Kunt u een instrument niet vinden?

Zoek dan via de zogenaamde ISIN code. Elk instrument, aandeel etc. heeft een unieke code.

Kies vervolgens - wanneer er meerdere resultaten zijn - de notering op de beurs van uw keuze.

Waar vind ik die ISIN code?

Google de naam van het instrument, aandeel etc. met de toevoeging 'ISIN'.

Als zoeken op ISIN code geen resultaten oplevert hebben wij het instrument of aandeel niet in onze koersendatabase.

    Wanneer je kansen zoekt binnen de markt additive manufacturing, kan ik je deze tips geven:
    Beperkt je tot bedrijven die in een markt opereren waarbij het produkt niet of moeilijk op een andere manier geproduceerd kan worden. ( bv living tissue prinrting / complex metal printing).
    Prtotyping met plastics, maar wel tegen lage kosten, is ook een winstgevende markt.
    Toeleveranciers voor de markt van metal printing hebben ook bijzondere kansen omdat de grondstof aan zeer specifieke eisen moet voldoen, en daardoor extreem duur is.

    Enkele voorbeelden van koopbare bedrijven die goed opereren binnen deze markten:
    Materialise
    SLM Solutions
    ExOne
    ProtoLabs
    Pyrogenesis

    Stratasys zie ik nog steeds niet als kansrijke investering omdat de technology die zij in huis hebben eenvoudig nagemaakt kan worden door concurrerende bedrijven.

    Steel reinforced 3D prints with new Technique

    Continuing on the never-ending adventure of how to make a 3D print stronger, [Brauns CNC] is coming at us with a new technique that involves steel-reinforced 3D printed parts. We’ve seen plenty of methods to create stronger 3D prints, from using carbon fiber filament to simply printing the part in a way that the layers of the print are orthogonal to the direction of force. We’ve even seen casting carbon fiber bars into 3D prints, but of course that will only work with straight parts. [Brauns]’ technique uses steel wire, embedded into the print itself, and from some testing there’s about a 50% increase in strength of the part. The process of embedding a steel cable into a 3D printed part is simply taking apart the model and putting a channel in for the cable. At a specific layer height, the printer is stopped, the steel cable is embedded with the help of a soldering iron, and the printer continues doing its thing.

    There’s a slight amount of Gcode hacking to make this happen, and the process of embedding a steel cable into a print is a bit finicky. Still, if you want stronger 3D prints, there are worse ways to do it, and certainly less effective ways of doing it. You can check out the video for this technique below.

    3D Printed construction - Apis Cor, residential home in Russia

    All 3DP reported that Apis Cor is a San-Francisco-based start-up developing unique mobile construction 3D printers that print structural components (self-supporting walls and partitions). Like most, their concrete 3D printer uses material extrusion technology. They have developed their own material mix, which is an extrudable concrete consisting of cement, sand, geopolymers, and fibers. They prepare the final material mix by mixing the raw materials in a large hopper. This mix is then fed by a pump system to the extruder, which deposits the material.

    Their 3D printer has an independent robotic arm which prints the structural components on-site. They intentionally left a small gap between the interior and exterior of walls, where they placed fiberglass reinforcements and sprayed a polyurethane-based mixture for insulation. Once the walls were printed, they removed the printer with the help of a crane to install windows, appliances, and the roof. The entire structure took just 24 hours to complete.

    Material Mix: Concrete mix made out of cement, sand and other additives

    De markt rond Pyro is nog wat afwachtend, maar de potentie van het bedrijf is groot.
    Vier pijlers die allen afzonderlijk al een enorm potentieel hebben.
    Ik denk dat dit potentieel contract over TiAl poeder gaat daar er geen verdere investeringen nodig zijn (buiten één extra medewerker).
    Het wachten is op nieuws tot de levering van Drosrite systemen.
    De globale productie van staal neemt de laatste maanden weer toe, aluminium nog niet, maar dit zal niet lang op zich laten wachten.
    Ik denk zomaar dat de investeringsbereidheid bij de "smelters" met een maand of zes een stuk groter zal zijn dan op dit moment.

    Vind geen draadje over recycling/recycle aandelen

    money.usnews.com/investing/stocks/env...

    Interessante sector voor de toekomst.
    Now, with many of these companies in the beginning stages of operation, the question is how they can grow. “There are many that are operational, but they’re still in that early commercial stage,” says Martin. “So they’re proving out their models. And this is really an inflection point, because they’re at a stage where they need investment and partnerships that will ensure their success.”

    Partnerships and deals are happening quickly. Both Coke and PepsiCo have signed agreements to buy plastic from Loop Industries, a company that can turn old packaging, carpet, clothing, and even ocean waste into new plastic for use in bottles. Multiple brands have made commitments to start using much more recycled content in the packaging they produce; Evian announced in early 2018 that it would move to 100% recycled packaging by 2025. The challenge is having enough supply to meet that demand, and for that more investment is necessary.

    Toekomst HPQ veelbelovend:
    www.equityinsight.ca/Articles/30/

    HPQ has been trading in a tight range for almost 2 years as we concentrated on everything we have discussed today. With the amount of information and developments going forward, I think this will change.
    Heb je deze ook in de port? Nooit echt ingelezen. Veel in samenwerking met PYR.
