of internal polygons. There must be no faces inside the model, for example inside walls.

o Common ribs. An error occurs when more than two polygons are attached to the same edge. Each edge in your 3D model should connect only two adjacent faces.

o Matching edges. Occurs when two separate edges are created at the same location and are not connected, such edges must be merged into one common edge. nine0003

o Polygon overlap. Occurs when a polygon is created on top of an existing one. Intersecting edges can confuse a slicer - a program that translates a 3D model layer by layer into a control code for a 3D printer.

o Zero polygon thickness. To avoid this error, make sure that each polygon has the specified thickness.

How can standard errors in 3D modeling be corrected?

To do this, it is enough to use the Netfabb program, which, with more than 95% chance to correct all errors. You can download Netfabb here or use the online version of the program.

      • Programs for cutting 3D models (slicers)
        • Free slicers
        • Paid slicers
      • 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 forms 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.


    nine0099 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! nine0100

    If the files are in the same category, then they can be easily converted from one format to another with almost no data loss. The formats indicated in brackets are a kind of “transits”. For example, Inventor has its own file format - itp, and Fusion 360 has its own - f3d. But if you save the file in Inventor in the generic STEP format, you can open it in any engineering program and then save it in that program's format.

    Free programs

    Usually, free programs are either limited in functionality or created by enthusiasts, which is why they have a very crooked interface and a lot of errors. But their functionality is enough to create simple models, and in some cases, such programs can completely replace paid software.

    Tinkercad

    In essence, this is not even a program, but a website, that is, it does not need to be installed on a computer and it opens from any device that has Internet access. But this is its main disadvantage - without Internet access, you will not be able to download any model for yourself, because each project is initially saved in the cloud. You also need to register to use this site. Initially, the site was created for children, so each tool is intuitive. The program is suitable for modeling simple products: gaskets, bushings, adapters, covers, boxes, etc. nine0003

    Pros:

    Cons:

    • Inability to work without the Internet

    • Each individual project needs to be downloaded

    • Limited number of tools

    FreeCAD

    This program is designed to create technical products: fasteners, bushings, hinges and more. Since this is an open source project, it is distributed free of charge. At the same time, it has all the necessary functionality for opening and editing files with the .step extension - a universal format for all engineering programs. It is also worth noting the ability to add addons - special subroutines that allow you to perform any actions in a fully automatic mode. For example, there is an addon that makes it easier to create various gears. In this program, you can create more complex products: mechanisms, gearboxes, hinges, etc. nine0003

    Pros:

    Cons:

    OpenSCAD

    This CAD is closer to programming languages ​​than to modeling: each object or any action is specified as a code. This allows you to create universal models. For example, a coin sorter: once you write the “model code”, you can create a huge number of variants of this model for different countries, changing just a few parameters. This program, like the previous one, is an open source project, as a result of which it is regularly updated. nine0003

    Pros:

    • Works on weak PCs

    • Ease of creating universal models

    • Easy to learn if you have programming experience

    Cons:

    • No Russian interface nine0003

    • Is a programming language

    • Difficult to create curvilinear geometry

    Meshmixer

    Art program for entry-level 3D modeling. There are simple tools for processing STL files and functions for recovering “broken” files. Using Meshmixer, you can conveniently cut the model into several parts, as it is possible to set the size of the print area of ​​your printer. And one of the most useful tools is the installation of tree supports. This function has already appeared in many slicers, but it is in meshmixer that they can be flexibly configured and installed manually. Despite the many tools, this program is rather auxiliary, as there are more suitable programs for creating a model from scratch. nine0003

    Pros:

    Cons:

    • Limited functionality for creating 3D models

    • Lack of Russian interface

    • Some operations require a powerful PC

    Blender

    A completely free program with huge possibilities not only for creating models, but also for animation, rendering, simulations and much more. It is mainly used by multipliers, but due to the large number of extensions, this program covers a huge range of tasks. At first glance, Blender may seem too complicated, but everyone can master the basic functionality. Also worth noting are constant updates that improve performance and add new tools. A large community of people working in this program and developing it will help with the solution of many problems. nine0003

    Paid 3D software

    This category includes programs for professionals and enterprises, as well as their simplified versions for home use. Many companies have begun releasing a product at a low cost for home use, although initially the designs were intended only for enterprises and were priced accordingly. The common advantage of these programs is great functionality and constant support. For example, Autodesk Inventor was first released back in 1999 and is updated annually. Next, we will look at the most popular of them.

