The Portuguese center creates a 300-kilogram piece on a 3D printer.  Do you want to make a house of 144 m2 [vídeo]

The Polytechnic Institute of the Center for Rapid and Sustainable Product Development (CDRSP) of Leiria has created a 300 kg plastic object, Artur Matheus, deputy director of the research institution, said.

“This is possibly the largest 3D printed product in Portugal using the Portuguese extrusion system. There are companies in the United States that make parts by the ton,” and “some in Europe,” he said.

In Portugal, he said he did not know an item of this size had ever been made and it was “the first 300 kg plastic item made at CDRSP”.

“We have already made a two-ton cement stone and are developing a machine to make – this will be a case study – a 12 x 12 square meter family home. [144 m2] on a 3D printer,” he added.

This is a “small bus stop module”, which took about 20 hours to build, was conceived and designed by Weadd and produced using the technology of Periplast, a Leiria-based plastics extrusion company. industry market.

“Many Portuguese companies are already looking into this because it allows us to produce molds from recyclable thermoplastic materials for large composite material components,” the researcher said.

Arthur Matheus gave the example of a boat mould, which typically uses thermosetting resins or Styrofoam.

“Eventually Styrofoam goes into civil engineering to try and use it to mix cement, and the resins end up in landfill. Being made of thermoplastic, it allows it to be manufactured in what is known as a monocoque, which is a single piece that can be hollow, thermoplastic ribbed, and at the end of its life it will be crushed and made again in a different shape.” , – said the deputy director of CDRSP, emphasizing the environmental friendliness of the product.

The stop module, created last week, was created to showcase the Add.Additive mobilizing project, led by ADIRA, a company of the Sonae Capital group, which involves several Portuguese universities and companies.

“It was created to showcase the technology. We made two parts, one of which was 75% recycled, but it turned out to be less successful. We have to set things up. It’s done, with little problems that we understand how we can solve,” he said.

The next step could be to present the project to the mayor of Marinha Grande “so that a bus stop can be installed in the industrial area” where the CDRSP operates, based on this formless process.

“Perhaps we could make a composition that suggests a place where a person can sit, a place where he can stand and write something. It could be a recycled and translucent material to create a smaller visual effect,” he acknowledged.

Arthur Matheus also said that CDRSP will be involved in creating the mold for the small float of the catamaran.

“It will be made from plastic collected (one ton) from the sea off Tavira. We’re going to use calcium carbonate from oysters and other shells that come from the food industry to make the compost more stable and with less compression.”

“We do things every day that don’t impress. They serve to communicate with society and create expectations. Expectations feed us and give us more opportunities to nourish the motives that make us move forward,” he stressed.

Thiago Monteiro in 14th and 15th before the arrival of the WTCR in Portugal – Observer



Thiago Monteiro in 14th and 15th before the arrival of the WTCR in Portugal - Observer

Portuguese driver Thiago Monteiro (Honda) finished 14th and 15th this Sunday in the two World Touring Car Cup (WTCR) races held in Aragon, Spain, which precede the Vila Real race.

The Portuguese rider always rode in the tail, he was hindered by the fact that Honda had more excess weight than his rivals.

“If they told me that I would be in this position, I would not believe it. But the reality is that we have not been able to withstand a number of adversities. From the moment when the pace is much lower than other rivals, we are prepared in advance. It’s heartbreaking,” the Portuguese rider began his explanation after the fourth round of the championship.

The Portuguese rider struggled to find the best balance in his Civic, as did his teammate, Hungarian Attila Tassi.


“We still had problems, and we could not reach the full potential of the car. It was very difficult, unpleasant and discouraging, especially since we are going to Vila Real and this scenario does not suit me. But we will have to continue to look for our own path and believe that everything will work out, ”Thiago Monteiro concluded.

Belgian Giles Magnus (Audi) and Spaniard Mikel Ascona (Hyundai) won both races on Sunday.

Ascona leads the league with 129 points, while Thiago Monteiro is 16th with 12 points.

The WTCR competition in Portugal will take place next weekend in Vila Real.

