All about ABS filament (plastics) – features, requirements.

ABS filament

 

All about ABS filament.

 

Please note same effects and needs are with any filament base 3dprinters that want to do successful 3d printing.

ABS is Acrylonitrile Butadiene Styrene

 

Good Feature of ABS filament:

Black Friday has begun! Start making things for fun and business! Contact us!

1. It is a low-cost filament

2. It prints well with less stringing and gives a smooth finish

3. It is wear-resistant and impact-resistant is also good.

4. It holds up under sunshine very well and is heat tolerant.

 

Bad Features of ABS filament

1. Heavy warping

2. Needs heated bed, heated chamber, and draft-free.

3. Produces a pungent odor while printing needs ventilation

4. ABS Parts tend to shrink leading to dimensional inaccuracy

 

Hardware requirements for ABS;

  1. Heated Bed to temperatures of 95-110 c
  2. Build Surface Kapton Tape or ABS Slurry
  3. Extruder Temperature: 220-250 c
  4. Cooling part cooling fan not required.

 

Bed adhesion:

My Best setup includes using Brims and Rafts:

Highly Favoring rafts and supports where needed.

ABS Slurry is made by dissolving small amounts ABS in Jar with acetone then it is brushed on the printer’s heated bed with a thin coating. One exception is AnyCubic Predators heated bed need no slurry or tape applied just keep it clean with acetone or rubbing alcohol. Its glass bed is micro-grooved whereas all filaments stick to it and most all release while cooling.

 

Print in a well-ventilated Area:

Printing with ABS is known to produce a strong odor with fumes that could potentially be harmful if inhaled in large quantities. Avoid confined spaces and place your printer in a well-ventilated area to avoid these issues. Noted over the years some of the odor has been removed from ABS filaments but is still highly recommended to print in a well-ventilated area.

Venting the room by keeping a window open near your printer helps.

A small fan point out the window helps more if you don’t have an adequate ventilation system installed. I use also a networked video camera and close the room off to the rest of my house.

 

With the window open and an air condition home, I have turned off the AC vent. And because the window opens to bring in some breezes that large ABS prints to cool in unwanted ways. I encapsulated my Micro Make 3d delta printer with flexible corrugated plastic sheets and made a tiny window to check on the printing. I printed several attachments to slide the sheets into on the printer. Noted latest versions of Cura software has a new option for making a draft shield around your ABS print job.

This bobber I designed is 140mm round ABS printed very well with supports and with incased 3d printer .04mm nozzles size. No fan cooling was used.

Master Yoda 3d model

Yoda printed very nicely with ABS toys were downloaded from

Thingiverse – Digital Designs for Physical Objects

 

These made great gifts for friends with children into Star War’s movies

I have stored over 2600 files backed up on my network drives from the beginning of my printing.

I have used all Cura software from the start.

This picture is showing infill and raft and supports aiding in the printing were needed.

As you might notice in the picture how infill supports the curved area of the object to be printed as well as supports aid in outside areas were needed. Note supports the space between the support and what is supported is adjustable in the Cura software.

3d design ABS infill

Please Note that in Cura and quite possibly any good version of 3d printing software there should be basic settings for ABS Filaments and some by brand name. Also on the spools, they come in you will find bed heat and filament temps you can use with the product.

Once you are put your object in software and configure it for your printer in Cura you can select the type filament and on the right upper you can dropdown box and select expert for adding in settings and fine-tuning for best results in 3d prints. Also if you change nozzle sizes there is a place for you to add into the program that information and it will adapt default settings for its use. Such as speed setting the larger the nozzle the faster you can print but you will degrade the finish and quality of your printed objects. Most standard 3d nozzles are of .04 mm and it give really great results. I have switched to a .05mm nozzle because I was printing with fiber and wood inside of filaments. This small increase of nozzle size still giving great accurate prints with a bit smoother finishes.

 

Finish enhancement with ABS by using Acetone Fumes for a short period of time. This will cause the ABS skin to flow and smooth out in a very short time. You need a container big enough to suspend your object in the air with a little acetone on the bottom it will evaporate and the fumes will cause the skin of the object to be liquefied and flow over the layer and smooth them out.

 

This happens rather fast so don’t forget your item or you will ending up with ABS paint for later uses.

 

Happy 3d Printing it’s a fun exciting hobby to have.

 

 

My Name is Bruce Benson and sharing in this article my ABS experience with two Delta style 3d printers. I have been 3d printing for over six years now and design and print using ABS were needed is wonderful.
