ABS filament is a flexible materials that is an ideal possibility for if you want your 3D-printed components to be robust and heat-resistant. Learn to print this materials like a Professional on this in-depth information.
What’s ABS filament? ABS is among the mostly used and versatile supplies accessible in 3D printing at this time. There are a number of further issues to think about when printing with ABS as in comparison with PLA, however the further hurdles are properly value it for the improved power, post-processing capabilities, and temperature resistance of ABS.
What’s ABS?
ABS or Acrylonitrile Butadiene Styrene is a typical thermoplastic. ABS filament is among the hottest kinds of 3D printing filament as a result of its versatility and power, and is usually used for injection molding and merchandise like Lego, devices, sports activities tools and extra.
Nice tasks for ABS:
- Automobile inside components – telephone mounts, cup holders

Getting that first layer proper
As with all 3D printing, getting the primary layer down is crucial 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 unhealthy in case you’re struggling to get good mattress leveling, everybody has to be taught it. If you happen to need assistance particularly on mattress leveling, try our article. Listed here are the important thing factors:
- You want the print mattress to be degree.
- If you happen to 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 right peak from the mattress. (Z-offset)
- If you happen to total first layer is equally too excessive or too low throughout your complete print, regulate your Z-Offset.
- You want an excellent adhesive to help your ABS in sticking to the mattress.
- And naturally, ensuring that your extruder/hotend is heated to the best temperature.

Greatest Mattress Setup for ABS
With a purpose to print with ABS, you want a headed mattress. The really helpful mattress temperature for ABS is 110°C. Most trendy 3D printers can attain this temperature, but when yours can’t, you need to have the ability to get away with 90°C.
Notice: If that is your first time having your print mattress this scorching, watch out as these temperatures can burn pores and skin in a short time!
The perfect construct floor for ABS is PEI, accessible both clean or with a powder coated floor for further mechanical adhesion. You may also print on glass with adhesion promoters like Magigoo or a typical 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 if you’re utilizing the identical construct plate as different supplies you possible won’t have to regulate this setting. Professional Tip: Your print mattress will likely be a barely totally different form when totally heated to ABS print temperatures, so all the time carry out your mattress leveling at temperature to get the most effective outcomes.
Enclose Your Printer for the Greatest Outcomes
The trick to have ABS components keep on the mattress throughout a print and never break 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 bear in mind to attain these objectives:
- 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 various totally enclosed 3D printers accessible at this time, along with enclosures accessible as equipment for a lot of machines that don’t come totally enclosed. Moreover, try our video under on constructing a customized, low-cost enclosure for any printer that may allow you to begin printing with ABS straight away.
In case your first layer just isn’t sticking:
- Be certain that the mattress is degree.
- Be certain that the mattress is scorching sufficient – we advocate 110°C.
- Guarantee that the ambient temperature of the print atmosphere isn’t too scorching or chilly (or else regulate accordingly).
- Be sure to put the adhesive on the mattress.
- Be certain that the print head is shut sufficient to make a pleasant first layer.
- Be sure to run the extruder sufficient earlier than your print begins so there may be filament going onto the mattress throughout your complete first layer. In MatterControl you possibly can add a skirt and calibrate how a lot materials you wish to extrude to make sure the hotend is totally primed.

