UM2 Heater Blocks

[shurik 87]

My UM2 is soon going to turn 6 years old and it is unbelievable machine.

Olsson block was installed once it got released, way, way back. It's parts show the age and wear and tear, so I am thinking of replacing/upgrading it.

There are some options on 3dsolex site and an advise would be appreciated.

Should I go for a new original Olsson block? Or to buy Matchless one? What benefit if any would it do?

Maybe, there other quality nozzle/PTFE suppliers out there? After all, brass nozzles and Teflon insulators from 3dsolex do not last as long as I would wish them to be.

And if asking - what fan shroud would you recommend to replace the original one?

Many ways to go - would appreciate your opinions.

OK, let's ask simpler question - does anyone use Matchless block and can recommend it?

Theoretically you should be able to print faster with the Matchless block, because the heat conductivity is increased. But the difference is relatively small in practice and you won't notice it. So I would take the Olsson block again and the extra price of matchless is just not worth it. On the other hand, you don't do anything wrong with the Matchless block.

 

I can recommend the fan shroud by Labern:

Be aware that most fan shrouds are made for the Olsson Block, I don't know it they fit also the Matchless block.

That's kind of reply I was hoping for, much appreciated.
