Does heatbed also solve warping of large pla objects?

Vertex 3D Printer Vertex - Issues while printing
1

Hi, I need to print regularly large objects (195100175mm) in PLA. SO in X-direction I dont have a lot of room for skirts. Known problem I have is warping of the object up to a point it can detach from the bed; which is a pitty for 27hrs prints

Whould simply installing a heatbed solve my problem? Any advice about type of heatbed?

[quote=“TLS”]Whould simply installing a heatbed solve my problem?[/quote]It will certainly lessen the risk of warping.

[quote=“TLS”]Any advice about type of heatbed?[/quote]You can use a MK3 (have a look in the [color=#408040]Wiki[/color]) or Marlak’s bed (240x215) : check [color=#408040]here[/color].

I see that the MK3 is 215215. The 8400 glassplate is 240215 if I’m not mistaken. How is the aluminium plate from the heatbed attached to the printer bed, the clips won’t work?

You need to insert an insulating layer between the bed and the alu plate. I’m using a sheet of cork.

With the MK3 heated alu plate, can you print ABS straight on the plate, or do you still need to apply kapton tape?

Anyone experience with the PETG filament?
It seems to have the advantages of PLA:

  • doesn’t shrink a lot
  • easy to print

what I find interesting is it appears to be very strong and hydrofobic so probably more durable than PLA. I want to print a manifold for dispersing mineral oil

You can print directly on the alu plate of the heatbed, but I use DimaFix to make it adhese even better.
