ABS filament is a flexible materials that is a terrific possibility for whenever you want your 3D-printed elements 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 without doubt one of the mostly used and versatile supplies accessible in 3D printing right now. There are just a few additional issues to contemplate when printing with ABS as in comparison with PLA, however the additional hurdles are properly price 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 without doubt one of the hottest forms of 3D printing filament resulting from its versatility and power, and is commonly 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 an important a part of the print. Every little 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. Should you need assistance particularly on mattress leveling, try our article. Listed below are the important thing factors:
- You want the print mattress to be stage.
- 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 right peak from the mattress. (Z-offset)
- Should you whole first layer is equally too excessive or too low throughout your complete print, regulate your Z-Offset.
- You want a great 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
In an effort to print with ABS, you want a headed mattress. The advisable mattress temperature for ABS is 110°C. Most fashionable 3D printers can attain this temperature, but when yours can’t, you must 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, accessible both clean or with a powder coated floor for additional mechanical adhesion. You may as well 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 if you’re 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 absolutely 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 Greatest 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 bear in mind 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 absolutely enclosed 3D printers accessible right now, 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:
- Ensure the mattress is stage.
- Ensure the mattress is sizzling sufficient – we advocate 110°C.
- Make it possible for the ambient temperature of the print setting isn’t too sizzling or chilly (or else regulate accordingly).
- Ensure you put the adhesive on the mattress.
- Ensure 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 may be filament going onto the mattress throughout your complete first layer. In MatterControl you possibly can 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 terrific 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 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 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 characteristic construct into MatterControl so you possibly can create customized temperature towers to help in your print setting growth.
What to search for
If the temperature is just too excessive:
You will notice extra strings between the separate elements of your print and chances are you’ll discover that the extruder leaks out loads of plastic whereas shifting between separate areas of the print. If this occurs you must 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 diminished.
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 assessment your retraction settings and probably 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 might be getting a tough floor, or you’re going to get a component that isn’t sturdy and could be pulled aside simply. In both case, you must enhance the temperature by 5 levels and check out once more till you get good line segments on each layer and have a robust half when executed 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.
- While you attain 120°C take away the present filament from the extruder. You could possibly again it out by hand or chances are you’ll must reverse the extruder.
- If you’re having hassle eradicating the filament, enhance the temperature to 180°C and check out 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 colour by means of the extruder till it runs clear and the brand new colour is all that’s popping out of the extruder. If you’re switching from a darkish colour (similar to black) to a light-weight colour (like white or pure) chances are 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 colour 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.
Be aware: We advisable eradicating the filament when smooth fairly than when absolutely 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 laborious to wash out. Mushy elimination additionally helps make sure that you get all the pieces 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.”
- Ensure the extruder is on the proper peak. Alter the restrict change or extruder to 0 peak
- Ensure the print mattress is stage. Stage 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 differ drastically!
“The half has dangerous inner layers and prime surfaces.”
- Test the extrusion temperature (chances are you’ll want to extend it by 5 diploma bumps).
- Test the filament stress.
- Clear the filament drive gear.
- Lower your velocity.
- Ensure your half is correctly cooled.
“The surface edges of my elements have a lot of little bumps on them.”
- Ensure your printer is getting sufficient knowledge. If printing from a pc, make 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 laptop being too busy.
- Print from the SD card. On some printers you possibly can attempt to print from the SD card. This usually helps the printer have sufficient knowledge to run extra easily.
Nevertheless, do not be too fast to imagine the issue is in your ABS. With the best settings and persistence hobbyists have succeeded in printing all types of supplies lots 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 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 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 a great quantity of adhesive on the mattress and that you simply’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.”
- Ensure your sizzling finish is getting sizzling. Test to ensure the recent finish is heating in any respect. If it’s not, you must have your printer serviced. It’s probably that you’ve got a free connection, or your electronics have been fried (assuming the printer continues to be linked and responding to your host software program).
- Clear the drive gear and regulate stress. The very first thing we’re going to do is clear the filament touching drive gear and make sure that we’ve got correct stress in opposition to the filament. Normally improper stress or a clogged drive gear will make the print look extra like the image we’ve got for low temperature filament, however it typically does stop extrusion all collectively. Clear the pinch wheel with a wire brush, and ensure your stress is nice and strong (an excessive amount of may also 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 method described above to drag out any particles which can be within the extruder tip.
- Test for and take away jams between the extruder and sizzling finish. That is essentially 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 normally on the junction between the extruder and sizzling finish. Take off the extruder and take away all of the ABS you possibly can (chances are you’ll want the recent finish sizzling to get all the fabric out.) If you cannot get out all of the filament by pulling, chances are you’ll must attempt to drive it down by means of the recent finish. We normally use a small allen wrench. If this fails you possibly can attempt to drill out the extruder or sizzling finish however chances are you’ll want to exchange elements. Make sure you 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.
