Hi guys,

Can anyone recommend me an alternative to techABS that is like the techABS that used to be available?  (and not TitanX).

On my last 90m of natural techABS & it prints like a dream!  So I bought some TitanX black a couple of week ago, and have now done a few prints with it, i'm just not digging it.  It's not as nice or strong or bendy. Lay adhesion seems less too. Doesn't play that nice with acetone, infact when brushing with acetone I get loads of gritty bits coming off from the surface of the prints and the brush. Also now reading about TitanX clogging nozzles puts me off somewhat too -:(

[CEL got any techABS laying around you want to sell me?]

thanks Jay

@james-hollingdale TitanX is not compatible with acetone. This is pretty clear in the instructions from FormFutura. 

I have used a huge amount of TitanX and haven't seen any issues with it, but I print it at 245 instead of the 235 that most ABS profiles are set with the Robox. You may find this gives better layer adhesion. 

I haven't had a single nozzle clogged with any of the materials I use and I have printed thousands of hours. Clogged nozzles are due to poor maintenance. I purge TitanX every 10-20 hours just as with every ABS to keep the material in the unused nozzle from baking. This is required with all materials, but PLA and ABS need purging more often, every 10-20 hours in most cases. 

I don't have any suggestions for the TechABS.

That's interesting about the Acetone.  I wonder what the balance is of the abs / additives to make them say that.  The Acetone does definitely melt the surface when i tried, the gritty bits come as you rub or if you start stroking the surface with the brush bristles.  I'll ty with some other solvents i've got handy like MEK & Toluene.   It's a little annoying as acetone is dirt cheap & well handy to fuse bond abs parts together.

About the clogging though that's good news.  

Interestingly on my robox dual, latest automaker, the titanx black profile prints the first layer at 250, then drops back to 240 for the rest of the print.You think it's worth me tweaking it to 245 for the major part of the print?

@james-hollingdale You can certainly try adjusting the temperature. I used TitanX about a year before anyone else with the Robox so I always ran it a little hot. I do find that I prefer my own profiles more than the Robox profiles.
