Our offices will be closed from January 18th to January 31st included in observance of Spring Festival Holidays.
We would like to wish you and your family a very happy Spring Festival and all the best for 2020!
3D printing is a process of making three dimensional solid objects from a digital file.
Some in the industry refer to part of the 3D printing process as Additive Manufacturing (AM), but we’ll use its practical name here—3D Printing. This will keep the guide consistent and easy to read.
The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
3D printing enables you to produce complex shapes using less material than traditional manufacturing methods.
Although there are many different printers available, the four most common are: Fused Deposition Modeling (FDM), Stereolithography (SLA), Digital Light Processing (DLP) and Selective Laser Sintering (SLS). These technologies have significantly impacted the way businesses, professionals, consumers and educational institutions function due to their adoption of 3D printing.
FDM technology is currently the most popular 3D printing technology and used in both affordable 3D printers and even 3D pens, which we happen to specialize in.
3D printers which use FDM Technology construct objects layer by layer from the very bottom up by heating and extruding filament.
SLA, the oldest additive printing technology, works by exposing a layer of photosensitive liquid resin to a UV-laser beam. The resin hardens in the desired pattern, and the object is built one layer at a time. DLP printing mimics the functions of an SLA printer with the main difference being it cures resin using a digital projector and light. A downfall of SLA printing is that the object must be rinsed with a solvent after the printing completes, and even at times has to bake in a UV light to finish the curing process.
DLP refers to a method of printing that makes use of light and photosensitive polymers. While it is very similar to stereolithography, the key difference is the light-source. DLP utilizes traditional light-sources like arc lamps.
In most forms of DLP, each layer of the desired structure is projected onto a vat of liquid resin that is then solidified layer by layer as the build plate moves up or down. As the process does each layer successively, it is quicker than most forms of 3D printing.
SLS printing is when a laser is used to solidify and bond grains of plastic, ceramic, glass, metal or other materials into layers to produce a 3D object. It works like other additive manufacturing technologies in that it provides a print by building layers-upon-layers until the object is complete. Once the laser traces the pattern of each layer slice into the bed of powder, the bed lowers and another layer is traced and bonded on top of the previous. A major benefit of SLS printing is that it does not require a support structure to produce intricate designs.
The Spring Festival or Chinese New Year is the biggest occasion in China. This year, the Chinese New Year falls on January 24th and we will be saying goodbye to Year of Pig and welcoming the Year of Mouse. As Chinese people prepare for the new year, there are customs and traditions that are followed by the masses. One such custom is the “annual party” held by companies for their employees.
In appreciation of the hardwork put in by all JGAURORA members, and the continuous support from all business partners throughout the year of 2019, JGAURORA held its 2019 annual party on 10th of Jan 2020.
At the beginning, Ms. Wu Jie, the deputy general manager of JGAURORA, has delivered keynote speech. She summarized last year, thanked everyone for the efforts and explained the direction for this year.

Onshape, a modeling software specially oriented to design technical and spare parts, was the first full-cloud 3D software created.
It’s a good option for beginners because it has a free version for uncommercial and educational use available by registering on their website. Users will be able to sketch basic geometry, extrude objects and combine them very easily. It also has a clean user interface and is compatible with mobile devices like tablets and Android and iOS smartphones, so users can update their designs everywhere they go.
7. Fusion 360
Also developed by Autodesk, Fusion 360 is a powerful and accurate software that allows users to do parametric modeling, extrude shapes or create free forms.
It’s a professional software used in disciplines like industrial design, so it’s a little more complex to use, but we consider it to be a good choice for beginners because, once you have practiced with an easier 3D modeling software like those above and you have understood the basic concepts, it becomes very easy to use.
Fusion 360 also has a pro version and a free one for students and hobbyists.
FreeCAD is an open source parametric 3D software launched in 2002 that has become an alternative to other expensive software like AutoCAD.
As the name implies, it’s completely free. It has a complete set of design tools that allow users to create more detailed and complex models.
