Delamination and Raft liftup

Good day @Zortrax,

The failed print (pic attached) is a hollow half sphere for a speaker pod (to be patented)

All prints have been in Z-ABS

I have gone through an entire spool of Z-ABS in attempting to debug this print

The front left corner’s raft lifts up & the rear left delaminates/fails to print after about 1” of height.

The latest failure was after

1 – cleaned plate & nozzle

2 – fresh abs juice

3 – fresh calibration

4 – fresh Z-ABS

I am willing to use a different material if appropriate (although I am fond of the Z-ABS & its cost).

Thoughts?

Thank you ahead of time!

PLA probably won't warp or split.  I also have problems with Z-ABS warping and am in the midst of making an enclosure for my M-200.

For such large models, make sure that there are no drafts and maintain a stable and high temperature in the chamber.

You may also use more ABS Juice. Eventually, use a material with lower shrinkage rate than Z-ABS.

Thanks MichaelHenry and Marek.

The printer is in a purpose built cabinet cabinet (clear windowed front with minimal ventilation) in an interior walk in closet. Drafts are a non issue.

Are all of the m200 listed on the m200 https://support.zortrax.com/printing-materials-overview/usable on the various m200 revisions?

For example, pla looks like a great option until I look further on the forum and see it has special hardware requirements http://forum.zortrax.com/index.php?/topic/3251-z-pla-pro-printer-is-loosing-steps-on-the-first-layer-of-the-raft/#entry33219

@Zortrax @Marek

Looking all over the website, it appears that either PLA PRO or HIPS are appropriate for low shrinkage large sized prints on the m200

  1. What is the shrinkage rate of HIPS vs PLA PRO vs ABS?
  2. Can the same hotend that has been used with ABS be used for HIPS?  Any special treatment between swaps recommended if so?
  3. How will PLA PRO hold up in a home environment when used as an audio cabinet over the long term?
  4. As PLA PRO is biodegradable… what causes the plastic to begin breaking down and loosing strength – and how quickly does this occur?
  5. What post processing options does PLA PRO accept?
  6. What is the cost of a dedicated hotend?
  7. Do any print speed implications exist due to the higher viscosity of PLA PRO when compared to HIPS?

$21 Z-ABS – High Shrinkage (Acetone & Mechanical post processing, Inexpensive)

$55 Z-PLA PRO – VERY low Shrinkage (Mechanical post processing only).  Deforms at 120*F.  Requires a fully separate hotend from other materials,  must always eject material between prints, print in a room that is 77* or lower, and remove printers side panels as per https://support.zortrax.com/tips-for-printing-with-z-pla-pro/

$50 Z-HIPS – Low Shrinkage (Limonene & Mechanical post processing), high durability & impact resistance

Thank you!

PETG might have a lesser tendency to warp than HIPS.

Hi Chris,

Actually, Z-PLA Pro has the lowest shrinkage rate among the mentioned materials. In most cases, it does not shrink at all. We recommend to use separate, dedicated v2 hotend for printing with Z-PLA Pro, you can find it in our store: https://store.zortrax.com/

Detailed information about Z-PLA Pro may be found here (Technical Data Sheet & Safety Data Sheet might be useful): https://zortrax.com/filaments/z-pla/

I guess Z-PLA Pro won’t fail as an audio cabinet. Anyway, for functional and end-use parts, I’d rather use Z-HIPS.

Regarding the Z-ABS and Z-HIPS - yes, the same hotend may be used and there is no special treatment while using these materials.

“for functional and end-use parts, I’d rather use Z-HIPS”

Z-HIPS ordered. These are the answers I required. Thank you greatly!

Marek - do you recommend using separate hot ends for PLA and ABS or can the same hote end be used for all Zortrax filaments?

The same hotend may be used for all Zortrax materials except Z-PLA Pro. Z-PLA Pro requires a separate hotend dedicated only for printing with that material: https://support.zortrax.com/tips-for-printing-with-z-pla-pro/

Z-PETG and Z-GLASS require some kind of a “special treatment” (https://support.zortrax.com/printing-tips-m200/), but separate hotend is not needed.

Thanks Marek.

I enclosed my v2 M200 and larger footprint ABS prints seem to be coming out with less warpage now.
