Si l’impression 3D permet d’économiser de la matière en ne déposant le matériau que là où il est nécessaire, il n’empêche qu’elle génère des déchets. Que faites-vous des impressions ratées, des chutes de filament ou tout simplement des pièces que vous souhaitez jeter ? La jeune structure Creative3DP, menée par Priyank Pal, a imaginé ExtrudeX, une machine accessible et facile à utiliser afin de pallier ce problème. L’idée est de pouvoir transformer tous ces déchets plastiques en filaments réutilisables, directement depuis votre atelier ou votre maison. Lancé et financé sur Kickstarter, ce projet, à imprimer en 3D chez soi, a rencontré un franc succès, montrant qu’il est possible de boucler la boucle !

L’idée d’une telle machine n’est pas nouvelle et quelques noms nous viennent en tête comme l’entreprise néerlandaise 3devo. Il faut dire que de telles solutions sont très intéressantes car elles favorisent le recyclage, l’économie circulaire et des circuits locaux courts qui permettent de travailler en toute autonomie. Mais alors, en quoi ExtrudeX est-elle différente ?

La machine ExtrudeX se veut facile à utiliser et accessible


Caractéristiques clés de l’ExtrudeX

À en croire son créateur, il s’agit avant tout de proposer une machine plus compacte, légère, et qui puisse convenir aux makers et aux environnements domestiques. ExtrudeX mesure 65 cm de long et peut donc être facilement placée sur une table à côté de votre imprimante FDM par exemple. Dotée d’une poignée latérale, elle est aussi facilement transportable.

Mais ce qui est particulièrement intéressant, c’est qu’elle se construit directement à la maison. Elle est composée de plusieurs pièces imprimées en 3D comme le châssis et le système d’extraction. Elle se veut moins chère à fabriquer et peut être facilement réparable si un composant se casse ou est usé. Quant aux autres pièces comme le moteur et composants électroniques, on peut facilement les acheter localement. L’avantage d’une machine DIY est qu’on comprend bien mieux comment elle fonctionne, facilitant ainsi son utilisation quotidienne.

Côté matériaux, l’ExtrudeX peut traiter des matériaux de support, des impressions ratées, des granulés propres : tout peut se mélanger afin de créer un filament d’impression. On précise que seuls le PLAl’ABS et le PETG sont pour l’instant compatibles.

Réglez facilement la machine en fonction du plastique à transformer


Comment ça marche ?

Concrètement, comment fonctionne l’Extruder ? Six étapes sont nécessaires :

  • Coupez vos déchets plastiques – vous pouvez utiliser un broyeur ou des ciseaux ;
  • Chauffez votre ExtrudeX en fonction du plastique utilisé ;
  • Placez votre plastique découpé dans la trémie ;
  • Démarrez le moteur ;
  • Insérez le brin extrudé dans le mécanisme d’extraction ;
  • Attendre le refroidissement et récupérer le filament.

Creative3DP recommande de mélanger 40 % de déchets broyés avec 60 % de granulés plastiques vierges et toujours avec la même matière – vous utiliserez donc vos chutes de PLA avec des granulés PLA.


La campagne Kickstarter est déjà terminée et la machine peut être achetée sur le site de Creative3DP pour un peu plus de 200 euros. On vous invite à consulter la page ICI pour en savoir plus – pour l’instant, elle est en rupture de stock.

 La bio-impression de tissu hépatique pourrait devenir une alternative aux greffes

projet live

Une équipe de recherche de l’université Carnegie Mellon, à Pittsburgh, a reçu un financement de 28,5 millions de dollars de la part de l’agence ARPA-H pour mener à bien le projet LIVE (Liver Immunocompetent Volumetric Engineering). L’objectif ? Fabriquer du tissu hépatique fonctionnel pour les patients souffrant d’insuffisance hépatique aiguë grâce à la bio-impression.