    Fusion 360

    The new product from Autodesk tried to combine several tasks at once: modeling, simulation and rendering. In many ways, it adopted the functionality of the previously mentioned Inventor, but supplemented it with a simple interface: many tools are similar to those that can be used in the previously mentioned Tinkercad. You can also edit STL files in it, albeit with a limited set of tools. nine0003

    The main feature of this program is cloud data processing, such as simulations and renders. At the same time, almost all functions can be performed offline using the power of a PC. To process tasks in the cloud, you need to buy additional tokens, but when creating models, they are not necessary. It is worth considering that despite the presence of a native file format (f3d), all files are initially stored on Autodesk servers, and then they can be saved to your computer. nine0003

    There is a version for schools and universities, but obtaining such a license requires the educational institution to register and issue you a personal license.

    Pros:

    Cons:

    Price: from 7,123₽ to 25,721₽ for 1 year

    Netfabb

    The program is designed to prepare the model before slicing. In many ways, it is similar to meshmixer, but it does not have the tools to create a model from scratch. Merging several models in STL format can be called a distinctive function, but the most important tool is the “repair” of models. That is why everyone should install this program, even if you have another model editor or model repair built into the slicer. Also in Netfabb it is very convenient to cut the model into several parts for printing separately. At the moment, the Netfabb functionality is built into Fusion 360 and is not officially available separately, but can be found on third-party resources as a separate program. nine0003

    Pros:

    • Great functionality for repairing the model

    • Convenient cutting into pieces

    • Easy to learn all the necessary tools

    Cons:

    Price: from 18 024₽ for 1 month

    KOMPAS-3D

    A professional program created by Russian developers for Russian enterprises. It has a huge functionality, but at the same time, each function has a description, and the main tools have explanatory animations, a huge database of standards and GOSTs is built in. The program is free for all students and does not require verification of documents. There is also a paid version of KOMPAS-3D HOME, which, although intended only for home use, retains all the functionality of the “professional” version. Because of this, and also because of the low price, this CAD system is the best choice as the first professional program for creating complex 3D models. nine0003

    Pros:

    • Completely Russian interface

    • A large number of tools

    • Availability of a free student version

    • Very low price

    Cons: nine0003

    Price: from 1 490₽ for 1 year

    SolidWorks

    One of the oldest programs on the market that has become a standard. If you learn how to work in SolidWorks, then you can work in any CAD. It has a relatively simple interface, an average number of tools that are enough even for professionals, but since the program is designed for production, many functions will only interfere with work. It should be noted that this program is available in Russian, and this is one of the reasons for the prevalence of this program in Russia. nine0003

    Pros:

    • Easy to learn

    • The presence of the Russian interface

    • Large community of people using SolidWorks

    • Widespread in Russia

    Cons:

    Price: from 8,431₽ to 292,560₽ for 1 year

    Inventor

    The main program at many enterprises, but due to the simplicity of the interface and the presence of the Russian language, it is easy to learn. In many ways, it is similar to SolidWorks, both in functionality and in purpose. The main distinguishing feature of this program is a large number of high-quality video tutorials and text courses. It is studied at many universities both around the world and in Russia. nine0003

    Pros:

    • Prevalence among the Russian community

    • Lots of learning materials

    • Intuitive interface

    • Availability of student version

    nine0098 Cons:

    Price: from 106 860₽ for 1 year

    SelfCAD

    It is the simplest program for technical modeling. As easy to learn as Tinkercad, but not for kids, but for professional 3D printing. This program is not CAD, so there is no editing history, which allows, for example, to change sketches without entering edit mode.