Portuguese military admits ‘it will take time’ until territory is taken under control



Portuguese military admits 'it will take time' until territory is taken under control

The “path” chosen for about a year in the fight against rebel groups in the province of Cabo Delgado in northern Mozambique is “the right one,” Brigadier General Nuno Lemos Pires said in an interview with Lusa.

“Now, while the situation is not fully under control, we all understand that, as in any other counter-terrorism situation in the world, it will take a lot of time,” added the head of the European military training mission, although he acknowledged that this “ does not mean that sometimes there are no fears and failures.

However, “this is part of what constitutes an action taken against terrorists who operate in a very wide area, who in themselves have the initiative and the ability to hide in a very wide area,” he said.

In fact, he stressed, many of the recent attacks that have taken place in the south of Cabo Delgado in recent weeks are due to the fact that Islamist extremist rebels had to “flight from the north” of the province.

“Because this was a consolidated military operation carried out in close cooperation between the Mozambique Defense and Security Forces (FSS), [e com as forças d]Rwanda and SAMIM (Southern African Development Community Mission (SADC) in Mozambique), who were clearing out the intervention areas that existed in the area, the reaction of many terrorists was to flee the area, go further south, where they were not pursued. , and make new attacks,” he explained.

“In such cases, the initiative almost always belongs to the terrorists. There are few of them, they hide among the population, they move over very large territories, with a lot of dense vegetation, it becomes very difficult to find them, but you can easily move,” he continued.

On the other hand, the Portuguese general emphasized, “it is now difficult for these groups” “to concentrate power and forces for large-scale operations, as was the case three years ago during the conquests, such as Mocimboa da Praia or Palma.” ,” he said.

“They don’t have that ability. Many of these attacks even demonstrate [estratégias] survival [clássicas das guerrilhas]. They’re looking for food, they’re looking for supplies, they’re searching deep down for a place where they can survive, because the area is already under quite a lot of control. [por parte] Mozambique FSS, Rwandan forces and SAMIM,” he explained.

In this context, Nuno Lemos Pires highlighted the “quick response” of the Mozambican authorities to each of these developments, starting with head of state Filipe Nyusi.

“I think it is exemplary that the moment there is a movement or a series of significant attacks in other areas, we immediately see the President of Mozambique heading north, linking up with his Chief of the General Staff of the Armed Forces (CEMGFA). , with the Minister of Defense, with the Minister of the Interior, and outline plans on the ground for a quick change of equipment and the ability to respond to such movements,” he said.

During one such trip to northern Mozambique in mid-June, Mozambican Interior Minister Arsenia Massingue said that Mozambican police were informing the “enemy” – the rebel forces in Cabo Delgado – about the positions of the FDS and allied forces on the ground.

However, Lemos Pires downplayed the situation. “We must be aware that there are infiltrations in any political system. It’s happening everywhere. Ignoring this dimension is tantamount to ignoring what is happening everywhere,” he said.

“I don’t know of a single case of insurgency, counterinsurgency, terrorist or counter-terrorist combat where these leaks didn’t happen frequently. You need to be careful. .

In addition to the vastness of the territory that has been the scene of conflict and the topography favorable to insurgent guerrilla strategies, the porous borders with Tanzania to the north of Cabo Delgado and Malawi to the northwest also pose a danger. challenges the SDF and allied forces of SAMIM and Rwanda.

Lemos Pires also relativized this question. “We are talking about transnational terrorism, and it is good to understand that the situation in the north of Mozambique, in Cabo Delgado, is not limited and is not limited – and has never been limited – exclusively and exclusively to this region. A phenomenon that exists throughout Africa. , namely in Central Africa,” he said.

The UETM commander even took advantage of this circumstance to formulate an “extended response” to “a broad problem, a regional one, and the solution must also be a broad regional one.”

Therefore, “it’s very good what we see here on the ground, in fact, this is the unification of the efforts of regional African forces to try to deal with a problem that really worries everyone,” he concluded.

“What happens in one region can affect another. That is why it is in everyone’s interest that these groups be fought, detained and that the narrative that they are currently spreading can be counteracted – we hope that there are fewer and fewer successes,” the Portuguese general stressed.
