3D printing also known as additive manufacturing, it is that process through which solid objects can be built from digital files. This can be achieved with using various 3D printing techniques. Most of these techniques involve the creation of an object by laying down thin layers successively. Well anyways, the process of 3D printing and the various techniques involved is out of scope of this article. In this article we take you through all the 6 steps that are to be undergone for printing a 3D object.

Slicers are the final piece of the 3D Printing puzzle. Slicing software turns the 3D model file, normally an.STL or.OBJ, into a usable set of instructions for your printer to plot in 3D space. 3D printing won't yet replace carpentry or masonry, but it's getting closer. Plastic filament embedded with wood shavings or chalk produces a final product that resembles wood or concrete-like stone. 3D printed items can be quite sturdy when designed well. You can use your creations yourself or gift them to someone. We have compiled a list of the most useful things to 3D print in various categories. This list can be used by students, teachers, 3d print businesses, makerspace organizers, and 3d printing.
Here Are The Steps Involved in 3D Printing:
#1 CAD File Development
In order to produce a 3D object you first have to have its virtual design. This is to be done using the Computer Aided Design (CAD) software. Through this the exact dimensions of the objects considered and simulated to see how the object will behave under various conditions.
#2 CAD File Conversions
Once the CAD file is developed, the next thing one has to consider is converting it into specific file formats. The file formats are specified based on the technology of printing being employed by that particular 3D printer. For instance, the CAD file has to be converted into a STL (standard tessellation language) if the printer is based on the stereolithography technique.
#3 STL File Manipulation
Now that the STL format file is ready with you, all your computer now needs is a 3D printer which can print using the stereolithography technique. But before this, users will have to set the orientation and size of the object to be printed. This is similar to the case of a 2D printer.
#4 Preparing The Printer
Now that everything about the digital file is ready, you need to make sure the 3D printer is ready as well. This means installing properly the polymers, binders and other material which are necessary to perform a print operation. Once all such requirements are met, you are almost ready to print.
#5 The Building Up
Once the process has started, it is now all about patience. These printers aren't as faster as the 2D printers. How to download imovie for free on iphone. Based on the complexity of the object to be printed, the span of printing varies. Simply all that one has to do is wait and perform random checks to make sure everything is being done flawlessly.
Since the entire construction of the object is in form of very thin layers, it definitely is going to take some time.
#6 Post Processing Stuff
Once the entire process is done and the object is ready, make sure you handle it carefully. Any actions in haste could prove to be costly. So right from putting on some gloves to bring the object out of the printer to brushing off any residual powder, everything is to be handled carefully.
And that's it! If your CAD file is perfect and the post processing part is well executed, then you'll have it; your first 3D printed object.

