ABS filament is a flexible materials that is an excellent possibility for whenever you want your 3D-printed elements to be sturdy and heat-resistant. Learn to print this materials like a Professional on this in-depth information.
What’s ABS filament? ABS is likely one of the mostly used and versatile supplies out there in 3D printing at present. There are just a few further issues to think about when printing with ABS as in comparison with PLA, however the further hurdles are properly price it for the improved energy, post-processing capabilities, and temperature resistance of ABS.
What’s ABS?
ABS or Acrylonitrile Butadiene Styrene is a typical thermoplastic. ABS filament is likely one of the hottest kinds of 3D printing filament attributable to its versatility and energy, and is usually used for injection molding and merchandise like Lego, devices, sports activities gear and extra.
Nice tasks for ABS:
- Automobile inside elements – telephone mounts, cup holders

Getting that first layer proper
As with all 3D printing, getting the primary layer down is a very powerful a part of the print. All the pieces else is constructed upon this (actually) and it is the place most new 3D printer customers have points honing their expertise. Do not feel dangerous when you’re struggling to get excellent mattress leveling, everybody has to be taught it. Should you need assistance particularly on mattress leveling, try our article. Listed here are the important thing factors:
- You want the print mattress to be degree.
- Should you see some areas of your first layer are too excessive whereas others are too low, re-do your mattress leveling.
- You want the extruder to be homed to the proper top from the mattress. (Z-offset)
- Should you complete first layer is equally too excessive or too low throughout all the print, regulate your Z-Offset.
- You want adhesive to help your ABS in sticking to the mattress.
- And naturally, ensuring that your extruder/hotend is heated to the correct temperature.

Finest Mattress Setup for ABS
In an effort to print with ABS, you want a headed mattress. The really useful mattress temperature for ABS is 110°C. Most trendy 3D printers can attain this temperature, but when yours can not, you must be capable to get away with 90°C.
Observe: If that is your first time having your print mattress this sizzling, watch out as these temperatures can burn pores and skin in a short time!
The most effective construct floor for ABS is PEI, out there both easy or with a powder coated floor for further mechanical adhesion. You too can print on glass with adhesion promoters like Magigoo or an ordinary glue stick.
As with all 3D printing, mattress leveling and Z-Offset are essential to success. ABS doesn’t have any particular wants for Z-Offset, so in case you are utilizing the identical construct plate as different supplies you probably won’t have to regulate this setting. Professional Tip: Your print mattress might be a barely completely different form when totally heated to ABS print temperatures, so at all times carry out your mattress leveling at temperature to get the perfect outcomes.
Enclose Your Printer for the Finest Outcomes
The trick to have ABS elements keep on the mattress throughout a print and never cut up after being printed is to permit the printed half cool as slowly as doable, and as uniformly as doable. Right here are some things to remember to realize these targets:
- Little to no layer cooling – begin together with your half cooling fan utterly off.
- Enclosed construct space – keep a secure and excessive ambient temperature round your half after it has been printed.
There are lots of totally enclosed 3D printers out there at present, along with enclosures out there as equipment for a lot of machines that don’t come totally enclosed. Moreover, try our video beneath on constructing a customized, low-cost enclosure for any printer that can allow you to begin printing with ABS straight away.
In case your first layer shouldn’t be sticking:
- Be certain that the mattress is degree.
- Be certain that the mattress is sizzling sufficient – we suggest 110°C.
- Be sure that the ambient temperature of the print atmosphere isn’t too sizzling or chilly (or else regulate accordingly).
- Be sure you put the adhesive on the mattress.
- Be certain that the print head is shut sufficient to make a pleasant first layer.
- Be sure you run the extruder sufficient earlier than your print begins so there’s filament going onto the mattress throughout all the first layer. In MatterControl you may add a skirt and calibrate how a lot materials you want to extrude to make sure the hotend is totally primed.

PEI is an effective way to print ABS. It makes an excellent shiny backside layer and the heated mattress ensures that your elements keep good and flat.

