ABS filament is a flexible materials that is an awesome possibility for while you want your 3D-printed elements to be robust and heat-resistant. Discover ways to print this materials like a Professional on this in-depth information.
What’s ABS filament? ABS is without doubt one of the mostly used and versatile supplies obtainable in 3D printing right this moment. There are a couple of additional issues to contemplate when printing with ABS as in comparison with PLA, however the additional 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 without doubt one of the hottest varieties of 3D printing filament resulting from its versatility and energy, and is usually used for injection molding and merchandise like Lego, devices, sports activities tools and extra.
Nice initiatives for ABS:

Getting that first layer proper
As with all 3D printing, getting the primary layer down is crucial a part of the print. The whole lot else is constructed upon this (actually) and it is the place most new 3D printer customers have points honing their abilities. Do not feel unhealthy should you’re struggling to get good mattress leveling, everybody has to study it. In the event you need assistance particularly on mattress leveling, take a look at our article. Listed below are the important thing factors:
- You want the print mattress to be stage.
- In the event 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 right peak from the mattress. (Z-offset)
- In the event you complete first layer is equally too excessive or too low throughout the complete print, alter 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.

Greatest Mattress Setup for ABS
As a way 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, it is best to have the ability to get away with 90°C.
Word: 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 most effective construct floor for ABS is PEI, obtainable both easy or with a powder coated floor for additional mechanical adhesion. You may as well 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 doubtless won’t have to regulate this setting. Professional Tip: Your print mattress can be a barely totally different form when absolutely heated to ABS print temperatures, so at all times carry out your mattress leveling at temperature to get one of the best outcomes.
Enclose Your Printer for the Greatest 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 potential, and as uniformly as potential. Right here are some things to remember to attain these objectives:
- Little to no layer cooling – begin together with your half cooling fan fully off.
- Enclosed construct space – keep a steady and excessive ambient temperature round your half after it has been printed.
There are various absolutely enclosed 3D printers obtainable right this moment, along with enclosures obtainable as equipment for a lot of machines that don’t come absolutely enclosed. Moreover, take a look at our video beneath on constructing a customized, low-cost enclosure for any printer that can allow you to begin printing with ABS immediately.
In case your first layer isn’t sticking:
- Ensure the mattress is stage.
- Ensure the mattress is scorching sufficient – we advocate 110°C.
- Make it possible for the ambient temperature of the print setting isn’t too scorching or chilly (or else alter accordingly).
- Be sure to put the adhesive on the mattress.
- Ensure 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’s filament going onto the mattress throughout the complete first layer. In MatterControl you may add a skirt and calibrate how a lot materials you wish to extrude to make sure the hotend is absolutely primed.

PEI is an effective way to print ABS. It makes an awesome 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 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 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’ve gotten when growing your print settings.
FYI – there’s a temperature tower function construct into MatterControl so you may create customized temperature towers to help in your print setting growth.
What to search for
If the temperature is simply too excessive:
You will note extra strings between the separate elements of your print and chances are you’ll discover that the extruder leaks out a number of plastic whereas transferring between separate areas of the print. If this occurs it is best to attempt to incrementally decrease the temperature by 5 levels till the extruder isn’t leaking a lot materials.
ABS being printed too scorching can produce a tough texture, in case your elements really feel and/or look tough, attempt reducing the temperature and see if that impact is lowered.
Typically you’ll have a cloth that’s merely much less viscous than ABS and can leak extra even at decrease temperatures. We advocate you evaluate your retraction settings and presumably tune this particularly.
If the temperature is simply too chilly:
You’ll both see that the filament isn’t sticking to the earlier layer and you might be getting a tough floor, or you’ll get an element that’s not robust and could be pulled aside simply. In both case, it is best to improve the temperature by 5 levels and check out once more till you get good line segments on each layer and have a powerful half when finished printing.
A print gone chilly. Test 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 could possibly again it out by hand or chances are you’ll must reverse the extruder.
- If you’re having bother eradicating the filament, improve the temperature to 180°C and check out 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 via 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 (resembling black) to a lightweight coloration (like white or pure) chances are you’ll 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 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 may have faith that there will not be darkish materials combined with lighter materials.
Word: We really useful eradicating the filament when smooth quite than when absolutely 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 exhausting to wash out. Gentle removing additionally helps make sure that you get all the pieces out of the extruder tip.
What to do if issues go unsuitable
There are a couple of key issues to examine when your prints aren’t working. However earlier than we take a look at options we have to have a quick description of your signs.
“I am unable to get the primary layer to stay.”
- Ensure the extruder is on the proper peak. Regulate the restrict swap or extruder to 0 peak
- Ensure the print mattress is stage. Stage the mattress.
- Be sure to’re printing on the proper temperature and that your mattress is the correct temperature.
- Test the ambient temperature of your setting. If it’s too chilly or too scorching exterior, your print can range drastically!
“The half has unhealthy inner layers and high surfaces.”
- Test the extrusion temperature (chances are you’ll want to extend it by 5 diploma bumps).
- Test the filament rigidity.
- Clear the filament drive gear.
- Lower your pace.
- Ensure your half is correctly cooled.
“The skin edges of my elements have a number of little bumps on them.”
- Ensure your printer is getting sufficient knowledge. If printing from a pc, make sure that the pc isn’t too busy to feed the printer instructions. If the printer is pausing it’s normally as a result of laptop being too busy.
- Print from the SD card. On some printers you may try to print from the SD card. This usually helps the printer have sufficient knowledge to run extra easily.
Nevertheless, do not be too fast to imagine the issue is in your ABS. With the correct settings and endurance hobbyists have succeeded in printing all kinds of supplies lots of which have very low viscosity. It is best to have the ability 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 it is best to allow “Cooling” within the print settings.
- Get a small fan. In case your printer doesn’t have an built-in fan it is best to look into getting a small desk fan. This will help dramatically with tall sections of your print or when “bridging” (printing high layers that span gaps).
My half is curling away from bed.”
- Just be sure you have quantity of adhesive on the mattress and that you just’re making use of a recent 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.”
- Ensure your scorching finish is getting scorching. Test to verify the recent finish is heating in any respect. If it isn’t, it is advisable to have your printer serviced. It’s doubtless that you’ve a free 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 alter rigidity. The very first thing we’re going to do is clear the filament touching drive gear and make sure that we’ve got correct rigidity towards the filament. Often improper rigidity or a clogged drive gear will make the print look extra like the image we’ve got 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 also can 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 tug out any particles which might be within the extruder tip.
- Test for and take away jams between the extruder and scorching finish. That is essentially the most excessive sort of drawback 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 scorching finish. Take off the extruder and take away all of the ABS you may (chances are you’ll want the recent finish scorching to get all the fabric out.) If you cannot get out all of the filament by pulling, chances are you’ll must 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 scorching finish however chances are you’ll want to interchange elements. You’ll want to take precautions towards being shocked or burned. If you’re not certified to do that work, discover somebody who’s, quite than danger harm.