Finding the right 3D modeling software for 3D printing is tough. That's why we want to give you a complete overview about the best and most popular free 3D modeling software in this blog post.
Classifying and benchmarking different 3D design program is a very complicated matter as everyone has different preferences and applications for 3D printing in mind. Our 3D modeling & 3D printing community here at i.materialise uses tons of different software to get the job done: from free online 3D design apps to high-end professional software.
There are several reasons why it's so difficult to find ‘the best' 3D modeling software:
- There are tons of 3D modeling programs out there. It isn't a case of one software dominating the market, which can make choosing the right one quite complicated and confusing.
- 3D modeling software works in very different ways. One software might be quite intuitive for some people, but really complicated for others. There is no one-sizes-fits-all-approach.
- Users typically have very strong opinions that the software they are using is the best one. So everyone seems to have a different opinion on which software is the most suitable for creating a 3D file.
- Professional 3D modeling software often comes at a high price. Many people don't want to take the risk of purchasing high-end software without having tried free software first.
But we're going to take it step by step here. I will briefly describe the most popular free programs out there. I will also try to point out how you can progress to more sophisticated programs later.
I have tried to put them into different categories based on the style of 3D modeling that is predominant for each software. While you have to sculpt in some, you merge geometric elements in others.
Solid Modeling/Box Modeling:
If you are just starting and have never created a 3D model before, TinkerCADis absolutely indispensable. It's an easy beginner-friendly app with a LEGO-approach. Basically you will combine different geometrical shapes together, in order to create new objects. TinkerCAD is great if you like geometrical designs and a geometrical way of thinking. It's very hard to create organic objects with the interface, however (like people, animals, etc.).
We have a tutorial about how to create your first 3D print in TinkerCad here. Take a look at it to get a better feel for this software.
This ‘saw wrench' was designed by Pekka Salokannel in Tinkercad.
If you reach the limits of TinkerCAD and you like the logic behind this app, you can continue to more sophisticated software like Fusion 360. Fusion 360 was also developed by Autodesk, the company behind TinkerCAD. This powerful program is now available for free for students, enthusiasts, hobbyists, and startups. It combines the professional capabilities of a high-end CAD program with an user-friendly interface and workflow. That's why Fusion 360 is such a popular program among industrial designers.
Parametric Design/Procedural Modeling:
Parametric 3D modeling software allows you to easily navigate and modify your 3D model by browsing back into the model history and changing its individual elements. Typically this software is at its most powerful if you want to focus on precision. However, you won't have much ‘free-style' design freedom.
FreeCAD is a free software that allows you to create precise geometric designs, such as technical parts, replacement parts, gadgets, cases, scale models etc. You can learn the basics in our beginner-friendly FreeCAD tutorial.
Typical workflow in FreeCAD: From a rough sketch to a precise 3D model.
If you would rather like to code your 3D model, OpenSCAD might be for you. This software uses programming language to create 3D objects. If you want to learn how to code your design, take a look at our OpenSCAD tutorial.

If you enjoy FreeCAD you might want to switch to the professional 3D modeling programs Autodesk 3DS Max or Autodesk Maya in the future.
Digital Sculpting:
Digital sculpting is the way to go if you want to create organic designs: people, animals or creatures. This is where your mouse movements matter the most, and mechanical precision matters the least.
Meshmixeris a powerful, free software that lets you sculpt digitally and mash different 3D models together. Mold and refine surfaces in real-time like virtual clay! Once again, we have the right tutorial for you to get started.
The ‘Piguin' by Bert De Niel was created in Meshmixer and 3D printed in our multicolor material.
Sculptris provides an excellent gateway into the exciting world of 3D sculpting. Its features are easy to learn, even for someone with no experience in digital art. Yet the 3D sculpting software is robust enough to create base models that can then be refined in other, more sophisticated applications later.
If this kind of modeling is your cup of tea, you will probably want to switch to the professional premium software ZBrush later on or you can also try one of these 3D scultping programs.

Polygon Modeling/Contour Modeling:
In Polygon Modeling, your 3D object is basically a mesh based on vertices, edges, and faces. This allows for precisely editing parts of your object. By changing the coordinates of one or several vertices, you can change the shape of the model. That makes this way of modeling very powerful but also more difficult to start with.
The most popular free software in this section is called Blender. However, it's also the most difficult program mentioned in this blog post. The power of design freedom comes with a steep learning curve. That's why we published video tutorials on how to get started as well as on how to turn your Blender model into a 3D print.
A premium software that is somewhat similar to Blender is Modo, which also comes in a free 30-day trial version.
Curve & Line Modeling:
This is the process where models are based on drawing lines or curves in a 3D space. By joining these lines or curves together you will define the surface of your object. This manual way of designing allows designers to create precise objects.
SketchUpis a software that architects, interior designers, and scale modelers love. SketchUp is mainly based on lines – 3D models will be edgy as a result. The first steps are fairly easy, but making a printable model can be challenging sometimes. Take a look at our tutorials to learn how to create your first SketchUp 3D model and how to make it 3D printable.
Once you master this program, you might switch from SketchUp Make (free version) to the premium SketchUp Pro version.
Scale Modeler Guido Mandorf creates his tram models mostly in SketchUp.
For curve modeling Moment of Inspirationand Rhinoceros (Rhino 3D) are popular choices. Unlike SketchUp, you don't focus on lines but rather on curves. This allows for great round shapes in product designs. You can check out our video tutorial to get a better understanding of Rhino. While Rhino doesn't come for free, it offers a free 90-day trial. Enough time to test it.
