Makerfaire Rome summary

, ,

The weekend of October 14-16th Natural Robotics participated at Makerfaire Rome. This is a short summary of our experience as exhibitors.

Makerfaire Rome is the biggest maker fair in Europe, and this is confirmed by the 110,000 visitors that attended in three days.

We were quite busy, so we could not see much from the other pavilions, six in total.

Friday morning was dedicated to schools. 25,000 kids from six to eighteen years old going around the stands and asking a lot of questions about everything. In those cases, the models always are more attractive than the machines to them. In the afternoon it opened to general public.

In our booth you could see a Delta Black that we had printing all day at different speeds, since printing speed id its major advantage. We also showed the version 3 prototype of our low cost laser sintering 3D printer: the VIT.

The Makerfaire has low professional focus, more focused on makers and families. Even that, we saw a lot of interest in the laser sintering machine either from distributors as well as 3D printing services businesses, that want to widen their technologies offer. There were also people interested for other specific topics like jewelry design, electronic cigarettes, etc.

Our pavilion was fully dedicated to digital fabrication. And we could see and meet other laser sintering projects that are also targeting the low cost range. For example with the nice and friendly Sintratec team we made a good exchange of knowledge, mainly about the common challenges of this technology that we had to face during the prototypes development and how each project took different approaches to sort them out.

IoT: Using 3D printing to prototype electronics cases


Last week we joined an event from the Barcelona Internet of Things group (IoT).

We thought that the best use case for 3D printing applied to IoT is to prototype cases for the electronics usually used, since IoT definitely implies hardware.

The presentation had a 10 minutes limit, so we showed a simple case: how to modify an Arduino Uno case.

It is not about reinventing the wheel each time, but to benefit from shared models that already exist and modify them to our needs.

The Thingiverse repository

We showed how Thingiverse can be a good starting point:  searching for “arduino case” we got 1000 results! Sure there is something you can reuse….

Note that there are other repositories also very valid, like Youmagine.

In this example we take an Arduino Uno case designed by ZygmuntW.

And we download the STL file belonging to the base. We already have a base with the proper size and measures and the correct supports.

Modifying with TinkerCAD

Now we upload into TinkerCAD, one of the most simple modeling apps that we recommend as a first choice to get in touch with 3D modeling. What’s best is that it is a web app and it allows to import STL files and modify them, exactly what we need.

STL simple treatment is one of the advantages of TinkerCAD. There are many CAD apps that do not allow working with STLs directly, or need to go through a process to convert the mesh into a model that the app can understand. And they oblige you to work in their original format, or best case to import the STEP format. If you plan to modify STL files, take this into account when you select your modeling tool.

Using the app we substract “IoT” from the case base. Simply it’s adding the three letters and convert them to holes. TinkerCAD manages the rest and process them as a subtraction of objects.

3D Printing

Then we just have to print it with a Delta Black. The Delta 3D printers are robust, we carried it with our motorbike inside the city and we just did not have to do anything about it, start and print. With the fix base there is no need for calibration.

We launched the printing during the event. The first part of the object was printed at 100 mm/s, and after responding to a question from one of the participants we increased speed to 350 mm/s.

Passion for 3D printing among our clients

Jorge, best known as @akirasan, is one of our clients who recently bought a Delta black 3D printer in KIT format and discovered his passion for 3D printing.

As he is a very active user in Twitter, we have followed his progress during the assembly and the first print tests. Pure passion!

It reminds us how we lived the first time we were in contact with 3D printing. This feeling that anything is possible.

Note: tweets are translated into English below the tweet.

The decision

First thing was to decide for our product. Quite often we tend to put attention in the price as the main purchase argument, and Jorge was asking for opinion on Chinese 3D printers.. Some contacts in Twitter suggested that if he was going to assemble a kit, it was better to go for a company in proximity in case there is any problem or error during the assembly. To ensure it is easy to get support in case it’s needed.

He took the right decision, because we had to some fixes due to an assembly issue.

It’s clear that I am a completely newbie in 3D printing ???? I broke the hot end and I do not know what else

In fact it was simply the fan to cool the hot end wasn’t connected properly, and since it was not working the hot end got too hot. We were able to provide a replacement quickly so that Jorge could continue making progress.

The assembly

For a kit assembly it is crucial to have an adequate documentation, and specially a step by step manual like our assembly manual.

In these cases it is also good for us to get feedback from our clients in order to improve it. It may happen that things that are obvious to us in fact they are not clear enough in the manual.

This is getting the right shape ????????????

And as you make progress you get the satisfaction of seeing how the machine is getting the right shape.

Before and After: Electronics mounted, although it may not seem so ???????????? because everything needs to be tidied up


Starts to look like the original picture ???????????? now calibration and the first test ????

First prints

The most satisfying is to see how 3D printing raises passion among those who initiate in it. With the pride of having assembled it with their own hands.

Probably not the best “hello world cube” 3D printed…but this one is mine and I am more than proud ????????????

