Will have to try harder to find the LRC in Aus, it sounds great. 

If your parts have tight bends, sf with the smaller cells seems to be the better choice.

Awesome info, thanks.  Most of my parts have compound curves, tight bends and are >3mm thick hence the soric.  Just thought I'd try the XF for a change. Might have a play with the low resin stuff.

R-g has soric lrc in stock. I allmost exclusively use lrc as sandwich core, as I am infusion allmost all of my parts. The traditional soric variants are to heavy for my applications. I've tried a lot of sandwich materials, but since I tried lrc, it is hard to find reasons to use anything else. Allmost as low in density as 3d core (less than 5% difference in my tests), allmost the same propertys of the finished part, but much, much more pliable an less expensive. And less printthrough. A 100g biaxial cloth between core and surface layer is enough to get perfect results. You can't get it around corners less than r50mm (the 1,5mm version) and it's not perfect for heavily convex or concave parts (you won't be able to get it at the surface of a sitting ball without cutting it). If the part has some straight parts and weight is very critical, I use drilled and groved foam, wich results in a significant weight difference.

Magic! Just used XF for a car seat (lotus derivative).  Worked nicely.  I have a contact at lantor, I'll ask about those other cores.

Virtually exactly the same as each other. The SF is ideal for thinner laminates, the XF comes in thicker sizes and so can be used to make thicker laminates. Both have the same resin uptake. Both will print a bit, but I find the effect can be slightly worse with the XF due to the bigger resin channels. Probably the biggest difference is flow speed if being used as an infusion medium, again due to the channel size. The XF flows faster than the SF, making it more suitable for application in larger infusions. 

Morning folks.  I've just bought some soric XF to have a play with.  It has larger cells than the SF variant so I was expecting it to be lighter overall but the resin channels are also larger so I expect it's not going to be any lighter.  Has anyone run a back to back comparison of the two looking at weight and part rigidity?  I'm curious to see what everyone else makes of it.
