ABS filament is a flexible materials that is a fantastic choice for while you want your 3D-printed components 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 immediately. There are a number of additional issues to contemplate when printing with ABS as in comparison with PLA, however the additional hurdles are nicely 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 sorts of 3D printing filament on account of its versatility and energy, and is usually 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. The whole lot 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 the event 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 degree.
- 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 proper peak from the mattress. (Z-offset)
- In case you whole first layer is equally too excessive or too low throughout the whole 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 appropriate temperature.

Finest Mattress Setup for ABS
With a purpose 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 not, it’s best to be capable to 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!
The perfect construct floor for ABS is PEI, out there both easy or with a powder coated floor for additional mechanical adhesion. You can even 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 possible won’t have to regulate this setting. Professional Tip: Your print mattress shall 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 Finest Outcomes
The trick to have ABS components keep on the mattress throughout a print and never cut 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 targets:
- Little to no layer cooling – begin together with your half cooling fan fully off.
- Enclosed construct space – keep a secure and excessive ambient temperature round your half after it has been printed.
There are numerous absolutely enclosed 3D printers out there immediately, along with enclosures out there 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 straight away.
In case your first layer is just not sticking:
- Be certain that the mattress is degree.
- Be certain that the mattress is sizzling sufficient – we suggest 110°C.
- Guarantee that the ambient temperature of the print setting isn’t too sizzling or chilly (or else alter 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 the whole first layer. In MatterControl you’ll be able to add a skirt and calibrate how a lot materials you want to extrude to make sure the hotend is absolutely primed.

PEI is a good way to print ABS. It makes a fantastic shiny backside layer and the heated mattress ensures that your components 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 energy of the half to be in good steadiness with one another. This temperature vary is a generalization, so please reference the precise filament you might have when growing 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 growth.
What to search for
If the temperature is just too excessive:
You will note extra strings between the separate components of your print and you might discover that the extruder leaks out quite a lot of plastic whereas shifting 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, attempt reducing the temperature and see if that impact is lowered.
Generally you should have a fabric that’s merely much less viscous than ABS and can leak extra even at decrease temperatures. We suggest you overview 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’re getting a tough floor, or you’ll get a component that isn’t sturdy and may 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 powerful half when performed 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 anticipate it to warmth up.
- Once you attain 120°C take away the present filament from the extruder. You could possibly again it out by hand or you might must reverse the extruder.
- If you’re having hassle 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.
- Enhance the warmth and cargo the brand new filament usually.
- Run the brand new shade by means of 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 (comparable to black) to a lightweight shade (like white or pure) you might wish 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 shade in it, or run the extruder for a number of minutes. It might take as a lot as 10 to fifteen minutes of extrusion earlier than you’ll be able to believe that there will not be darkish materials blended with lighter materials.
Be aware: We beneficial eradicating the filament when gentle somewhat 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 arduous to scrub out. Smooth elimination 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 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.”
- Be certain that the extruder is on the proper peak. Regulate the restrict change 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 appropriate temperature.
- Examine the ambient temperature of your setting. If it’s too chilly or too sizzling exterior, your print can range drastically!
“The half has unhealthy inner layers and prime surfaces.”
- Examine the extrusion temperature (you might want to extend it by 5 diploma bumps).
- Examine the filament pressure.
- Clear the filament drive gear.
- Lower your pace.
- Be certain that your half is correctly cooled.
“The surface 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 is just not 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’ll be able to try 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 appropriate settings and endurance hobbyists have succeeded in printing all types of supplies a lot of which have very low viscosity. You must be capable 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 might help dramatically with tall sections of your print or when “bridging” (printing prime 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 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. Examine to verify the new finish is heating in any respect. If it’s not, you must 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 related and responding to your host software program).
- Clear the drive gear and alter pressure. The very first thing we’re going to do is clear the filament touching drive gear and be sure that we’ve got correct pressure in opposition to the filament. Normally improper pressure 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 forestall extrusion all collectively. Clear the pinch wheel with a wire brush, and ensure your pressure is nice and stable (an excessive amount of may also forestall 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 might be that you’ve a small particle in your extruder tip jamming the plastic. Use the change filament approach described above to drag out any particles which can be within the extruder tip.
- Examine for and take away jams between the extruder and sizzling finish. That is essentially the most excessive kind 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 might want the new finish sizzling to get all the fabric out.) If you cannot get out all of the filament by pulling, you might must try to drive it down by means of the new finish. We normally use a small allen wrench. If this fails you’ll be able to try to drill out the extruder or sizzling finish however you might want to switch components. 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, somewhat than danger damage.