Getting the temperature proper
When working with a brand new roll of filament for the primary time, we usually like to begin out printing at about 230°C after which adjusting the temperature up or down by 5 diploma increments till we get the standard of the print and the energy of the half to be in good stability with one another. This temperature vary is a generalization, so please reference the precise filament you could have when growing your print settings.
FYI – there’s a temperature tower function construct into MatterControl so you may create customized temperature towers to assist in your print setting improvement.
What to search for
If the temperature is simply too excessive:
You will note extra strings between the separate elements of your print and you might discover that the extruder leaks out plenty of plastic whereas shifting between separate areas of the print. If this occurs you must attempt to incrementally decrease the temperature by 5 levels till the extruder shouldn’t be leaking a lot materials.
ABS being printed too sizzling can produce a tough texture, in case your elements really feel and/or look tough, attempt decreasing the temperature and see if that impact is diminished.
Typically you should have a cloth that’s merely much less viscous than ABS and can leak extra even at decrease temperatures. We suggest you evaluate your retraction settings and presumably tune this particularly.
If the temperature is simply too chilly:
You’ll both see that the filament shouldn’t be sticking to the earlier layer and you might be getting a tough floor, or you’re going to get an element that’s not sturdy and might be pulled aside simply. In both case, you must enhance the temperature by 5 levels and check out once more till you get good line segments on each layer and have a robust half when achieved printing.
A print gone chilly. Verify your retraction and warmth for clear prints.
Altering filament
When switching ABS colours:
- Whereas the extruder is chilly set the warmth to 120°C and look forward to it to warmth up.
- Whenever you attain 120°C take away the present filament from the extruder. You might be able to again it out by hand or you might have to reverse the extruder.
- If you’re having bother eradicating the filament, enhance the temperature to 180°C and check out once more.
- Clear the extruder gear and blow out any particles from the extruder entrance.
- Enhance the warmth and cargo the brand new filament usually.
- Run the brand new colour via the extruder till it runs clear and the brand new colour is all that’s popping out of the extruder. If you’re switching from a darkish colour (equivalent to black) to a lightweight colour (like white or pure) you might wish to extrude for a couple of minutes to be you positive haven’t any darkish contamination.
- Print one thing that you do not care if it has bits of the earlier colour in it, or run the extruder for a number of minutes. It could take as a lot as 10 to fifteen minutes of extrusion earlier than you may trust that there will not be darkish materials blended with lighter materials.
Observe: We really useful eradicating the filament when comfortable moderately than when totally melted so that there’s a decrease chance of depositing melted materials onto the extruder drive gear or leaving meterial excessive up the soften chamber entrance. Each of which may trigger jamming and are onerous to scrub out. Mushy elimination additionally helps make sure that you get every part out of the extruder tip.
What to do if issues go unsuitable
There are just a few key issues to verify when your prints aren’t working. However earlier than we take a look at options we have to have a short description of your signs.
“I am unable to get the primary layer to stay.”
- Be certain that the extruder is on the proper top. Alter the restrict change or extruder to 0 top
- Be certain that the print mattress is degree. Stage the mattress.
- Be sure you’re printing on the proper temperature and that your mattress is the correct temperature.
- Verify the ambient temperature of your atmosphere. If it’s too chilly or too sizzling exterior, your print can differ drastically!
“The half has dangerous inner layers and prime surfaces.”
- Verify the extrusion temperature (you might want to extend it by 5 diploma bumps).
- Verify the filament rigidity.
- Clear the filament drive gear.
- Lower your pace.
- Be certain that your half is correctly cooled.
“The surface edges of my elements have a number of little bumps on them.”
- Be certain that your printer is getting sufficient knowledge. If printing from a pc, make sure that the pc shouldn’t be too busy to feed the printer instructions. If the printer is pausing it’s normally as a result of pc being too busy.
- Print from the SD card. On some printers you may try to print from the SD card. This typically helps the printer have sufficient knowledge to run extra easily.
Nonetheless, do not be too fast to imagine the issue is in your ABS. With the correct settings and persistence hobbyists have succeeded in printing all types of supplies a lot of which have very low viscosity. It is best to be capable to get usable elements even with some decrease high quality filament.
“Tall sections of my prints look melted or squished collectively.”
- Activate “Cooling”. In case your printer has a fan you must allow “Cooling” within the print settings.
- Get a small fan. In case your printer doesn’t have an built-in fan you must look into getting a small desk fan. This can assist dramatically with tall sections of your print or when “bridging” (printing prime layers that span gaps).
My half is curling out of bed.”
- Just be sure you have quantity of adhesive on the mattress and that you just’re making use of a contemporary layer with each print. As well as, activate a brim. Having a brim that extends out a bit helps give the half a big base to work with, in addition to having extra to stick to.
“My printer won’t extrude any materials.”
- Be certain that your sizzling finish is getting sizzling. Verify to verify the recent finish is heating in any respect. If it’s not, you’ll want to have your printer serviced. It’s probably that you’ve got a unfastened connection, or your electronics have been fried (assuming the printer remains to be related and responding to your host software program).
- Clear the drive gear and regulate rigidity. The very first thing we’re going to do is clear the filament touching drive gear and make sure that now we have correct rigidity in opposition to the filament. Normally improper rigidity or a clogged drive gear will make the print look extra like the image now we have for low temperature filament, nevertheless it generally does stop extrusion all collectively. Clear the pinch wheel with a wire brush, and ensure your rigidity is sweet and stable (an excessive amount of can even stop extrusion and is extra frequent with direct drives [the motor is directly connected to the drive gear] however much less frequent with geared drives).
- Take away the present filament. It could be that you’ve got a small particle in your extruder tip jamming the plastic. Use the change filament approach described above to drag out any particles which might be within the extruder tip.
- Verify for and take away jams between the extruder and sizzling finish. That is probably the most excessive kind of downside as a result of now it is time to take issues aside. Typically warmth can creep up the filament within the extruder and trigger a bulge that then cools and prevents any additional extrusion. That is normally on the junction between the extruder and sizzling finish. Take off the extruder and take away all of the ABS you may (you might want the recent finish sizzling to get all the fabric out.) If you cannot get out all of the filament by pulling, you might have to try to drive it down via the recent finish. We normally use a small allen wrench. If this fails you may try to drill out the extruder or sizzling finish however you might want to exchange elements. You’ll want to take precautions in opposition to being shocked or burned. If you’re not certified to do that work, discover somebody who’s, moderately than danger damage.