    You can download this program for free, but this version will have limited functionality. There are also paid versions with monthly payment or a one-time purchase forever. Only paid versions have a simple slicer, but its functionality is extremely limited. nine0003

    Pros:

    Cons:

    • Small functionality

    • Big cost

    Price: from 1160₽ ($14.99) for 1 month

    3ds Max

    The program is designed to create 3D models and render images. It has great functionality, but it is extremely difficult to learn due to the lack of the Russian language and a complex interface. This is due to the fact that 3ds Max was originally developed for 3D animation and video game studios. It was to create a simple and free analogue that the previously mentioned Blender was created. Due to the above reasons, this program is not suitable for creating 3D models for subsequent printing on a 3D printer, but nothing prevents you from doing this. nine0003

    3D cutting software (slicers)

    Having any model in STL format, you cannot immediately place it in the printer and start printing, because the printer only executes commands, and these commands form a slicer. According to the etymology of the word, one can understand that the program cuts the model into layers, or rather into separate commands. But the number of cutting options for one model is almost endless. In this regard, a large number of programs have appeared that allow you to fully customize the operation of the slicer, or rather, how it will split the model into separate commands. The slicer itself consists of two parts: the core and the shell. The slicer core performs slicing based on the specified parameters, and the shell allows you to set these parameters and visually evaluate the slicing result before sending the model to print. In addition, many slicers have built-in functionality for direct access to the printer, which allows you to manually control the printer and carry out its settings and diagnostics. Next, we will consider the most popular slicers, which have their positive and negative sides. nine0003

    Free slicers

    The availability of free slicers is due to the fact that without them the printer becomes a useless machine that can only heat coffee and play a melody with the help of motors. Therefore, many companies that create 3D printers supply slicers with them, while laying them out in the public domain. Often these are large companies such as Ultimaker, CraftUnique, Prusa, etc.

    Ultimaker Cura

    It was originally created only for Ultimaker 3D printers, but soon became an open-source project. Now in its library of profiles you can find a huge number of printers from various manufacturers. Uses its own core Cura, which has many settings and functions: tree support, wireframe printing, color printing, etc. nine0003

    Frequent updates bring innovations and even more profiles for various 3D printers. It is a standard choice for beginners, as it has two control modes: simple and professional. Recently, support for add-ons has appeared that allows you to save backup copies of settings, repair the model directly in the slicer, integrate various programs for 3D modeling, and much more.

    It is also possible to control the printer by sending commands directly from the computer. But there is no feedback from the printer, apart from receiving information about the temperature of the nozzle and table. nine0003

    Pros:

    Cons:

    Prusa Slic3r

    Sometimes you can find other names: Slic3r Prusa Edition or Slic3r PE. Prusa decided not to reinvent the wheel, and took the open-source Slic3r project, partially reworked it and began to actively develop it. Like Cura, Prusa Slic3r has many printer profiles, but Prusa's printer profiles are the most optimized. The core of the slicer of our own design, while the number of settings is less than that of the same Cura. nine0003

    A distinctive feature is the flexible adjustment of the layer thickness and the support of a special extruder capable of printing 5 different plastics at once (again, produced by Prusa). The program will be extremely useful for people who have more than one 3D printer: all settings are divided into 3 tabs, each of which can be saved to separate profiles. But the printer control console disappeared completely, only the send button for printing via wire remained. In general, this program will be a reliable and convenient slicer, especially if you have a large number of printers. nine0003

    Repetier

    This slicer was created more for remote control of the printer, but it can also cut models. One of the few programs where you can choose the slicing core: Cura, Sic3r, Prusa Slic3r. The number of settings for the slicing itself is extremely small, but they are enough to cut the test cube.

    The most important plus of this slicer is the huge functionality for managing and configuring the printer. It is worth noting the convenient interface for sending commands, as well as customizable temperature graphs. This is extremely useful, for example, when tuning the PID or checking the movement of the axes. Even if you choose a different slicer, this program is handy to have in order to 3D print using GCODE from another slicer. nine0003

    Cons:

    MatterControl 2.0

    One of the few programs that combine functions for editing stl files and a slicer. You won't be able to create any serious model, but you can add text or cut out part of the model. The slicer has not so many settings, but they are enough for a beginner 3D printer. This slicer can be useful if you need to make art products with minor changes. Supports saving to the cloud. nine0003

    3DprinterOS

    This software is designed to remotely manage printers from anywhere in the world. All that is needed is to connect the printer to the computer and install this program on it. From now on, all printer management occurs through the web interface. In it, you can remotely change the model, cut it and put it on print. It is also possible to connect a camera and observe the printing process. There are very few slicing settings, some will not even be enough to calibrate the printer, not to mention serious printing. nine0003

    Carefully! It is not recommended to leave the printer unattended, especially if it is no longer new: at any time there may be a risk of fire due to wiring or mechanical problems.

