ABS filament is a flexible materials that is an incredible possibility for once 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 obtainable in 3D printing in the present day. There are just a few further issues to contemplate when printing with ABS as in comparison with PLA, however the further hurdles are nicely 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 varieties of 3D printing filament on account of its versatility and power, and is commonly used for injection molding and merchandise like Lego, devices, sports activities tools and extra.
Nice tasks for ABS:

Getting that first layer proper
As with all 3D printing, getting the primary layer down is crucial a part of the print. Every thing 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 if you happen to’re struggling to get good mattress leveling, everybody has to study it. When 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.
- 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 total first layer is equally too excessive or too low throughout your complete print, modify 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 suitable temperature.

Greatest Mattress Setup for ABS
As a way to print with ABS, you want a headed mattress. The really useful mattress temperature for ABS is 110°C. Most fashionable 3D printers can attain this temperature, but when yours can not, you must be capable to get away with 90°C.
Word: 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 most effective construct floor for ABS is PEI, obtainable both easy or with a powder coated floor for further mechanical adhesion. You can even 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 won’t have to regulate this setting. Professional Tip: Your print mattress will probably 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 Greatest 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 doable, and as uniformly as doable. Right here are some things to remember to realize these objectives:
- Little to no layer cooling – begin along with your half cooling fan fully off.
- Enclosed construct space – preserve a steady and excessive ambient temperature round your half after it has been printed.
There are lots of totally enclosed 3D printers obtainable in the present day, along with enclosures obtainable as equipment for a lot of machines that don’t come totally enclosed. Moreover, take a look at our video under on constructing a customized, low-cost enclosure for any printer that may allow you to begin printing with ABS immediately.
In case your first layer will not be sticking:
- Be certain that the mattress is degree.
- Be certain that the mattress is scorching sufficient – we advocate 110°C.
- Guarantee that the ambient temperature of the print atmosphere isn’t too scorching or chilly (or else modify 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 your complete 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 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 begin 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 will have 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 components of your print and chances are you’ll discover that the extruder leaks out quite a lot of plastic whereas transferring between separate areas of the print. If this occurs you must attempt to incrementally decrease the temperature by 5 levels till the extruder will not be leaking a lot materials.
ABS being printed too scorching can produce a tough texture, in case your components really feel and/or look tough, attempt decreasing the temperature and see if that impact is lowered.
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 overview your retraction settings and probably tune this particularly.
If the temperature is simply too chilly:
You’ll both see that the filament will not be sticking to the earlier layer and you’re getting a tough floor, or you’re going to get an element that isn’t sturdy and will be pulled aside simply. In both case, you must enhance 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 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 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 chances are you’ll have to reverse the extruder.
- In case you are having bother eradicating the filament, enhance 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 coloration by the extruder till it runs clear and the brand new coloration is all that’s popping out of the extruder. In case you are switching from a darkish coloration (reminiscent of black) to a lightweight coloration (like white or pure) chances are you’ll need 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’ll be able to have faith that there will not be darkish materials combined with lighter materials.
Word: We really useful eradicating the filament when mushy somewhat 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 onerous to wash out. Delicate removing additionally helps make sure that you get every part out of the extruder tip.
What to do if issues go flawed
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 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. Modify the restrict change or extruder to 0 peak
- Be certain that the print mattress is degree. Degree the mattress.
- Be sure to’re printing on the proper temperature and that your mattress is the suitable temperature.
- Examine the ambient temperature of your atmosphere. If it’s too chilly or too scorching outdoors, your print can fluctuate drastically!
“The half has dangerous inner layers and prime surfaces.”
- Examine the extrusion temperature (chances are you’ll 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 a lot of little bumps on them.”
- Be certain that your printer is getting sufficient knowledge. If printing from a pc, make sure that the pc will not be 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’ll be able to attempt to print from the SD card. This usually helps the printer have sufficient knowledge to run extra easily.
Nonetheless, do not be too fast to imagine the issue is in your ABS. With the suitable settings and endurance hobbyists have succeeded in printing all types of supplies a lot of which have very low viscosity. It is best to 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 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 might help dramatically with tall sections of your print or when “bridging” (printing prime layers that span gaps).
My half is curling up and about.”
- 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 won’t extrude any materials.”
- Be certain that your scorching finish is getting scorching. Examine to verify the recent finish is heating in any respect. If it’s not, it’s worthwhile to 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 modify pressure. The very first thing we’re going to do is clear the filament touching drive gear and make sure 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, nevertheless it typically does forestall extrusion all collectively. Clear the pinch wheel with a wire brush, and ensure your pressure is nice and strong (an excessive amount of may also 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 drag out any particles which are within the extruder tip.
- Examine 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’ll be able to (chances are you’ll want the recent finish scorching to get all the fabric out.) If you cannot get out all of the filament by pulling, chances are you’ll have to 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 scorching finish however chances are you’ll want to exchange components. Remember to take precautions in opposition to being shocked or burned. In case you are not certified to do that work, discover somebody who’s, somewhat than threat damage.