It may not be the easiest software for beginners to start with, but the learning curve allows you to learn more and more with every use. The best part of this software is that being open source, it allows the users and the developers to add new modules and tools over the years.
It’s probably the best option for beginners who want to get fully involved in the world of CAD.
Sculptris is a 3D software focused on digital sculpting. It can be considered as an introduction to learn a more professional software like Z-Brush.
Sculptris allows users to edit any mesh with a variety of brush strokes, as well as map or paint textures for 3D models. The software is still available for free in the Pixologic website, but it’s no longer in development, so they warn you that it may not run in newer operating systems. However, if you’re interested in digital sculpture it’s worth giving it a try.
Finally, we know Blender may not be an easy-to-use 3D software for beginners, but it makes this list because it’s completely open source and free.
Even if you’re not familiar with 3D modeling, you can play around with some features like the Modifiers menu to give your models a different appearance. For example, users can use the “Decimate” tool to get a “low poly” effect or the “Remesh” tool to get a voxelized shape, or maybe the “Solidify” tool to give some thickness to the walls of the model for 3D printing. You can also use the Subdivision surface tool to give your model a smoother shape.
It has a lot of features and modeling styles and is a very powerful software, but even for beginners, there are some things they can do to start learning how it works.
As you can see, the range of 3D software available is huge, but when you know exactly for what are you going to use it for, the choice becomes easier.
You have to feel passion for what you’re doing in order to make the learning process more enjoyable and faster. As a beginner, the only way to know if a 3D software is the right one for you or not is by trying it out until you feel comfortable.
When you master one, you’ll be able to use and learn others in less time. So, go ahead, we encourage you to experiment and practice to achieve your goals and make your own projects. With the list of options we have provided here, you have a lot to choose from.
3D modeling takes a lot of practice and skill. Check out 10 free & easy 3D modeling software tools for beginners that will get you 3D modeling in no time.
3D modeling for beginners, or those who are not familiar with the world of CAD, can be confusing and maybe a little frustrating at first, but knowing your options and the basic concepts is the best way to start.
3D modeling is a necessary skill when you want to create or design your own objects. As a beginner in this topic and with the actual offer of 3D modeling software out there, it can be difficult to select one that fits your needs, but don’t worry. Here we present you with a list of 3D software and tools we think anyone without prior knowledge should be able to use with a little practice. Best of all, they’re free to use!
Tinkercad is an online free 3D modeling software created by Autodesk.
It has a friendly interface and that’s because it was designed for educational purposes, specifically for kids and people with no experience in 3D.
Tinkercad is probably is the most accessible 3D modeling software because it teaches all the basic concepts of 3D, allowing you to convert an idea into a CAD model by simply dropping and dragging primitive shapes, such as cubes, cylinders or spheres.
It also has a connection with different 3D printer services and with some practice, you can make your first 3D model very quickly.
Vectary claims to be the easiest 3D design tool and it has very good reasons to think this.
Firstly, it’s an online-based software with the capacity to 3D model and render images in real time. It was created for designers and makers focused in graphic, product and game design, as well as for 3d printing, but it can be used by anyone interested in 3D modeling.
Vectary doesn’t require previous experience, just a basic knowledge of the concepts. It works with a drag and drop interface, making it not just easy, but very fun to use. It’s a great and powerful tool for beginners to learn. It also has a free version, which you can access by registering on their website.
SketchUp, considered by many as the easiest and most flexible 3D app available, has been around since 2000. It has two versions: free and pro.
We’ll focus on the free version since it’s more accessible and everyone can use it by simply registering an account on the website. The free version is now a web-based software and it’s a great choice to start with, due to its easy learning curve, clear and intuitive tools and a very friendly user interface.
But don’t get confused: Sketchup is very powerful and that’s because it was originally created for architects, designers and filmmakers. That means that you should be able to design complex and large objects too. In fact, in the pro version, you can add plugins or tools to enhance the productivity and capabilities of the software.
MatterControl is a free, open-source software you can download from the MatterHackers website.
