    Hi all!!
    I am so glad that I found you on the internet and really hope you can answer my question. I have an Asiga Pico 3D printer and everything about it is super-cool except….the resin. It is extremely expensive – approx. $500 for 500ml. The thing is it’s not very „stable“ and tends to separate rather quickly. What I want to know is do these resins really have a „shelf-life“ or can one just mix it up good again to re-use? I live in South Africa and am not sure who I can contact about trying to get the resin at a more reasonable price.
    I would appreciate any and all advice you can offer. ( If possible would you reply directly to my email address?)
    Best regards,
    Sandra

    Hi Sandra,
    your printer works with an UV led and either an dlp or a lcos chip on the inside. I couldn’t find detailed specs (asiga.com is down also), but standard dlp and lcos panels have a short lifetime exposed to radiation much lower than 405nm, so it’s probably somewhere round 405nm or possibly higher (up to 445nm). Therefore I doubt that the Buck Mix (cures <370nm) described here will work for you, but personally I wouldn't doubt so much until I tried (i.e. the LED in your device could also have a shorter wave length + non-standard imaging chip). Other than mixing your own, you can also purchase off-the-shelf polymers from spot-a-materials.com (tested up to 425nm, a bit more expensive, fair international shipping conditions) or from our US-pendant bucktownpolymers.com (almost all wavelengths, including 440nm and higher available, bit cheaper for large volumes, but international shipping conditions = nightmare). Btw, this is not sponsored information, all based on personal research and experience.
    Kind regards,

    Hey,

    weißt du, wie man ein gummiähnliches resin mischt?

      Hey!

      Damit habe keine praktische Erfahrung, weswegen ich dir da keine konkrete Emfehlung geben kann. Letztendlich benötigst du aber nur – statt z.B. dem 1,6-Hexanediol Diacrylat – ein Oligomer mit den gewünschten Eigenschaften. Die Polymerisation über den PI läuft genau so ab wie bei einem anderen Oligo- oder Monomer.

      Viele Grüße,
      Bucks
