We are amidst the fourth industrial revolution, and technology has taken the central role in the on-going chaos. The 3D printing technology is one such bright example and hence could not be ignored at all cost. ABS filament, the darling of the 3D printing technology, has transformed how the products are manufactured in an entirely inexpensive way.
However, the items are limited to a fraction of the exposure only. However, elements like ASA filament have proved to be effective in all climatic and external pressures and hence is loved by enthusiasts all across the globe.
So What Exactly Is ASA?
ASA is the acronym for the chemical compound Acrylonitrile Styrene Acrylate. The substance is used extensively in 3D printing and shares similarity in the molecular structure of ABS – another item used extensively in 3D printing. The material is resistant to weather conditions, and UV radiation compared to ABS and hence is quite popular all across the globe.
The strength of the substance makes it suitable for outdoor applications like garden fixtures (drain pipes, flower boxes, shutters, gutters, and others) to outdoor adventure equipment like boat hulls, shutters and flower boxes. In addition to it, the ASA filament is also wildly used in the automotive industry like bumper covers, grilles, side-view mirror housings, and others.
Understanding the Benefits of Using ASA
When it comes to the ASA filament, there are a ton of factors that come into play. The mechanical properties of the substance make it suitable for outdoor solutions. The filament retains its glossy finish, mechanical properties, and color even after prolonged exposure.
On the other hand, the item displays more significant resistance to environmental stress in comparison to its counterparts and hence is a huge hit all across the globe. To add on top of it, the thermoplastic products are heat and chemical degradation, making it one of the most sought after products among the 3D printing enthusiasts.
Printing Your First Item Out of the ASA Filament
The printing procedure is quite simple and requires quite a simple procedure to follow.
Step 1: Make Sure That Your First Layer Has Been Done Right
The first step in the process involves two significant distinct steps that ensure the first layer is even and without dirt and debris while maintaining the nozzle at an appropriate distance.
Leveling the Bed
The first thing in the process is to ensure that the bed is at the right level. Most printers come up with clear instructions about the same while on the other hand, some of the major companies provide a bed from their end. Using the screws attached, one can adjust the levels for better solutions.
Here are a few things to watch out.
- Move the print head out of the way of the bed to prevent it from crashing.
- Make the Z-axis as close to the device possible. The nearer is the nozzle to the Z-axis, the better it is. If there exists some gap between the printer and the nozzle, then it’s perfect. However, if the gap exceeds certain limitations, then an ideal thing is to tighten the screw and tilt it at an angle.
- Then move the print ahead of the three or four screws and insert a piece of paper between the bed and the nozzle.
- Loosen the screw until there is quite an amount of resistance between the bed and the nozzle.
- Repeat the procedure with the rest of the screws to make sure a certain level of accuracy is achieved.
Adjusting the Nozzle Distance
The next step in the process is changing the nozzle distance. Here are some of the tricks to follow.
- Make sure that your material for the bed is already applied by now.
- Test and trail the results with a skirt that uniformly covers the entire area of the bed.
- Observe how the filament has been laid out. Is it uniform and dense? Or is it bubbling up against each other? Try to get a thorough knowledge of a few trails and errors.
- If nothing works out, try rotating each screw by the same amount to get the most exquisite finish on the skirt. Otherwise, you can manually change the settings of the 3D printer to get the best results.
Step 2: The Printing Bed and the Adhesion
If by now the bed is not attained, the ASA filament may not work in favor of you. The ASA needs the right temperature and splits if the temperatures are not up to the mark. Here are some of the steps to get things right.
- Print with a brim. Fifteen loops of the rim are sufficient enough to print anything.
- Try to maintain a high range of temperatures, such as 110C. Most printers do not support that much and hence should be avoided at all costs.
- If the hairspray for the adhesion does not work out, use the molten ABS juice to brush the bed adhesive to get the best results.
- One can also opt for Kapton tape along with the hairspray to uniformly spread heat all across the printer.
Step 3: Calibrate the Print Temperature
As a rule of thumb, with the ASA filament, most experts print at 250 degrees Celsius and a bed temperature of 110 degrees Celsius.
- For better results, adjust the temperature by more or less five degrees at one time.
- Printing too hot for the filament is not an issue. Rather than writing at low temperatures can ruin the entire experience.
Step 4: Avoiding Wrapping and Splitting
Despite no matter what, all most all the 3D printed material wrap out from the edges and thus, spoils the entire project. The following is achieved with the quick cooling of one layer concerning another. Here are a few tips to get the best results.
- Build an enclosure for your model to sustain the heat and draft out the cold air.
- Turn off the cooling fans as it will prevent some parts from drying faster than the others.
Step 5: Changing the Filament
The last element in the process is changing the filament. While the procedure is relatively easy for the ASA filament, other methods can, too, follow the same to get the best results.
- Heat the filament to the highest temperature and pull out the previous filament smoothly.
- The nozzle is already filled with the previous elements and hence keep on heating until it is completely drained out.
- Once the previous filament is completely drained out, insert the other filament until the next color starts to drain.
Step 6: Regularly Maintain and Take Care of the Devices
Once you have learned the ins and outs of the industry, the next step is to regularly maintain and take care of. For example, if you aren’t able to remove ASA at all and the hot end is at temperature, then chances exist that the nozzle is stuck. Ask the experts for help, and you will get a ton of information from the house of MakeShaper.
The world of 3D printing is still in its nascent stage and is expected to boom all across the globe on account of serious developments in technology like the ASA filament. The industry is characterized by a number of factors based on which it is expected to flourish exponentially all across the globe.