It’s geared toward the maker community, specifically for 3D printing. It’s very intuitive and it has a design toolset that allows you to create something from scratch or customize existing models.
MatterControl also has a slicer function for your models to get them ready for the 3D printer. It may be suitable for beginners to start manipulating their models and get familiar with some terms.
Meshmixer is a pretty simple software developed by Autodesk and created to manipulate and modify any 3D object. In a few words, it’s like Adobe Photoshop for 3D models.
That makes it a great beginner software, especially for 3D printing hobbyists because Meshmixer has the capacity to edit, repair and optimize any model. It has some sculpting tools for volumes and surfaces which everyone can learn by playing around a bit. And, of course, it’s completely free.
How do I edit STL files? That is something any 3D printer owner sooner or later wonders. After all: Ready-made STL files are fine. But what if an STL file you downloaded lacks some features, is damaged or you need only a part of it? That’s when you need an STL editor.
Editing STL files can be done in two different types of modeling software:
On the one hand, there is CAD software (Computer Aided Design). It’s tailored for construction, provides exact measurements and solid modeling. These tools were not made for 3D printing in the first place. In CAD software, circles, for example, are “real” circles; in 3D printing – and in STL files for 3D printing – circles are represented as polygons. So CAD tools cannot show their full strength when editing STL files. Nevertheless, they can be used for working with STL files. Three of the four tools we present in this article are true CAD tools: FreeCAD, SketchUp, and Blender.
On the other hand, there are mesh editing tools such as MeshMixer and MeshLab. They are designed for modeling, animation, and objects represented by a 2D surface. That means: These objects have just a shell and no filling. This may cause paper-thin walls, which can’t be 3D printed, if the object is not solidified (which, however, can easily be done in tools such as Meshmixer). In fact, mesh editors are excellent tools when it comes to editing STL files.
A partnership struck back in 2018 between Volkswagen and HP’s 3D printing wing has borne fruitful progress, as the German automotive company recently reached a milestone using the HP Metal Jet system, a metal 3D printer touted for its ability to manufacture high volumes of production-grade metal parts.
After announcing a three-phase strategic roadmap leading to the functional production of automotive parts, Volkswagen has reached an important milestone in the first stage of this plan, producing over 10,000 miniature ID.3 models ahead of the electric vehicle’s long-awaited launch event. The Volkswagen ID.3 is the company’s first fully-electric production car offering a CO2-neutral footprint.
“What better way to showcase the innovation of Volkswagen than to use our own technologies in the marketing campaign for the premiere ID.3 launch,” said Dr. Goede. “We are extremely pleased with the technical features and the speed, quality and low cost per part that HP Metal Jet has provided. The surface quality and feature resolution enabled great attention to detail and made it possible to add a special touch to this important company milestone.”
This is just the first accomplishment of the collaboration, which also includes GKN Powder Metallurgy, as Volkswagen eventually plans to use the HP Metal Jet system to 3D print structural parts for the next generation of vehicles. Aiming to increase in-part size and technical requirements, the automotive manufacturer hopes to produce between 50,000 to 100,000 soccer-size parts per year.
The HP Metal Jet could be utilized to produce higher performance functional parts with critical structural requirements, including custom gearshift knobs and mirror mounts. Volkswagen also intends to use the metal 3D printing system for other applications in the near future, including the production of lightweight metal parts that still meet stringent safety requirements.
Siemens and Materials Solutions opened a 17,000-square-foot innovation center — “the only one of its kind in the U.S.” — this week in Orlando, Florida.
Design, manufacturing, robotics, rapid prototyping, digital tools, and metal additive manufacturing come together in the large center to facilitate problem-solving for Siemens’ energy businesses, with additive manufacturing services from Materials Solutions supporting the center as well as outside customers. Particularly in focus are applications in energy and aerospace, with Orlando representing a key strategic location within the US for such activity.
“This center is unique, bringing together a multitude of our innovative processes under one roof,” said Tim Holt, COO of Siemens Gas and Power.
