What’s ABS filament? ABS is among the mostly used and versatile supplies obtainable in 3D printing right this moment. There are just a few further issues to think about when printing with ABS as in comparison with PLA, however the further 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 among the hottest sorts of 3D printing filament attributable to 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:
- Automobile inside elements – cellphone mounts, cup holders
- Cosplay – sand completely easy and acetone-weld giant elements collectively
- Robots – robust sufficient to deal with weight and movement
- 3D Printers – Take a look at the Voron, made doable with ABS elements.
Our Advisable ABS Filaments:

- Worth: $68 per kg
- Options: PC is a superb materials, however tougher to print with than ABS so this compound gives the perfect of each worlds. It is also Flame Retardant, making this materials an ideal alternative for initiatives that must explicitly resist injury from fireplace.
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 expertise. Do not feel unhealthy in case you’re struggling to get good mattress leveling, everybody has to study it. Should you need assistance particularly on mattress leveling, try our article. Listed here are the important thing factors:
- You want the print mattress to be degree.
- Should 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)
- Should you whole first layer is equally too excessive or too low throughout your entire 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 proper 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 trendy 3D printers can attain this temperature, but when yours can not, it is best to be capable 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, obtainable both easy or with a powder coated floor for further mechanical adhesion. It’s also possible to 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 seemingly is not going to have to regulate this setting. Professional Tip: Your print mattress can 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 perfect outcomes.
Enclose Your Printer for the Finest 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 doable, and as uniformly as doable. Right here are some things to remember 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 lots of totally enclosed 3D printers obtainable right this moment, along with enclosures obtainable as equipment for a lot of machines that don’t come totally 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 shouldn’t be sticking:
- Be sure the mattress is degree.
- Be sure the mattress is scorching sufficient – we advocate 110°C.
- Ensure that the ambient temperature of the print surroundings isn’t too scorching or chilly (or else alter accordingly).
- Be sure you put the adhesive on the mattress.
- Be sure the print head is shut sufficient to make a pleasant first layer.
- Be sure you run the extruder sufficient earlier than your print begins so there’s filament going onto the mattress throughout your entire 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 totally primed.
-
PEI is a good way to print ABS. It makes an ideal 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 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 will have when creating 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 improvement.
What to search for
If the temperature is just too excessive:
You will notice extra strings between the separate elements of your print and it’s possible you’ll discover that the extruder leaks out numerous 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 shouldn’t be 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.
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 overview your retraction settings and probably tune this particularly.
If the temperature is just too chilly:
You’ll both see that the filament shouldn’t be sticking to the earlier layer and you might be getting a tough floor, or you’ll get a component that isn’t robust and will be pulled aside simply. In both case, it is 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 anticipate 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 it’s possible you’ll must 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.
- Enhance the warmth and cargo the brand new filament usually.
- Run the brand new shade via 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 certain 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 may trust that there will not be darkish materials blended with lighter materials.
Notice: We beneficial eradicating the filament when delicate fairly 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 exhausting to wash out. Comfortable removing additionally helps be certain that you get every little thing out of the extruder tip.
What to do if issues go fallacious
There are just a few key issues to test when your prints aren’t working. However earlier than we take a look at options we have to have a short description of your signs.
“I am unable to get the primary layer to stay.”
- Be sure the extruder is on the proper peak. Alter the restrict swap or extruder to 0 peak
- Be sure the print mattress is degree. Degree the mattress.
- Be sure you’re printing on the proper temperature and that your mattress is the proper temperature.
- Test the ambient temperature of your surroundings. 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 (it’s possible you’ll want to extend it by 5 diploma bumps).
- Test the filament pressure.
- Clear the filament drive gear.
- Lower your velocity.
- Be sure your half is correctly cooled.
“The skin edges of my elements have plenty of little bumps on them.”
- Be sure your printer is getting sufficient information. If printing from a pc, be certain that the pc shouldn’t be 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 information to run extra easily.
Nevertheless, do not be too fast to imagine the issue is in your ABS. With the proper settings and endurance hobbyists have succeeded in printing all types of supplies a lot of which have very low viscosity. You need to be capable 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 may 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 remember to 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 is not going to extrude any materials.”
- Be sure your scorching finish is getting scorching. Test to ensure the recent finish is heating in any respect. If it isn’t, you should have your printer serviced. It’s seemingly that you’ve got 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 certain that we have now correct pressure in opposition to the filament. Often improper pressure or a clogged drive gear will make the print look extra like the image we have now for low temperature filament, however it generally does stop extrusion all collectively. Clear the pinch wheel with a wire brush, and ensure your pressure is nice 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 got a small particle in your extruder tip jamming the plastic. Use the change filament approach described above to drag out any particles which are within the extruder tip.
- Test for and take away jams between the extruder and scorching finish. That is probably the most excessive sort of drawback 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 scorching finish. Take off the extruder and take away all of the ABS you may (it’s possible you’ll want the recent finish scorching to get all the fabric out.) If you cannot get out all of the filament by pulling, it’s possible 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 it’s possible you’ll want to switch elements. Make sure to take precautions in opposition to being shocked or burned. If you’re not certified to do that work, discover somebody who’s, fairly than threat harm.
