Mattress adhesion is likely one of the most vital components for getting a very good 3D print. (For extra details about printing with ABS, like ideas and methods for achievement, take a look at our different article right here.)
A 3D printer with a heated mattress is required for efficiently printing with ABS filament as a result of ABS plastic shrinks when cooling. With no heated mattress, the underside of your print will cool at a special fee than the remainder of your ABS print, leading to dreaded ABS warp. The next information might help you produce completely flat, warp-free ABS prints on just about any 3D printer:
Tip 1: ABS would not adhere nicely to reveal 3D printer heated mattress glass.
Whilst you can usually get ABS to stick to reveal, heated borosilicate glass construct plates, the method is tough and you’ll greater than possible expertise warping/curling or failed prints because of the print breaking free from the glass mid-print.
Tip 2: ABS ought to NEVER be cooled with a layer fan.
In case you have an element that will get mushy/blobby due to an excessive amount of residual warmth, attempt printing two of them at a time. It will enable the primary half to chill whereas the second half is printing and vice versa. The simplest resolution is inside MatterControl (our unimaginable, community-driven, free 3D printing software program – yep, it’s very free). Just a few simple slice settings will let you require layer occasions to be not less than (X) quantity of seconds. If that is nonetheless not sufficient cooling time, you may specify the recent finish to maneuver off the print for a set period of time after every layer, after which resume printing the subsequent layer. These settings may be seen within the picture beneath:

Simply bear in mind, cooling followers and ABS will not be mates!
And on that very same notice, make sure that there’s not an Air Conditioner or every other compelled air disturbing the print space of your 3D printer surroundings; this could have the identical warping or splitting impact as a layer cooling fan when 3D printing with ABS filament.
Tip 3: Your 3D printer heated mattress ought to at all times be on.
Relying on the half and mattress adhesion methodology you are utilizing, 85-90°C is often an sufficient temperature vary on your 3D printer heated mattress when printing with ABS filament. You need to by no means exceed 120°C.
A Few ABS Mattress Adhesion Options:
So as of finest (strongest adhesion) to worst (weakest adhesion).
A) PEI Sheets, PET sheets, or Kapton tape on the 3D printer heated mattress with ABS Juice.
We made a easy, quick video on learn how to apply PET tape to your 3D printer glass mattress.
ABS Juice (or ABS Glue) is dissolved ABS filament in acetone. Begin with 2-3oz of acetone and 6-7 inches of ABS 3D printing filament, then regulate as wanted. Extra ABS plastic dissolved within the acetone equals higher mattress adhesion. The best consistency is thicker than water however thinner than milk. In case your combination is just too thick – like paste or yogurt – simply add some extra acetone to dilute.
Apply the ABS Juice to the 3D construct plate utilizing a brush when the mattress is sizzling. You will note the acetone evaporate and the mattress floor turn out to be dry slightly shortly.
Professional Tip: Pure ABS filament is essentially the most handy for making ABS Juice as a result of it is not going to depart any coloration in your prints. Do not forget that if you’re printing in Pink ABS and use Black Juice, the underside of your print might be black and crimson because the plastic extrudes over the skinny layer of black.
B) ABS Juice instantly on the 3D printer heated mattress’s glass. Identical as above, simply with out the PET or Kapton tape. Works very nicely and makes cleanup a bit simpler.
C) Glue stick. Just about any PVA primarily based glue stick works (Elmer’s, Scotch, UHU, and so forth). Apply a skinny layer of glue to a cool 3D print mattress in one route, after which apply one other layer in the other way (consider a crosshatch sample). Then deliver mattress as much as temp enable the glue to dry earlier than printing. PVA is water soluble so you may take away the skinny movie from the 3D printed half by rinsing with water. Use a moist paper towel to evenly redistribute the PVA glue stick movie on the mattress.
D) Hairspray. We use Aquanet’s unscented, additional tremendous maintain – it really works nicely, and it is fairly low-cost. Spray a skinny coat on a cool 3D construct plate, let it dry, then spray one other skinny coat, let it dry, deliver it as much as temp after which print. This the weakest maintain – however is the simplest to do and never a nasty place to start out when starting with printing ABS filament on a 3D printer with a heated mattress.
Professional Tip: Scented Hairsprays do work completely effective, however they may depart you with a really smelly 3D printing room – and possibly not in a great way.
Tip 4: The footprint of your half performs a HUGE function in mattress adhesion.
The larger and thicker the footprint/base of your 3D printed half, the extra warping forces current. We use hairspray efficiently for lots of our ABS prints, however prints with very giant footprints – like a pyramid – usually require stronger adhesion to remain firmly in place. The nearer the prints are to the middle of the print mattress (the place it is usually hottest) the higher.
Footprint instance:
Pyramid = giant footprint and extra tendency to warp.
Inverted pyramid = small footprint and fewer tendency to warp.
Bear in mind, ABS Juice may be very simply the very best methodology of mattress adhesion for ABS prints, however additionally it is the most important ache for each clean-up and for print elimination. An excessive amount of ABS Juice (or too thick a focus) may result in you breaking your glass making an attempt to take away the half.
Tip 5: Infill performs an enormous function in 3D printed ABS elements.
Too many strong layers on the underside adopted by gentle infill (<15%) will improve your probabilities of warp. Fast adjustments of infill density will trigger the print to chill in a different way and result in warp. Use the least quantity of strong layers potential to keep away from warping. Usually, the extra infill you employ, the extra warping forces you introduce to your 3D half. To additional perceive slice settings we now have a 3 half collection you might need to take a look at as a information.
We have 3D printed hundreds of issues in ABS filament and located we may forestall warping each single time by following some or all of the following tips.
Glad Warp-Free Printing!
