Interview with Junior Veloso, co-founder of Kevvox

Hello! Today Fabbersinvites you to participate in an interesting conversation with the CEO of Kevvox - Mr. Junior Veloso. At one time, Mr. Veloso during the time was able to consider such a direction in business, research and development, as the production of a 3D printer with jewelry accuracy. Junior Veloso is one of the co-founders of Kevvox, one of the new and innovative manufacturers of professional 3D printers. Recently, the company launched two SP4200 and SP6300 models in the Russian market and established strong partnerships with its Russian distributor. Kevvox printers will be exhibited at the annual exhibition of jewelry and equipment manufacturers in Moscow - Junwex. From October 1 to 5, on the territory of VDNH, in pavilions 75 and 69, a novelty for the jewelry market will be presented.

Since the launch of the Kevvox product line in 2012, Mr. Veloso has been actively promoting the Kevvox brand in Asia, the EU and the CIS. Among other things, Mr. Veloso is engaged in research, inventions and mechanical engineering within his company. In his free time, Mr. Veloso loves traveling. Mr. Veloso has the title of V.A. in Computer Science at PUC University in Brazil.

For greater convenience, we left both a video conversation and
text of the interview under the spoiler.
Mr. Veloso: First of all, thank you very much for inviting me, I will be happy to talk with you.

Fabbers: How did you get interested in 3d printing?
Mr. Veloso: My interest in 3D printing came about 6 years ago when I was looking at some new technologies. I saw some videos about the first FDM machines and I actually bought one of these DIY kits for myself and I was not happy with the result that I got at home. And because the results were not so good, I started to do some research from a technology point of view to get a good print result, and so the interest came and I think that it’s amazing how the industry will be and how it will change the entire production and rapid prototyping business. So it is very exciting to be

Fabbers: Most of your work is done using SLA printing technology. Could you tell me how it works? And can you be called the father of SLA printing?
Mr. Veloso: Good. No, I am not a DLP printing developer, as there are actually other inventors and some other companies using similar technology. So, why did I pay attention to DLP printing, since DLP printing is a high-tech micromirror device that was created and manufactured by Texas Instruments and for this reason I chose this path, mainly because it is a very accurate
and very reliable technology, and as you know, 3D printing can take several hours
and sometimes, depending on the item you want to print, it may take several days. So you need very reliable equipment with high accuracy and repeatability, and this is what enables DLP printing. So, how it works: DLP is a microchip with millions of micromirrors that reflect light, and the way we use it is to use a light-sensitive photopolymer.
This means that these liquids become solid under the influence of light, they have many different types of photosensitivity, from ultraviolet to visible light, depending on the technology and so what we do: we were able to use these very small mirrors
in the microchip to precisely focus the light in the right place in the liquid
and make part of the liquid solidify on a microscopic scale.
This means that we are building the object at the microscopic level and this means that we are building the object by simply letting the light in very small places with high accuracy. This is how it works. This is a very interesting new technology, especially because the main advantage of this technology is that if you have polymers, you can mix them with different materials and as a result you can have different material properties, which is a big advantage compared to other existing technologies because usually with other printing technologies you are attached to only one type of material or to one type of chemical properties.
And this is the main advantage.

Fabbers: How was your company created?
Mr. Veloso: Well, we mostly started in the garage. Well, in fact, not a garage, but a small office at home, we started working on weekends, and we started to have some ideas on how to really create a printer, this involved only two people working part-time on weekends, as a hobby and then we got some investment in order to create our own business and really reach a professional level of development and really, have a company and introduce very professional products to the market.

Fabbers: How do you see the development of 3d printing in the world?
Mr. Veloso: It is developing quite rapidly, because now we see that 3D printing is entering various markets where this was not several years ago. So it was a few years ago in rapid prototyping in industry, which was used mainly to see the design, to check the future product. Now 3D printing is moving into production, for which the use of a 3D printer is relevant, for the production of final products that will be sold or delivered to the client, we we see that this direction is growing very fast, especially in the dental industry and in the medical industry so if you see an industrial hearing aid is already fully in digitalized form Me, then most manufacturers digitize.
You are printing a hearing aid that you really need to personalize in order to match the structure of the human ear. We see many uses of personalized headphones. So if you want to have very specific headphones for your smartphone or iPad, listen to good music, you can pay to have such Headphones designed specifically for your ears and growing in the dental industry, this business is growing in many aspects of various industries.

Fabber: As a manufacturer of 3D printers, what is the most incredible thing that you printed or you saw how it was printed on your printers?
Mr. Veloso: Every day, we are surprised that people print - various things
and in completely different industries that range from toys of famous brands to jewelry of expensive European brands. And it’s hard to say what is the most incredible, but there is one specific dragon that the artist made here in Singapore.
So he printed an amazing dragon, I have one in the office and it’s so beautiful and looks so realistic, because he also painted it. I think this is one of the most amazing things that I saw that could not have been obtained in any other way, besides this, spending a huge amount of time and making sculptures by hand. It is simply amazing how quickly you can get this amazing object out of the printer.