Le foie est l’un des organes les plus résistants du corps humain. Vous ne le savez peut-être pas, mais il est capable de remplacer ses cellules en réponse à des lésions aiguës et chroniques, un processus appelé « régénération hépatique ». La littérature actuelle sur le sujet nous apprend que la régénération du foie s’effectue par différentes voies, telles que l’activation des cellules hépatiques ou la reprogrammation métabolique. Cependant, ces solutions ne fonctionnent pas toujours pour tout le monde. Le projet LIVE a été créé pour relever ce grand défi de santé publique.

La première chose à comprendre à propos de ce projet est qu’il ne vise pas à créer un organe permanent dès le premier jour, mais plutôt un tissu hépatique temporaire qui donnera à l’organe le temps de se régénérer. L’équipe, dirigée par le Dr Adam Feinberg, utilisera deux technologies de pointe développées au sein même de l’université. D’une part, la technologie FRESH (Freeform Reversible Embedding of Suspended Hydrogels) qui est une technique de bio-impression qui permet d’extruder des bio-encres souples, telles que le collagène, dans un hydrogel thermoréversible. Cela empêche les structures de s’effondrer sous leur propre poids, créant ainsi des architectures vasculaires complexes et précises à partir de protéines structurales et de cellules humaines.

La deuxième technologie utilisée sera 3D Ice Platforms. Il s’agit d’une technologie complémentaire qui utilise des processus de congélation contrôlée pour créer des échafaudages présentant une porosité interne spécifique, essentielle à la survie cellulaire et au flux de nutriments. Grâce à ces technologies, il sera possible de créer un tissu composé entièrement de cellules humaines et de protéines structurelles, éliminant ainsi les composants synthétiques qui sont souvent rejetés par l’organisme ou provoquent une inflammation.

L’un des principaux obstacles à la transplantation d’organes, qu’ils soient bio-imprimés ou non, est la réponse du système immunitaire. Le projet LIVE s’attaque à ce problème en utilisant des cellules hypoimmunes. Ces cellules ont été génétiquement modifiées pour agir comme un « donneur universel », permettant au tissu imprimé d’être compatible avec n’importe quel patient sans avoir recours à des médicaments immunosuppresseurs, qui sont souvent toxiques pour les fonctions rénales et hépatiques. « L’objectif est de créer un morceau de tissu hépatique qui servirait d’alternative à la transplantation », explique le Dr Feinberg. « Le foie que nous créons aurait une durée de vie de deux à quatre semaines, ce qui laisserait suffisamment de temps à l’organe d’origine pour se régénérer. »

L’ampleur du projet a nécessité la mise en place d’une équipe multidisciplinaire, composée d’experts de l’université de Washington, de la clinique Mayo et de la société FluidForm Bio, Inc. Le calendrier est ambitieux : d’ici cinq ans, l’équipe espère disposer de foies bio-conçus à l’échelle adulte prêts pour les essais précliniques.

Bien que l’accent soit initialement mis sur l’insuffisance hépatique aiguë, les capacités de biofabrication sont évolutives. Dans un communiqué de presse publié par l’université Carnegie Mellon sur le projet LIVE, il a été déclaré que si l’on parvenait à imprimer un foie fonctionnel et correctement vascularisé, la technologie pourrait être adaptée pour construire des cœurs, des pancréas et des reins, une solution qui pourrait réduire les listes d’attente pour les transplantations.

House Launches Investigation Into 'Discriminatory' South Korean Regulators After Trump Hits Seoul With 25% Tariff

The House Judiciary Committee has opened a formal investigation into whether South Korean regulators are unfairly targeting American technology companies, as the two allies with a long history of economic and security cooperation find themselves embroiled in a heated dispute over trade, technology, and regulatory oversight - with government accusing the other of unfair practices.  

Last October we highlighted that South Korea has effectively been extracting money from US tech firms in the form of fines and other punitive measures via the Korea Fair Trade Commission (KFTC). While the commission's stated goal is to enforce antitrust laws, they've essentially morphed into bridge trolls, according to US officials. 

In 2016, Qualcomm was hit with an $854 million penalty for what it called unfair business practices. In 2021, Google was hit with a $177 million fine for dominating the Android OS market. Apple, Meta and others have been similarly hit stemming from issues like in-app payment restrictions, proprietary algorithms, and alleged anti-competitive practices.