Everything can be modeled and 3D printed! from a pokeball to a card holder…

Still quite some work to learn and adjust. But the monocolour @Movilujo pokeball doesn’t look too bad ????

And the most important thing is this feeling of power, not to change the World, but to improve many things around starting by small repairs and mods. This is what really creates the passion for 3D printing. Norbert Rovira, one of our founders, loves to do small repairs or small improvements either at home or with mountain equipment. And he also publishes about it in his blog.

When I am asked why I want a 3D printer, I tell them: it is not “the why” but how it changes my way of thinking and opens my mind ????



I am so caught up that I have already added a provisional webcam to my 3D printer, and I just stay watching how it prints ????????????


Things printed yesterday with direct use in the office. Well, the Pikachu is just for a bit of decoration, but I use the card holder ????

¡¡Congratulations @akirasan!!!

Natural Robotics at ln3Dustry fair – a view from an exhibitor

, ,

Natural Robotics participated as exhibitor in the first ln3Dustry fair that happened in Barcelona from June 21st to 23rd.

This is our view from a small company perspective that exhibited during the three days.

Entrada In3Dustry

We are grateful with the Generalitat de Catalunya for promoting Catalan companies and letting us have some space in their stand (disclaimer: it was not for free and we followed an application and selection process).

One of the drawbacks for us was the layout of the exhibitors’ stands, different from the usual and it impacted us in particular. We were told in advance by the organizers and then found the evening before that the stand of the exhibitor next to us had a big wall mounted, within fair requirements. But we were out of direct sight from visitors.

Fortunately, the fair had a continuous flow of visitors, except at lunch time, and they were also finding our booth.

We were so busy we could not attend any of the presentations and panels that were happening in the Arena. It looked like a pretty busy agenda and in addition you could join the Maker area where other presentations were also held. That’s the only reason to have a three days event, because the exhibition could be walked through in one single day.

In3Dustry arena

We think the event could fit in two days for the current size of the exhibition, to have it more balanced. In fact we don’t know if many visitors repeated several days. Hopefully next year it gets better and bigger and three days are needed to see everything!

One thing that is amazing is that the majority of stands were showing hardware, but it was very difficult to find machines actually working, not even the big Jet Fusion from HP. We had the Delta Black 3D printer printing during the three days. In fact it was raising attention because the movements of a delta printer are quite different from others, and we showed it working at max speed also (500mm/s).

Natural Robotics stand

We didn’t take any risk with the VIT prototype, a low cost SLS 3D printer, due to the use of a powerful 40W laser and its lack of safety measures by now. It’s a prototype! In this case we were only showing the hardware.

The SLS prototype was presented to the public for the first time in the fair. We held its development quite in stealth mode up to that moment. And it had a very good welcome, both from companies that would be interested to distribute or resell it, and from people that already asked to make a pre-order.

The price point is still under decision due to the significant input received, the initial intention was around 10,000€. With a 250x250x250mm build volume and a 40W CO2 laser, these are quite good specs for the price.

The fair organizers Fira de Barcelona did a good job on segmentation of visitors. They were a majority of professionals, just the target of our company. We also appreciated the time spent with us at the end of the event to collect feedback and exchange our views.
To conclude, we have a very positive impression of the fair and the potential benefits it implies for our company in terms of contacts made, feedback obtained and sales leads initiated there.

The event is already scheduled for next year and we will participate for sure, hopefully with a bigger presence.

Event Introduction to Delta/Kossel 3D printers

This last Wednesday the 3D Print Barcelona group organized an event of Introduction to Delta/Kossel 3D printers. The two partners of Natural Robotics are very active members of this group.

In fact this event was a repetition of an event that took place a year ago. In Spain the Prusa i3 had a lot of success as an affordable option for makers and hobbyists and we are used to see Cartesian 3D printers. And the Delta are the big unknown despite their advantages.

Hector made a presentation, using for the demo one of our Delta Black 3D printers.


Evento introducción impresora Delta

The speech first focused in the origin of the Delta 3D printers and how Hector got involved with 3D printing back in 2011, and quickly drawn into the Delta world. His first was a big monster with double extrusion and 1m high aluminum profiles, which gave him many problems and satisfactions.

After this he went through the advantages and disadvantages of the Delta, and more generally of the Bowden system used for extrusion.

To finish, demo time. He put the 3D printer at 500 mm/s speed, managing to overwhelm several people from the twenty total attendees.

Imprimiendo de costado

The Delta Black printing on her side

The head part of the printer is very allows very high speeds that the Cartesian 3D printers cannot even dream. A usual very respectable speed for a Cartesian 3D printer is around 100 mm/s. This is a key specification because it directly determines the total printing time needed. As everything in life, there is a drawback with speed: the faster it goes the higher the risk of an error (think that it pours melted plastic). To print something where quality and detail are important, for all 3D printers you have to decrease speed. But speed for Delta printers will always be significantly higher than for Cartesian ones.
