ABS filament is a flexible materials that is an excellent possibility for while you want your 3D-printed components to be sturdy 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 out there in 3D printing at this time. There are a number of further issues to contemplate when printing with ABS as in comparison with PLA, however the further hurdles are properly price 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 varieties of 3D printing filament attributable to its versatility and power, and is usually used for injection molding and merchandise like Lego, devices, sports activities gear and extra.

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 abilities. Do not feel unhealthy if you happen to’re struggling to get excellent mattress leveling, everybody has to study it. In the event you need assistance particularly on mattress leveling, try our article. Listed here 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 top from the mattress. (Z-offset)
- In the event you whole 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 best temperature.

Greatest Mattress Setup for ABS
With a view 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 not, it’s best to have the ability to get away with 90°C.
Word: 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, out there both clean or with a powder coated floor for further mechanical adhesion. You may as well print on glass with adhesion promoters like Magigoo or a normal 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 possible is not going to have to regulate this setting. Professional Tip: Your print mattress will probably be a barely completely different form when absolutely heated to ABS print temperatures, so at all times 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 attainable, and as uniformly as attainable. Right here are some things to bear in mind to realize these objectives:
- Little to no layer cooling – begin along 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 a lot of absolutely enclosed 3D printers out there at this time, along with enclosures out there as equipment for a lot of machines that don’t come absolutely 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 instantly.
In case your first layer is just not 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 complete 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 absolutely primed.

PEI is an effective way to print ABS. It makes an excellent 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 gotten when growing your print settings.
FYI – there’s a temperature tower function 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 just too excessive:
You will notice extra strings between the separate components of your print and you could discover that the extruder leaks out numerous plastic whereas transferring between separate areas of the print. If this occurs it’s best to attempt to incrementally decrease the temperature by 5 levels till the extruder is just not leaking a lot materials.
ABS being printed too sizzling can produce a tough texture, in case your components really feel and/or look tough, strive reducing the temperature and see if that impact is diminished.
Generally you should have a fabric 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 just too chilly:
You’ll both see that the filament is just not sticking to the earlier layer and you might be getting a tough floor, or you’re going to get a component that isn’t sturdy and will be pulled aside simply. In both case, it’s best to improve 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 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 ahead 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 you could have to reverse the extruder.
- If you’re having bother eradicating the filament, improve 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 colour by way of 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 (akin to black) to a light-weight colour (like white or pure) you could need to extrude for a couple of minutes to be you positive have no 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’ll be able to have faith that there will not be darkish materials combined with lighter materials.
Word: We really helpful eradicating the filament when comfortable fairly 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 might trigger jamming and are onerous to scrub out. Delicate elimination additionally helps make sure that you get every little thing out of the extruder tip.
What to do if issues go incorrect
There are a number of 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 swap or extruder to 0 top
- Make certain the print mattress is stage. Degree the mattress.
- Be sure to’re printing on the proper temperature and that your mattress is the best temperature.
- Test the ambient temperature of your atmosphere. If it’s too chilly or too sizzling exterior, your print can range drastically!
“The half has unhealthy inner layers and high surfaces.”
- Test the extrusion temperature (you could want to extend it by 5 diploma bumps).
- Test the filament rigidity.
- Clear the filament drive gear.
- Lower your velocity.
- Make certain your half is correctly cooled.
“The surface edges of my components have a number of little bumps on them.”
- Make certain your printer is getting sufficient information. If printing from a pc, make sure that the pc is just not too busy to feed the printer instructions. If the printer is pausing it’s normally 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.
Nevertheless, 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 types of supplies a lot of which have very low viscosity. You must 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 it’s best to allow “Cooling” within the print settings.
- Get a small fan. In case your printer doesn’t have an built-in fan it’s best to 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 away from bed.”
- Just be sure you have quantity of adhesive on the mattress and that you simply’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 is not going to extrude any materials.”
- Make certain your sizzling finish is getting sizzling. Test to ensure the recent finish is heating in any respect. If it’s not, it’s good to have your printer serviced. It’s possible that you’ve 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 alter rigidity. The very first thing we’re going to do is clear the filament touching drive gear and make sure that we now have correct rigidity towards the filament. Normally improper rigidity or a clogged drive gear will make the print look extra like the image we now have for low temperature filament, but it surely generally does forestall extrusion all collectively. Clear the pinch wheel with a wire brush, and ensure your rigidity is nice and strong (an excessive amount of also can forestall 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 are within the extruder tip.
- Test for and take away jams between the extruder and sizzling finish. That is probably the most excessive sort of downside as a result of now it is time to take issues aside. Generally 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’ll be able to (you could want the recent finish sizzling to get all the fabric out.) If you cannot get out all of the filament by pulling, you could have to attempt to drive it down by way of the recent finish. We normally use a small allen wrench. If this fails you’ll be able to attempt to drill out the extruder or sizzling finish however you could want to interchange components. You should definitely take precautions towards being shocked or burned. If you’re not certified to do that work, discover somebody who’s, fairly than danger damage.
