Impossible to fix warping w/ PLA?!

Recommended Posts

For the past month I have been fighting warping on my Ultimaker 2+, no matter what I try I cannot get a print larger than 2x2" to not warp.

It hasn't always been this way, but it feels like it's been a while since I've had a warp free print!

Any idea how to fix this?

Things I've already tried:

 

  • Blue painters tape - Heated bed turned off
  • Hairspray
  • Glue Stick
  • Clean glass build plate

 

I've tried the above (With the exception of the painters tape) with the following settings & techniques:

 

  • Printing with a large brim (8mm+)
  • 50c 55c60c 65c 70c heated bed
  • 205c 210c 215c 220c 225c 230c Nozzle temp
  • Creating an enclosure for the Ultimaker to prevent draft and retain heat
  • Turning off the fans for the entire print
  • Printing at higher temperatures on the bed & nozzle for the first few layers, then lowering the temp on bed and nozzle
  • Increasing layer thickness to .3mm and line width up to 120

 

My most common settings are .4mm nozzle printing at 1mm layer height using Cura 15.04.6 & 2.1.2

Maybe this can also serve as a guide to anyone who is having the same problem.

What PLA brand? Did you tried raising the print temp of the first layer?

Also, do you have anyway to measure the bed temp? If you use an infrared thingy try to place a bit of bluetape on the area so it can measure it.

I had a bad bed glass (died over 1 year of abuses and pulling too soon) but with hairspray applied while cleaning with windowcleaner I was able to use it, until I changed it for a brand new and for common pla I don't need anything except the bed to be clean.

      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.