    Pros:

    • Simple interface

    • Start printing from anywhere in the world

    • Ability to monitor printing nine0003

    • Availability of tools for editing the model

    Cons:

    IceSL

    It is a combination of OpenSCAD with its “modeling language” and slicer. In addition, models can be edited using a “brush”, like the one in Meshmixer. It has many small pluses that are not found in other slicers, but it is not suitable for everyday use due to an inconvenient interface and a small number of slicer functions. This program can be described in one phrase: interesting, but not recommended. nine0003

    Pros:

    Cons:

    Octoprint

    In many ways it is similar to 3DprinterOS, but is an open source project, as a result of which it has many additions. Designed for home use. It is the most popular way to remotely control a printer, and the user community is constantly growing. Therefore, it will be very easy to transfer your printer to remote control due to the large number of lessons and articles. The program itself does not have a slicer, but direct export of files from Slic3r is supported, which is already good in itself. Just like Repetier, it has an excellent printer management and monitoring console. But, unlike the aforementioned analogue, most of the functions will have to be configured manually. nine0003

    Pros:

    • Large user base

    • Lots of tutorial articles

    • Ability to create a video broadcast of the printing process

    Cons:

    Paid Slicers

    At the moment, many paid slicers are no longer used, as free ones have either caught up or overtaken them. But some of them are still unique. nine0003

    Simplify3D

    One of the first thundered paid slicers. At the time of its introduction, it was the most advanced due to the ability to change the print settings for one model at different layer heights and the functionality of printing with more than one extruder. But at the moment it has been replaced by Cura and Prusa Slic3r. Nevertheless, the convenience of setting up print settings and their number still remain the main advantage of this slicer. Also worth noting is the excellent printer management interface, second only to Repetier host. nine0003

    Another difference is the ability to manually install supports and a large number of filling patterns. Viewing models also has several features: changing the way models are displayed, viewing in section, displaying normals to planes.

    Pros:

    • Lots of print options

    • Convenient printer management interface nine0003

    • Manual installation of supports

    • Changing print settings at different heights

    • Easy print setup with two extruders

    Cons:

    Price: from 11499₽ ($149)

    Astroprint

    Many believe that this particular software is a direct competitor to 3DPrinterOS. The most important difference is user friendliness, achieved through a user-friendly interface and easy installation. The program is based on Octoprint, essentially providing only a server, a modified interface and several add-ons that allow you to fully manage the printing process while away from the printer - from finding a model, to cutting and printing. At the same time, the program positions itself as a serious business solution, so the company also provides special PCs and management consoles that make it easy to connect the printer to the system. A trial plan is available where only 2 printers can be connected, but all basic features will be available. nine0003

    Pros:

    • Easy connection and setup

    • Trial Availability

    • Interface specially designed for mobile devices

    Cons:

    Price: from 765₽ ($9.90) for 1 month nine0003

    KISSlicer

    This slicer is another representative of programs that failed to keep up with the times. Previously, its functionality was a cut above the rest, but now the same Cura has all the same settings as KISSlicer, and also adds its own. Of the useful in this program, we can note the function of joint viewing of GCODE and model.

    There were two versions: free and PRO. The only significant difference between them is that the paid version has support for printing in multiple colors. At the moment the project is dead, even the main site does not work, but the program can still be found on third-party sources. nine0003

    Pros:

    Cons:

    Price: from 3240₽ ($42)

    Summing up

    After considering all the popular programs, we can highlight the clear favorites:

    For beginners in 3D printing, Tinkercad is the best 3D modeling software because it combines simplicity with the necessary functionality. The best programs for professional-level 3D modeling are KOMPAS-3D, Fusion 360 and Blender, due to the huge number of tools and a large community that makes it easy to find lessons and guides.