While Washington DC has allowed Seoul to pursue enforcement actions under the longstanding US - Korea alliance, the KFTC has morphed into an aggressive, often unpredictable enforcer whose investigations and fines have disproportionately targeted foreign market leaders.

According to one analysis, punitive fines from the KFTC are set to cause a combined $1 trillion in economic losses over the next decade ($525 billion for the U.S. and $469 billion for South Korea), as tighter controls on global tech firms present a "discriminatory" risk that could chill innovation and foreign investment.

Trump Takes a Swing

Following an October trip to Seoul by President Trump, it looked like the KFTC was willing to back off - only for things to go sideways less than two months later, resulting in the Trump administration canceling a key bilateral trade meeting.

Trump publicly accused South Korea last week of "not living up" to the terms of the October agreement, before slapping a new 25% tariff on Korean imports to the United States - blindsiding South Korean officials and sending ripples throughout the business community. South Korea notaly imported around $123 billion of goods to the US last year, making it the second largest export market after China. 

Now, the House Judiciary Committee is on the case - launching an investigation into the KFTC, and have subpoenaed American e-commerce giant Coupang for documents and testimony, after the KFTC threatened massive penalties in the wake of a November 2025 breach, which exposed personal data of over 33 million customers (later expanded to include 165,000 more), attributed to a Chinese hacker but compounded by Coupang's alleged inadequate cybersecurity and delayed detection. Coupang has faced over $100 million in previous fines over alleged search engine manipulation and unfair business practices. According to the lawmakers, obtaining records from Coupang will help Congress assess whether foreign regulatory policies and enforcement practices are affecting Americans’ due-process rights and the ability of U.S. companies to compete in global markets.

Coupang has vowed to fully cooperate, "including submitting the documents requested in the subpoena and having witnesses appear."

In a letter dated Feb. 5, Committee Chairman Jim Jordan (R-OH), and Subcommittee Chairman Scott Fitzgerald (R-WI) said the probe will examine whether foreign laws and enforcement actions are being used to discriminate against U.S. firms and undermine their ability to compete globally. 

Coupang, which is listed on the New York Stock Exchange, has become a focal point for U.S. officials, lawmakers and investors who argue that Seoul’s regulatory approach warrants closer scrutiny. In a statement to FOX Business, a spokesperson for the company said it would “fully cooperate with the U.S. House Judiciary Committee investigation, including production of documents and witness testimony as required by the subpoena.”

The committee said it is conducting oversight into “how and to what extent foreign laws, regulations, and judicial orders are being used to discriminate against innovative American companies and infringe on the rights of U.S. citizens.” As part of that effort, the subpoena seeks communications between Coupang and South Korean authorities, along with testimony from company representatives.

According to the letter, the KFTC has subjected U.S. firms to “punitive obligations, excessive fines, and discriminatory enforcement practices." The letter also referenced recent regulatory actions involving Coupang, including scrutiny and potential penalties tied to a data-related incident, which the committee said exemplify broader concerns about how American-owned companies are treated under South Korean enforcement.

The investigation, they said, is intended to inform potential legislation aimed at protecting U.S. companies and citizens from what Congress describes as discriminatory foreign regulations and enforcement decisions.

Stellantis Shares Crash On 22 Billion Euro Charge Tied To Miscalculating EV Demand

Stellantis NV shares crashed the most on record in European trading after the automaker disclosed a 22-billion-euro (about $25 billion) charge tied to its failed EV strategy.  

Management framed the charge as the cost of misreading the slope of EV adoption, effectively building a product and investment plan around an "energy transition" timeline that outpaced customers' budgets.

"The reset we have announced today is part of the decisive process we started in 2025, to once again make our customers and their preferences our guiding star," Stellantis CEO Antonio Filosa wrote in a statement.

Filosa said, "The charges announced today largely reflect the cost of over-estimating the pace of the energy transition that distanced us from many car buyers' real-world needs, means and desires. They also reflect the impact of previous poor operational execution, the effects of which are being progressively addressed by our new Team."

