D Printing In The Automotive Industry
3D printing is also transforming the automotive industry, evolving from printing relatively simple prototypes of low production parts to 3D printing entire cars. In-car auto designs, auto parts can also be created using 3D printing. Sometimes, a scale small model is printed to gauge scale before the assembly process. This technique also helps the industry by producing rapid prototypes and reducing money and time for production. Some other automotive companies are dedicated to creating customized auto parts for special model cars. Read here more case studies about 3D printing in the automotive industry.

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.
What Is An Stl File
STL, an acronym for STereoLithography, is a file format created by 3D systems for its CAD software. Its also supported by many other software, either CAD or mesh editing tools. Its mainly used for 3D printing, rapid prototyping, and computer-aided manufacturing.
This format represents the surfaces of a model with small triangles. The more complex the structure is, the more triangles will be used to get the right model.
STL file format is one of the most commonly used file formats. Thus, you will find many 3D models using this file format when looking for a 3D file to 3D print. Sometimes, you will have to repair your STL files, so here are some tips to help you with this files repairing process.

Localizing Production Of Items
3D printing can also be used to localize production of items, resulting in a massive change to supply chains and logistics.Rather than supplying from a single factory outlet, a company will be able to establish much smaller production units all over the areas which they serve, thus minimizing transportation costs. This will be a great advantage to multinational companies that serve at a global level. Smaller batches could be created at strategically-placed locations to effectively cover all the countries while reducing the logistical expenses significantly.
The increased efficiency offered by 3D printing will also pave way for greater customization for consumers. Also, instead of outsourcing, the local production of items will bring back manufacturing to domestic soil. Although such complex economic discussions are beyond the humble authors of this book, we think that the potential for a true renaissance of manufacturing in countries such as the United States and United Kingdom is immense and all thanks to 3D printing.
Before the 3D printing technology can bring about significant changes to the manufacturing industry, it first has to establish itself as being ready for mass, mainstream manufacturing with the rates at which the technology is improving, the day may not be far when instead of buying products, people buy design blueprints and print the products using their desktop 3D printers!

Tip #1: Stylistic Variations
Meshmixer also features a list of stylistic variation to allow designers to get creative when editing meshes.
The Edit Make Solid command from the main menu creates a watertight solid from mesh surfaces by recomputing the object into a voxel representation. If we opt for Blocky mode under Solid Type with large cell size, it results in a funky voxelized model. To prevent straight overhangs that need support structures, the trick is to first rotate the object by 45 degrees over the X or Z-axis using the Edit Transform tool. Use Edit Plane Cut to make the bottom flat again.
Making good low polygonal models is an art that often requires many hours of manual design work. MeshMixer provides advanced functionality to turn even complex objects into striking low poly pieces. This can be done in two passes:
First, determine the minimum triangle size necessary to preserve detail. This removes unnecessary detail which speeds up experimentation in the second pass. Click Edit Remesh and choose Relative Density mode. Turn down the Density slider to where the geometry is still reasonably represented, with the Preserve Sharp Edges option left unchecked.
Third Choice: Iges/igs Files
This file type was created by the US Air Force and was used for exchanging CAD geometry. It was later adopted by the American National Standards Institute .
Main thing to know about this file type is its an older, unsupported specification so it will never be updated or changed. Hence, why this is the third best choice for 3D printing files.

What Would Be Something Cool To Make With A 3d Pen
If youâre looking for a smaller and more affordable option, 3D pens are a great choice to get your creativity flowing too. 3D pens are affordable, easy to manage, smaller in size, and more practical. Using a 3D pen you can easily turn things to 3D. Design and personalize cool things to 3D using your imagination and 3D pen. From making repairs by using 3D pen as an adhesive to creating pieces of artwork, 3D pens give you the flexibility to draw your ideas immediately.
If you love architecture and buildings, companies have created kits that allow people to replicate architectural structures and other cool things with a 3D pen. For boardgame lovers, you 3D print your own figurines by drawing it with your 3D pen. You can also turn your favorite cartoon show characters or movie heroes into 3D. While a 3D pen allows you to draw 2D things to 3D, their limitation tends to be the size of the project you can make. If youâre looking to 3D print a life-size chair, it may be easier to use a printer because 3D pens may not be able to create something as durable.

Stl Is The Standard File Type Used By Most Additive Manufacturing Systems
STL is a triangulated representation of a 3D CAD model .
The triangulation of a surface will cause faceting of the 3D model. The parameters used for outputting a STL will affect how much faceting occurs . You cannot build the model smoother than the STL file. If the STL is coarse and faceted the physical 3D printed model will be coarse and faceted as well. However, the smoother/ less faceted your surface is, the larger your file. 3D printing can only accept a certain file size therefore its important to find a balance between your model, its desired surface, and the 3D printing process of your choice.
When exporting to STL in your CAD package, you may see parameters for chord height, deviation, angle tolerance, poly count, or something similar. These are the parameters that affect the faceting of the STL. Weve compiled tips on exporting for the best surface: file size ratio below.

