ABS filament is a flexible materials that is an amazing possibility for if you want your 3D-printed elements 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 accessible in 3D printing as we speak. There are just a few additional issues to think about when printing with ABS as in comparison with PLA, however the additional hurdles are properly value 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 varieties of 3D printing filament because of 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:

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 dangerous if you happen to’re struggling to get good mattress leveling, everybody has to study it. If you happen to need assistance particularly on mattress leveling, try our article. Listed here are the important thing factors:
- You want the print mattress to be degree.
- If you happen to 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)
- If you happen to complete first layer is equally too excessive or too low throughout the whole print, modify 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 best temperature.

Greatest Mattress Setup for ABS
So as 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’t, you need to have the ability to get away with 90°C.
Notice: 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, accessible both clean or with a powder coated floor for additional mechanical adhesion. You may also 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 doubtless won’t 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 one of the best outcomes.
Enclose Your Printer for the Greatest Outcomes
The trick to have ABS elements keep on the mattress throughout a print and never break 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 attain these objectives:
- Little to no layer cooling – begin together with your half cooling fan utterly off.
- Enclosed construct space – keep a steady and excessive ambient temperature round your half after it has been printed.
There are numerous absolutely enclosed 3D printers accessible as we speak, along with enclosures accessible as equipment for a lot of machines that don’t come absolutely enclosed. Moreover, try our video under 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:
- Be certain that the mattress is degree.
- Be certain that the mattress is sizzling sufficient – we advocate 110°C.
- Guarantee that the ambient temperature of the print setting isn’t too sizzling or chilly (or else modify accordingly).
- Ensure you put the adhesive on the mattress.
- Be certain that the print head is shut sufficient to make a pleasant first layer.
- Ensure you run the extruder sufficient earlier than your print begins so there’s 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 an amazing 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 typically 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 energy 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 got 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 assist in your print setting growth.
What to search for
If the temperature is simply 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 shifting between separate areas of the print. If this occurs you need 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 elements really feel and/or look tough, attempt reducing the temperature and see if that impact is decreased.
Generally you’ll have a cloth that’s merely much less viscous than ABS and can leak extra even at decrease temperatures. We advocate you evaluation your retraction settings and presumably tune this particularly.
If the temperature is simply 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, 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 achieved 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.
- Whenever you attain 120°C take away the present filament from the extruder. You could possibly again it out by hand or it’s possible you’ll 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 (corresponding to black) to a light-weight coloration (like white or pure) it’s possible you’ll need 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 coloration 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 trust that there will not be darkish materials blended with lighter materials.
Notice: We really useful eradicating the filament when mushy reasonably 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 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 flawed
There are just a few key issues to test 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 can not get the primary layer to stay.”
- Be certain that the extruder is on the proper top. Regulate the restrict change or extruder to 0 top
- Be certain that the print mattress is degree. Degree the mattress.
- Ensure you’re printing on the proper temperature and that your mattress is the best temperature.
- Test the ambient temperature of your setting. If it’s too chilly or too sizzling outdoors, your print can fluctuate drastically!
“The half has dangerous 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 rigidity.
- Clear the filament drive gear.
- Lower your pace.
- Be certain that your half is correctly cooled.
“The surface edges of my elements have numerous little bumps on them.”
- Be certain that your printer is getting sufficient knowledge. If printing from a pc, be certain that the pc is just not too busy to feed the printer instructions. If the printer is pausing it’s often because of the 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 typically 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 best settings and endurance hobbyists have succeeded in printing all kinds of supplies lots of which have very low viscosity. You must have the ability 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 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 might help dramatically with tall sections of your print or when “bridging” (printing high layers that span gaps).
My half is curling up and doing.”
- Just be sure you have an excellent quantity of adhesive on the mattress and that you just’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 sizzling finish is getting sizzling. Test to ensure the new finish is heating in any respect. If it isn’t, it’s good to have your printer serviced. It’s doubtless that you’ve got a free 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 modify 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 in opposition to the filament. Normally 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 typically does forestall extrusion all collectively. Clear the pinch wheel with a wire brush, and ensure your rigidity is sweet and stable (an excessive amount of also can 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 got a small particle in your extruder tip jamming the plastic. Use the change filament approach described above to drag out any particles which might be within the extruder tip.
- Test for and take away jams between the extruder and sizzling finish. That is probably the most excessive kind 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 often 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 (it’s possible you’ll want the new finish sizzling to get all the fabric out.) If you cannot get out all of the filament by pulling, it’s possible you’ll have to try to drive it down by means of the new finish. We often use a small allen wrench. If this fails you’ll be able to try to drill out the extruder or sizzling finish however it’s possible you’ll want to interchange 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, reasonably than danger harm.