The writedowns include roughly 6.5 billion euros in payments, mainly for supplier compensation, as the struggling maker of Jeep and Fiat cars cancels multiple EV models and significantly reduces its battery footprint amid weaker demand.

Stellantis is revising earlier targets for EV sales in Europe and for 50% EVs in the US by 2030, while also seeking to offset rising tariff costs.

Part of Filosa's "reset" includes $13 billion in US investment, delaying some EV plans, bringing back V8s to refresh the Ram lineup, and multiple Jeep launches and refreshes this year. He also scrapped investments tied to a planned hydrogen joint venture.

Stellantis is also exiting its Canadian battery joint venture with LG Energy Solution (LG is buying Stellantis's stake in the Windsor, Ontario, plant project).

The move by Stellantis mirrors moves by industry peers, including Ford Motor, General Motors, and others. On Thursday, Volvo Cars shares fell the most on record after earnings missed, with the company citing "a challenging external environment."

Stellantis shares in Milan fell as much as 24%, the most on record in Bloomberg data dating back to 2015.

Shares return to Covid-era lows.

Here's institutional commentary from UBS analyst Patrick Hummel:

Stellantis: 'Kitchen Sinking'; Shares Plunge 19%

Shares in Stellantis plunge 19% after the carmaker accompanied news of EV-related charges with soft 2026 guidance (in line on top-line, below on AOI and FCF). Stellantis announced €22 bn one-off charges in H2 2025, including €6.5 bn cash charges spread over four years. The latter is important, said UBS analyst Patrick Hummel, who thinks about €1.6 bn per annum cash outflows can be digested from a balance sheet perspective (€46 bn gross liquidity, €5 bn hybrid bond issue and no dividend for FY 2025 announced).

While Patrick thinks the one-offs are much larger than consensus expectations (€5-10 bn), the important aspect is the cash portion that is more in line. "Negative today, but it could be the clearing event we've been waiting for," he said, repeating his 'buy' rating on the shares.

The EV push by Western automakers has become an epic disaster, just as China is flooding Europe with low-priced EV models and eyeing the same playbook for Canada. In the US, Tesla remains the dominant outlier, continuing vehicle production while moving full steam ahead with robotaxi ambitions, AI stack, and robotics.

 

Pourquoi l'État profond cible-t-il avec une telle férocité la directrice du renseignement national, Tulsi Gabbard ?

Why Is The Deep State Targeting DNI Tulsi Gabbard With Such Ferocity?

Authored by Sundance via The Conservative Treehouse,

Each day more and more people are starting to realize/notice there are elements of the United States intelligence apparatus that are targeting Director of National Intelligence, Tulsi Gabbard.  The need for control is a reaction to fear, and Tulsi Gabbard has the DC Intelligence Community very worried.

What you will read below is something that was written back in 2024 about the potential for the Office of the Director of National Intelligence (ODNI), if President Trump were to win the election. Subsequently, he did win; and while we are not saying this is the exact ODNI script that is being followed, we are certainly not disputing that either.

Read the roadmap below –Written in 2024– compare it to current events and decide for yourself if this is something that rings a bell and may explain the IC apoplexy.

The ODNI was created as an outcome of the 9-11 Commission recommendations.  In the era shortly after 9/11, the DC national security apparatus was constructed to preserve continuity of government and simultaneously view all Americans as potential threats.

The Department of Homeland Security (DHS) and the Office of the Director of National Intelligence (ODNI) were created specifically for this purpose.

Washington DC created the modern national security apparatus immediately and hurriedly after 9/11/01.  DHS came along in 2002, and within the Intelligence Reform and Terrorism Prevention Act of 2004 the ODNI was formed. 

When Barack Obama and Eric Holder arrived a few years later, those newly formed institutions were viewed as opportunities to create a very specific national security apparatus that would focus almost exclusively against their political opposition.