Fabbers: Do you have plans to produce consumer printers or printers for other industries?
Mr. Veloso: So, we have some plans for the release of new printers. Thus, we are developing new printers with even higher accuracy with a large print volume and we are really looking at various markets, including consumers. I think we are ready to launch several new products by the end of this year. We believe that next year we are going to take a serious look at consumer goods. This is not a well-studied market, but we believe that it has enormous potential and we see many opportunities for introducing new technologies,
identifying higher quality high-tech products for consumers.

Fabbers: You only recently appeared on the Russian market and the SP 4300 and SP6200 will be presented at the Junwex exhibition in Moscow. What are your advantages over other manufacturers of 3d printers?
Mr. Veloso: Well, I think that the most important aspect, especially when you talk about professional printers, is reliability. Therefore, if you want your professional printer to work in 24 by 7 format and you do not want to spend time on maintenance, spend time on printer repair, you do not want to spend time setting up and calibrating, but just want your printer to be ready to print. Yes, this is slightly different from public DIY, because they enjoy assembling the printer.
they even enjoy calibration and other things, while professionals do not care about it, they are happy when they get the results that they want to print, and I think that the main advantage in our product is really reliability, because We used the best products and the best components that exist on the market for our products, so if you are talking about mechanical parts, we have high-precision mechanical parts, if we talk about the optical side, we have the best optical solutions. And, it matters a lot.
In addition, there is one thing that matters more that most people don’t understand is that the software makes a difference in the printing process.
so, as a rule, when you model a 3D part, it can be with some small holes, small defects that you need to fix before printing, it looks beautiful only if you visualize it on a computer screen using CAD programs to print real things - this should be perfect
So most of our competitors provide software that will only cut and print your part. But we provide a very powerful solution that comes with all our printers, which allows the user to fix an object or use a number of tools. For example, to build supporting structures, to make part of the object hollow, to make a note to the project, the required size, allow the user to do many things on parts of the object before printing, which ensures a successful result, which means that you will have a higher success rate compared to with other machines where you type, and then find out what was wrong with your facility. And then I have to use various software, fix and print again. So it matters a lot, that we are very strong in hardware and we are very strong in software. So we provide a complete solution, and in addition to this, we offer the best foundry material for jewelry on the market, which of course makes us stand out in the market. So, not all manufacturers today have good casting solutions; they have materials that can be used for casting, but they leave ashes and do not give good results for the jewelry manufacturer

Fabbers: Tell me, is it a joke or is it true that you created all your photopolymers in your garage?
Mr. Veloso: Well, not so much. So, well, when I started, it was a little funny, I had no idea about photopolymers and I just bought some kind of glue in the store, UV glue
on a photopolymer basis and I spent a lot of time trying to improve it and mixing with other substances, trying to get some results when I did it in the garage, DIY, I did a lot of mixing and trying when I had no idea what I was doing, I conducted a lot of research on the Internet. So finally, when we started the company, we hired one very prestigious laboratory, in Singapore, to develop our materials and now, we have engineers and chemists who work for us full time, so actually the person who developed these good the materials are not me. So I know a little, and I'm not really an expert in chemistry. Therefore, we have a person who works with this.

Fabbers: You can talk about the polymers you created, their differences and applications.
Mr. Veloso: So, as I said, the main advantage of this technology is that we can use different materials with different properties. Therefore, we have photopolymers that have various mechanical properties, such as ABS plastic, as polypropylene plastic. These materials are used as a substitute for engineering plastics for prototyping, for small-scale production.
or used as a basis for making a mold, but we have some very good materials, especially injection molding for making jewelry and it is also used in some very expensive toys, but in fact, when you print, it is very similar to the properties of wax, and in fact, after printing, you can melt the models, and use the resulting models to turn them into any material, which can be gold, titanium, silver, so this is a very good material. The
other material that we launch is There is dental material that replaces dental materials in the dental industry. This is a very interesting material, I think that these are the main key materials that we sell today.
And we are very pleased with the results.

Fabbers: And the last question, Junior. I would like to ask ... Your company is located in Singapore, but you do not look Chinese? :)
Mr. Veloso: Yes, that's right, I do not look like the Chinese. I live in Singapore, but I spend most of my time traveling, I myself come from Brazil, but I live in Singapore for about 6 years.
I lived in Asia for about 10 years, and lived in many parts of Asia, including China, Hong Kong, Australia, yes, I have been there for a long time, but yes, I come from Brazil.
