Best settings for maximize strengh in ABS

Recommended Posts

Hi!

I'm trying to print a big box (185x185x110) and i would like to get it strong (it's for a portable amp) after a lot of dissapointments, frustations and so on i'm improving a bit step by step, i turn to ABS, hot bed, heat chamber (printing at 62 +-2 degrees) update the nozzle (0.7mm). But i'm not getting it, maybe what i want is not posible, i don't know. For a not too high parts (up to 20mm) even big ones i'm getting zero warping and nice finishing, but printing this box i'm getting nothing but head ache. (Few warping, but i can manage it, but some delamination

So, i'm wonder witch are theoretically best settings to get the stronger part possible.

I guess:

- big layers (i'm printing now at 0.25, i don't know how much could i print with 0.7 nozzle)

- slow (printing now at 40mm/s)

But what about temperature? It's better to print as cold as possible or hot?

I mean, is better print at 235ºC 40mm/s or 260ºC 40mm/s? colder means less shrinking but maybe hotter stick better with the previous layer...

Thanks.

I'm having the same problem. I can get it to stick with the use of gluestick. I think 235ºC isn't enough to get layers sticking though. Possibly using less fan might help, though it can get ugly if you have overhangs and bridges and top skins. Hopefully Joergen or calinb can chime in, they both have much experience with ABS but not sure about big ABS prints though.

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "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.