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

Getting the temperature proper
When working with a brand new roll of filament for the primary time, we typically like to start out 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 power of the half to be in good stability with one another. This temperature vary is a generalization, so please reference the precise filament you’ve when growing your print settings.
FYI – there’s a temperature tower function construct into MatterControl so you possibly can create customized temperature towers to help in your print setting improvement.
What to search for
If the temperature is just too excessive:
You will note extra strings between the separate components of your print and chances are you’ll discover that the extruder leaks out quite a lot of plastic whereas shifting between separate areas of the print. If this occurs you need to attempt to incrementally decrease the temperature by 5 levels till the extruder just isn’t leaking a lot materials.
ABS being printed too scorching can produce a tough texture, in case your components 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 advocate you overview your retraction settings and presumably tune this particularly.
If the temperature is just too chilly:
You’ll both see that the filament just isn’t sticking to the earlier layer and you might be getting a tough floor, or you’re going to get a component that’s not robust and will be pulled aside simply. In both case, you need to enhance the temperature by 5 levels and take a look at once more till you get good line segments on each layer and have a robust half when carried out printing.
A print gone chilly. Examine 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 ahead 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 chances are you’ll must reverse the extruder.
- If you’re having hassle eradicating the filament, enhance the temperature to 180°C and take a look at once more.
- Clear the extruder gear and blow out any particles from the extruder entrance.
- Improve the warmth and cargo the brand new filament usually.
- Run the brand new coloration by the extruder till it runs clear and the brand new coloration is all that’s popping out of the extruder. If you’re switching from a darkish coloration (akin to black) to a lightweight coloration (like white or pure) chances are you’ll need to extrude for a couple of minutes to be you certain haven’t any darkish contamination.
- Print one thing that you do not care if it has bits of the earlier coloration 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 possibly can believe that there will not be darkish materials combined with lighter materials.
Notice: We really helpful eradicating the filament when tender somewhat than when totally melted so that there’s a decrease risk 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 arduous to scrub out. Mushy removing additionally helps be sure that you get all the pieces out of the extruder tip.
What to do if issues go unsuitable
There are a number of key issues to verify when your prints aren’t working. However earlier than we have a look at options we have to have a quick description of your signs.
“I am unable to get the primary layer to stay.”
- Be certain that the extruder is on the proper peak. Regulate the restrict swap or extruder to 0 peak
- Be certain that the print mattress is degree. Stage the mattress.
- Be sure to’re printing on the proper temperature and that your mattress is the best temperature.
- Examine the ambient temperature of your atmosphere. If it’s too chilly or too scorching exterior, your print can differ drastically!
“The half has unhealthy inner layers and prime surfaces.”
- Examine the extrusion temperature (chances are you’ll want to extend it by 5 diploma bumps).
- Examine the filament rigidity.
- Clear the filament drive gear.
- Lower your velocity.
- Be certain that your half is correctly cooled.
“The skin edges of my components have numerous little bumps on them.”
- Be certain that your printer is getting sufficient information. If printing from a pc, be sure that the pc just isn’t too busy to feed the printer instructions. If the printer is pausing it’s often because of the pc being too busy.
- Print from the SD card. On some printers you possibly can attempt to print from the SD card. This usually helps the printer have sufficient information to run extra easily.
Nonetheless, do not be too fast to imagine the issue is in your ABS. With the best settings and endurance hobbyists have succeeded in printing all kinds of supplies a lot of which have very low viscosity. It’s best to have the ability to get usable components 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 need to allow “Cooling” within the print settings.
- Get a small fan. In case your printer doesn’t have an built-in fan you need to look into getting a small desk fan. This may help 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 an excellent 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 scorching finish is getting scorching. Examine to verify the new finish is heating in any respect. If it’s not, you have to have your printer serviced. It’s possible that you’ve a unfastened connection, or your electronics have been fried (assuming the printer continues to be linked 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 be sure that we’ve correct rigidity in opposition to the filament. Often improper rigidity or a clogged drive gear will make the print look extra like the image we’ve for low temperature filament, but it surely typically 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 a small particle in your extruder tip jamming the plastic. Use the change filament method described above to drag out any particles which are within the extruder tip.
- Examine for and take away jams between the extruder and scorching 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 often on the junction between the extruder and scorching finish. Take off the extruder and take away all of the ABS you possibly can (chances are you’ll want the new finish scorching to get all the fabric out.) If you cannot get out all of the filament by pulling, chances are you’ll must attempt to drive it down by the new finish. We often use a small allen wrench. If this fails you possibly can attempt to drill out the extruder or scorching finish however chances are you’ll want to exchange components. Remember to take precautions in opposition to being shocked or burned. If you’re not certified to do that work, discover somebody who’s, somewhat than danger damage.
