ABS filament is a flexible materials that is an incredible 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 right now. There are a number of further issues to think about when printing with ABS as in comparison with PLA, however the further hurdles are properly value 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 forms of 3D printing filament because of its versatility and power, and is commonly used for injection molding and merchandise like Lego, devices, sports activities gear and extra.
Nice tasks for ABS:

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 case you’re struggling to get good mattress leveling, everybody has to study it. When 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.
- When 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)
- When you whole first layer is equally too excessive or too low throughout your entire print, alter your Z-Offset.
- You want an excellent adhesive to help your ABS in sticking to the mattress.
- And naturally, ensuring that your extruder/hotend is heated to the precise temperature.

Finest Mattress Setup for ABS
As a way to print with ABS, you want a headed mattress. The advisable mattress temperature for ABS is 110°C. Most trendy 3D printers can attain this temperature, but when yours can not, you need to have the ability 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, out there both easy or with a powder coated floor for further mechanical adhesion. You can too 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 probably 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 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 potential, and as uniformly as potential. 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 steady and excessive ambient temperature round your half after it has been printed.
There are numerous totally enclosed 3D printers out there right now, along with enclosures out there 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 may allow you to begin printing with ABS instantly.
In case your first layer isn’t sticking:
- Be sure the mattress is stage.
- Be sure the mattress is scorching sufficient – we advocate 110°C.
- Make it possible for the ambient temperature of the print surroundings isn’t too scorching or chilly (or else alter accordingly).
- Be sure to put the adhesive on the mattress.
- Be sure 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 your entire first layer. In MatterControl you possibly can 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 an incredible 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 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 might have when creating your print settings.
FYI – there’s a temperature tower function construct into MatterControl so you possibly can create customized temperature towers to assist in your print setting growth.
What to search for
If the temperature is simply too excessive:
You will note 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 you need 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 components really feel and/or look tough, strive decreasing the temperature and see if that impact is decreased.
Typically you’ll 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 probably 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’re getting a tough floor, or you’re going to get a component that isn’t sturdy and might be pulled aside simply. In both case, you need 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 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.
- While you attain 120°C take away the present filament from the extruder. You could possibly 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.
- Enhance the warmth and cargo the brand new filament usually.
- Run the brand new coloration by means of 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 (akin to black) to a light-weight coloration (like white or pure) you could wish to extrude for a couple of minutes to be you certain have no 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 possibly can believe that there will not be darkish materials combined with lighter materials.
Notice: We advisable eradicating the filament when gentle relatively 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 might trigger jamming and are arduous to scrub out. Delicate removing additionally helps be certain that you get all the things out of the extruder tip.
What to do if issues go flawed
There are a number of key issues to verify when your prints aren’t working. However earlier than we have 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. Regulate the restrict change or extruder to 0 peak
- Be sure the print mattress is stage. Stage the mattress.
- Be sure to’re printing on the proper temperature and that your mattress is the precise temperature.
- Test the ambient temperature of your surroundings. If it’s too chilly or too scorching exterior, your print can fluctuate drastically!
“The half has unhealthy inside layers and prime 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 pace.
- Be sure your half is correctly cooled.
“The skin edges of my components have a number of little bumps on them.”
- Be sure your printer is getting sufficient information. If printing from a pc, be certain that the pc isn’t too busy to feed the printer instructions. If the printer is pausing it’s often because of the laptop being too busy.
- Print from the SD card. On some printers you possibly can attempt to print from the SD card. This typically 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 precise settings and persistence 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 you need to allow “Cooling” within the print settings.
- Get a small fan. In case your printer doesn’t have an built-in fan you need to look into getting a small desk fan. This may also help dramatically with tall sections of your print or when “bridging” (printing prime layers that span gaps).
My half is curling out of bed.”
- Just be sure you have an excellent 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 won’t extrude any materials.”
- Be sure your scorching finish is getting scorching. Test to verify the recent finish is heating in any respect. If it isn’t, it’s essential to have your printer serviced. It’s probably that you’ve a unfastened connection, or your electronics have been fried (assuming the printer remains 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 certain that we have now correct rigidity towards the filament. Often improper rigidity 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 rigidity is nice and strong (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 approach described above to drag out any particles which can 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 often on the junction between the extruder and scorching finish. Take off the extruder and take away all of the ABS you possibly can (you could want the recent finish scorching 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 means of the recent finish. We often use a small allen wrench. If this fails you possibly can attempt to drill out the extruder or scorching finish however you could want to switch components. Be sure you take precautions towards being shocked or burned. If you’re not certified to do that work, discover somebody who’s, relatively than threat harm.