How Should You Go About Printing Downloaded Models
If you have downloaded model blueprints from websites like Thingiverse, chances are that they will already be in STL format. This format is halfway to becoming a printable file so stay tuned for how to turn that STL file into something seriously awesome.
For the printer to be able to manage the design files, they have to be sliced which means that it has to be transformed into the exact layer-by-layer description of the object, including the temperature, the speed and wall thickness controls. The resulting file is called a G-Code file that can be interpreted by the printer.
You can choose from a number of slicing applications in the market, including free ones such as ReplicatorG, Cura and KISSlicer. We will talk more about slicing software shortly.
How To Print Maps Terrains And Landscapes On A 3d Printer

From time to time, every 3D printer owner is asked the same question: Why is the printer really good and useful? I cannot imagine what would I use it for. I did not find a satisfactory answer to this simple question at first, because I dont consider printing figures and statues as the right example. Thats why every time the 3D printing technology is applied in practical use, Im excited! Today, Ill show you how to print a 3D map, that can serve in a number of situations not only using our Original Prusa i3 MK3 printer. How about a plastic model of terrain for school education, a small-scale version of a national park, a model that shows the overview of a real-world race track, or perhaps a tiny version of a mountain you climbed in the past. Thanks to these models, we can see the landscape from a birds eye view. Input data will be topographic maps that are most interesting for 3D printing purposes.
Models based on maps can be divided into two groups:

Introduction To 3d Printing Software
Unless youre planning to download ready-made blueprints of models from the Internet and use them to print objects, you will need to understand what kind of 3D printing software you need. We had discussed this topic briefly in the previous chapter we will now discuss 3D printing software in more detail.
File Type Of 3d Print
At the bottom of the settings window, you can decide upon the output of your 3D print.
You can either export it as an STL file or continue with Autodesks print studio to prepare this model for the 3D printer. If you go for the latter option, the selected body will be exported from Fusion 360 and imported to a newly opened Autodesk print studio window.
For some more info about importing and exporting STL files in Fusion 360, read the next chapter. To learn more about preparing your 3D print with Autodesk Print Studio, read on from chapter 6.

How Can You Make Your Own Models
There was a time when Computer Aided Design software was designed by engineers, for engineers. This software used to be extremely complex and no one except those with the proper training could use CAD software effectively.
CAD software has a steep learning curveTimes have changed, and the latest in CAD software is aimed at general users. The best thing about modern CAD software is that it is not as difficult to learn and use as it was previously however, the learning curve is still pretty steep, and you would need to dedicate quite a bit of your time and effort to fully grasp all the concepts of 3D printer-ready design using CAD.
In order to learn the basics of CAD designing software, check out Autodesks 123D Design and Inventor Fusion. Both of these programs are free for limited licences. You can use the free versions of these software tools to design models for printing.
One thing to bear in mind, however, is that the free/limited/student versions of CAD software do not generally allow you to sell your printed objects, or to sell the files you create. As always, you need to do your own due diligence and investigate the licensing for any software you download.
If you plan on 3d printing as a business, then you really do need to invest in a commercial software licence.
We will talk more about software later in the guide.
Tip #: Importing And Exporting
At the start of a project, choose a file format that can comprehensively describe the design while suiting the intended applications and minimizing the need for file conversions. Meshmixer will read numerous 3D file types, such as STL, OBJ, PLY, and some lesser known formats AMF, 3MF, OFF, and the native MIX format. For exporting designs to a different format, Meshmixer also supports Collada, VRML, and Smesh.

How Do I Convert An Image Into An Stl
Converting an image into an STL file requires you first to convert the image into grayscale. Tools like IMAGEtoSTL examine the small details of your print or JPG file based on the luminosity of every pixel. Then it creates the corresponding 3D pixel.
Its luminosity determines the pixels height black pixels have a resistant size which does not get included in the final 3D model.
On the other hand, white pixels generate adequate height, which you can specify once you upload your image.
The STL form may be printed or get further processing by loading it into new models of 3D mesh editing like Blender.
The Blender comes in handy for video game developers to create 3D models from images for games or other apps.
Preparing The 3d Print With Autodesk Print Studio
Autodesk Print Studio takes you through the 3D printing process step by step. The first thing you might want to try is the repair tool, which will automatically detect problems and fix them for you. For example, if your model is not watertight and contains holes in its surface, Print Studios repair tool will fix this for you.
The next steps of the process are only important if you use home printers. You can optimize rotation to let the software determine how to best position the body on the print pad. Then you can automatically add supports. Keep in mind that for online services like i.materialise, you do not need to add any supports as we will add those automatically if necessary. Most of our 3D printers do not even require support structure during their printing process.
In the last two steps, you can preview your print and export the file.
