ColorFabb XT Clear, auto-adherence problem

Recommended Posts

I have tried the Colorfabb XT Clear filament.

Until now I am getting disappointing results. :-(

Major problem I have found is auto-adherence being very low.

First layer sticks fine to the platform, using an adhesive, but any other layer on top does not adhere to the previous layer.

I have tried different temperatures, from 200 to 230 (220 is recommended by Colorfabb).

have tried with different layer thickness from 0,200 to 0,060. Colorfabb recommends 0,2 layers or above.

Speed set from 30 to 40.

Tested Infill, from 20% to 80%.

All I get is a mess of filament over the first bottom layers as there is no adherence at all.

Am I missing any factor ?

I have already used nGen Black. I can get amazing detailed parts with this filament. It is pretty consistent at a large range of temperatures.

For some parts I dont want the high polished finish of nGen, and have used Tamiya TS80 "Flat Clear" to apply a matte finish, with success.

nGen is one of the best general purpose filaments I have tried lately,

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
