ABS filament is a flexible materials that is a fantastic choice 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 among the mostly used and versatile supplies obtainable in 3D printing as we speak. There are just a few additional issues to contemplate when printing with ABS as in comparison with PLA, however the additional hurdles are effectively price it for the improved power, post-processing capabilities, and temperature resistance of ABS.
What’s ABS?
ABS or Acrylonitrile Butadiene Styrene is a standard thermoplastic. ABS filament is among the hottest sorts of 3D printing filament as a result of its versatility and power, and is commonly used for injection molding and merchandise like Lego, devices, sports activities tools and extra.

Getting that first layer proper
As with all 3D printing, getting the primary layer down is a very powerful a part of the print. Every part 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. In case you need assistance particularly on mattress leveling, take a look at our article. Listed here are the important thing factors:
- You want the print mattress to be stage.
- In case 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 top from the mattress. (Z-offset)
- In case you complete first layer is equally too excessive or too low throughout the whole print, alter your Z-Offset.
- You want a great adhesive to help your ABS in sticking to the mattress.
- And naturally, ensuring that your extruder/hotend is heated to the suitable temperature.

Finest Mattress Setup for ABS
With a view to print with ABS, you want a headed mattress. The beneficial mattress temperature for ABS is 110°C. Most fashionable 3D printers can attain this temperature, but when yours can’t, you must be capable of get away with 90°C.
Be aware: 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!
One of the best construct floor for ABS is PEI, obtainable both easy or with a powder coated floor for additional mechanical adhesion. You can even 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 in case you are utilizing the identical construct plate as different supplies you seemingly 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 all the time carry out your mattress leveling at temperature to get one of the best outcomes.
Enclose Your Printer for the Finest Outcomes
The trick to have ABS elements 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 realize these targets:
- Little to no layer cooling – begin together with your half cooling fan fully off.
- Enclosed construct space – preserve a secure and excessive ambient temperature round your half after it has been printed.
There are numerous totally enclosed 3D printers obtainable as we speak, along with enclosures obtainable as equipment for a lot of machines that don’t come totally 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 straight away.
In case your first layer shouldn’t be sticking:
- Make certain the mattress is stage.
- Make certain the mattress is sizzling sufficient – we advocate 110°C.
- Make it possible for the ambient temperature of the print atmosphere isn’t too sizzling or chilly (or else alter accordingly).
- Be sure to put the adhesive on the mattress.
- Make certain 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 the whole first layer. In MatterControl you’ll be able to 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 a fantastic shiny backside layer and the heated mattress ensures that your elements keep good and flat.
For extra in depth info concerning ABS mattress adhesion take a look at this text we wrote for extra detailed steering.
Getting the temperature proper
When working with a brand new roll of filament for the primary time, we usually 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 creating your print settings.
FYI – there’s a temperature tower characteristic construct into MatterControl so you’ll be able to create customized temperature towers to help 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 it’s possible you’ll 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 advocate you assessment 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’re 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 must 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 executed 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.
- While you attain 120°C take away the present filament from the extruder. You might be able to again it out by hand or it’s possible 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 shade by the extruder till it runs clear and the brand new shade is all that’s popping out of the extruder. If you’re switching from a darkish shade (similar to black) to a light-weight shade (like white or pure) it’s possible 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 shade 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’ll be able to trust that there will not be darkish materials combined with lighter materials.
Be aware: We beneficial eradicating the filament when comfortable slightly 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 wash out. Mushy removing additionally helps be sure that you get all the pieces out of the extruder tip.
What to do if issues go incorrect
There are just a few key issues to examine 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.”
- Make certain the extruder is on the proper top. Alter the restrict change or extruder to 0 top
- Make certain the print mattress is stage. Stage the mattress.
- Be sure to’re printing on the proper temperature and that your mattress is the suitable temperature.
- Test the ambient temperature of your atmosphere. If it’s too chilly or too sizzling exterior, your print can differ drastically!
“The half has dangerous inside layers and high surfaces.”
- Test the extrusion temperature (it’s possible you’ll want to extend it by 5 diploma bumps).
- Test the filament rigidity.
- Clear the filament drive gear.
- Lower your pace.
- Make certain your half is correctly cooled.
“The skin edges of my elements have a number of little bumps on them.”
- Make certain your printer is getting sufficient information. If printing from a pc, be sure that the pc shouldn’t be 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’ll be able to 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 suitable settings and persistence hobbyists have succeeded in printing all kinds of supplies a lot of which have very low viscosity. You need to be capable of 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 high layers that span gaps).
My half is curling out of bed.”
- Just remember to have a great 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.”
- Make certain your sizzling finish is getting sizzling. Test to ensure the recent finish is heating in any respect. If it isn’t, that you must have your printer serviced. It’s seemingly 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 be sure that now we have correct rigidity towards the filament. Often improper rigidity or a clogged drive gear will make the print look extra like the image now we have for low temperature filament, but it surely 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 may stop extrusion and is extra widespread with direct drives [the motor is directly connected to the drive gear] however much less widespread 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 sizzling finish. That is probably the most excessive kind 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 often on the junction between the extruder and sizzling finish. Take off the extruder and take away all of the ABS you’ll be able to (it’s possible you’ll want the recent finish sizzling to get all the fabric out.) If you cannot get out all of the filament by pulling, it’s possible you’ll must attempt to drive it down by the recent finish. We often use a small allen wrench. If this fails you’ll be able to attempt to drill out the extruder or sizzling finish however it’s possible you’ll want to switch elements. Be sure you take precautions towards being shocked or burned. If you’re not certified to do that work, discover somebody who’s, slightly than danger damage.
