I was born in Italy, I am 47 years old, I have a university degree in engineering engineering and I started my professional career in this area. Subsequently, I worked in many other industries: aviation, military, automotive and gas. Below you can see pictures of some of my projects.
I left Italy in connection with my work, it was in 2006. Eight years lived in the Middle East, in Qatar, and since 2014 I live in Moscow.
I work as a design engineer, I have extensive experience with 3D CAD (I use SolidWorks) and FEM / CFD (ANSYS). I dealt with CAD 3D for the first time in 1997, when the first economically acceptable software (Solid Edge and SolidWorks) appeared on the market.
Introduction to 3D printing
I first encountered a 3D printer in 1988, as part of a visit to the FIAT research center. Then the 3D printer cost as flat and was the size of a cabinet. I remember how he struck me. The ability to draw an object, and after a few hours to pick it up, seemed like a fantasy. Twenty-five years later, in 2013, I had the opportunity to purchase my first 3D printer, this was Flashforge Creator Dual Extruder.
Now I am working with a Raise3D N1 Dual printer, which has made some changes.
How to choose equipment
I chose this car after a long search on the Internet. My choice is based on the following factors: the possibility of high-temperature polycarbonate printing , the possibility of making further improvements in the firmware and software, and compatibility with Simplify3D - the software that I use in preparing for printing.
I chose Simplify3D software because of its flexibility and ability to vary printing parameters. My parts are often very complex, require accuracy in size and full control over print parameters. Considering all the advantages of this software over free counterparts, I believe that the price of the license justifies itself.
I bought the Raise3D N1 Dual at the Top 3D Shop in February. Then I was struck by another printer -PICASO 3D Designer X Pro , but, unfortunately, its price exceeded my budget, although I am sure that it is worth it. In addition, at that time he had not yet entered the free market.
What benefits did the printer bring?
With this printer, I can print parts from complex materials like polycarbonate and nylon without any problems . Print resolution remains impressive and reaches 0.005 mm (with a nozzle of 0.2 mm). The print area is also impressive. A big plus can also be called a large convenient touchscreen for settings.
What tasks does it apply to
Despite the change of work in 2005, when I retrained from a design engineer to a project manager, I never left engineering.
Now this is one of my hobbies. It allows me to relax and get a charge of vivacity.
In addition, I am engaged in modeling: I am building models of ships, aircraft and tanks from wood and plastic.
3D printers once again aroused in me a passion for designing machines and raised it to a higher level. Some of my projects are available on my page on Thingiverse , while others are stored on my hard drive, pending completion and implementation.
Now I am working on a very ambitious project, a new type of gas turbine for aeromodelling. This is a complex and interesting project that requires knowledge in various fields of physics and applied mechanics, such as structural mechanics, vibration mechanics, disk mechanics, hydrodynamics, aerodynamics, the theory of lubricants, metallurgy, heat transfer, combustion dynamics, etc.
All this is complicated by the miniature dimensions of parts for such an engine.
The basis of this project was the well-known and widely used KJ66. This engine was originally designed taking into account the production of most of its parts on a 3D printer made of aluminum, titanium, hastelloy and inconel. In addition, it uses some common technical solutions from aeronautics that have never been used in aeromodelling before - it was impossible. Now they can be played on a 3D printer.
Printing prototypes of plastic parts, in any case, is the main link in the whole process: from design to the final product. It is necessary to study and fine-tune every detail.
Now some details are already at the final stage of production.
Sometimes I print products for my other hobbies - robotics and automation.
This picture is another one of my current work. This is an autonomous rover, equipped with an independent navigation system, a robotic bracket, a speech recognition system and a voice synthesizer.
How such problems were solved before
My previous printer did not provide accuracy in size, because did not have good articulation and demanded from me a lot of mechanical modifications and alterations. He also had limited print area and I had to print the parts in parts and then glue them together.
Is it even worth mentioning that without a 3D printer, access to such rapid prototyping and using 3D printing as a hobby would be impossible?
What did you like about working with Raise3D N1 Dual
The advantages of this printer are as follows:
- Neat in size
- Print resolution
- Print quality
- The print chamber is fully enclosed and allows printing from materials that require a thermostatic print chamber, such as nylon.
What can be improved
I replaced the print head coupling made of a piece of plastic corrugated tube with a conduit used in CNC machines. It is not expensive, it cost me about one thousand rubles.
I replaced the original nozzle with Olsson Ruby, with which I can print without problems with abrasive materials, such as filaments containing carbon and metal-filled.
I added a thermometer to control the temperature in the print chamber, it helps when printing from ABS, nylon and polycarbonate. Replaced the power supply system kit Bondtech, and also added radiators to avoid overheating.
The printer, which already printed very well, according to my subjective assessment, became even better after these changes. Print quality has reached a score of 10 out of 10, while the original version was 7 out of 10.
I also plan to replace the motherboard cooling fan with a quieter one, and stepper motors drivers with TMC2208.
If we talk about the future, then I am sure that printing of metal parts on a 3D printer may become available at the level of a simple consumer.
New plastics will also expand the functionality of printers, materials such as PEEK, polycarbonates or carbon fiber-reinforced nylon, which did not exist 5 years ago.
Five-axis printers will allow to overcome the low structural resistance on the Z axis, that is, to increase the vertical strength.
You can see my work on my page on Thingiverse .
For several years in a row, due to the main work, I did not have enough time for new projects, but now the situation has improved. I hope I’ll finish my new engine and rover soon, so stay tuned.