Here is the weird part.  The ODNI was formed in 2004, with the intent for the office to be the pivot point of a national security radar. The DNI was intended to provide information to domestic agencies about foreign terror networks that would prevent something like 9-11 from happening again.  However, the Office of the Director of National Intelligence has never, not for one day, operated on this intent. This is why they are such a critical position from my perspective.

The office was new, not established yet as a functioning silo, when Barack Obama and Eric Holder arrived in 2009. They quickly dispatched an idiot, James Clapper, into the operation so they could weaponize around the offices’ fulcrum point.

Prior to the DNI office existing, the CIA radar would sweep externally and then report to the Office of the President. The DNI was intended to take external radar sweep (CIA) and make it a full 360° circle, adding a sweep inside the USA that would be handled by the Dept of Homeland Security.

The DHS sweep and the CIA sweep would then be combined into a central collection hub called the ODNI. Everyone with responsibility for “national security” could access the ODNI material. Essentially and presumably, post 9-11 nothing like jihadists practicing to fly airplanes would be missed again; at least that was the intent.

The weird part is that because the DNI was immediately weaponized, the office has never functioned to the purpose of its intent.

No one truly knows what the office possibilities consist of because no one has ever seen anyone try to functionally control the hub. If you think I’m joking about the intent of Obama and John Brennan using the DNI watch this video. This is before Brennan became CIA Director, this is when Brennan was helping Barack Obama put the pillars into place.

For the intents of this outline the takeaway is how the DNI office has never been used for good.  In a strategic way, that can be used to our advantage if you are talking about leveraging silos against each other.

Example:  The DNI can assemble material from any silo. Meaning the DNI can reach into any IC silo and extract anything they want. Under the original authorities given to the DNI, this authority exists. So, let’s spread the wings on this office and do exactly what it is permitted to do, only this time extract for the purpose of showing the President what is happening in every silo.

In essence, the DNI *CAN BE* deployed like a super strong cross-silo inspector general’s office. Force the other IC silos to comply with the demands of the DNI. This has never been done. But the DNI has this unique power.

The DNI can make the FBI, DOJ, DOJ-NSD, DoD, DoS and CIA provide anything and everything they demand.  Instead of the other silos using blocks and threats against the office of the President, use the authority of the DNI to get them without confrontation.   Then use the DNI to declassify the documents (if requested by potus), instead of the originating silo.

Can you see how the DNI office can be repurposed to be a seriously strong weapon in the toolbox of the President, against the schemes of those inside the various IC silos.

The DNI becomes much more important than the CIA Director, NSA Director, FBI Director, Attorney General, etc, because the DNI can just show up and say, “give me this.”  That’s the functional purpose of the DNI office that has never been exerted; let’s flippin’ use it.

Let’s use the office of the DNI as the central information hub that takes information from inside the corrupt silos, then provides that information to the President who puts sunlight upon it.  Each corrupt silo penetrated with disinfectant.  This could begin a process to pull down the shadow operations and let the American public see what has been happening inside our IC apparatus.

To accomplish this approach the National Security Advisor to the President (NSA) [currently Marco Rubio], would be the person who tells the DNI what they are looking for. How does the NSA know what to look for?  Because the National Security Advisor is the head of the National Security Council (NSC).

Let the NSC monitor the silos with specific intent, perhaps with assistance from open-source research, then provide Trump’s NatSec Advisor with details on what appears to be happening and where.   With the approval of the President, the NSA [Rubio], then turns to the DNI [Gabbard] and says, “POTUS wants this, go get this.”

Raw, unfiltered, unredacted information.   The silo administrators end up in a fight with the ODNI, not the office of President Trump.  President Trump then uses the power of his office to support the demands of the DNI.

Under this approach the DNI has a lot more power; yet funnily, it’s power they already have – yet have never utilized.

[END of Prior Outline]

Does any of that track with what we are currently experiencing?

With DNI Tulsi Gabbard putting strategic pressure from the inside, and We The People putting accountability pressure from the outside, this Deep State intelligence nut just might begin to crack.

In fact, I might even argue that cracking is exactly what we are starting to see.
