PLA (Polylactic Acid) filaments are very easy to use and perfect for beginners to do experiments. But what makes it one of the best 3D printing filaments?
We have compiled everything you need to know about this amazing filament in this article. Better knowledge about filaments ignites your creativity to explore your potential.
PLA is an eco-friendly 3D printing filament extracted from organic sources. The raw material used here is corn starch sugarcane and such. The production process of this thermoplastic monomer is what sets it apart from other 3D printing filaments.
The manufacturers use biomass resources for producing PLA filaments. You can use the equipment used to manufacture petrochemical plastics to produce PLA filaments. In this aspect, the difference in raw products doesn&#;t matter. And this also doesn&#;t rise the manufacturing cost which is a big plus.
PLA is eco-friendly as it is biodegradable, needs 65% less energy compared to manufacturing regular plastics, and is conceivably solvent welded. Moreover, it doesn&#;t have toxins and produces 68% lesser greenhouse gases.
Fermented starch from plants like maize, sugarcane, or cassava is used to produce PLA filaments. The fermentation of the raw materials transforms them into lactic acid which then makes PLA. Producers commonly use two methods to make PLA filaments.
1. Polymerization
2. Condensation
In the polymerization method, you will need metal catalysts. And to make large PLA molecules, blend lactide with metal catalysts. The condensation method isn&#;t much different from polymerization. The by-products and the temperature are a bit different from the former process.
You can produce wide-ranging blends of PLA filaments too by mixing materials like copper, bamboo, pine, cedar, bronze, carbon fibre, and more.
Mixing wood with PLA filaments makes the 3D-printed furniture more realistic. If you want to give printed parts a glossy look combine metal with PLA. This will make the print strong too.
Creality Ender, FlashForge and Artillery are some of the 3D printers most compatible with PLA materials. There are a few things you need to keep in mind whilst printing with PLA filaments are these are:
To ensure the best printing outcome you need to be more concerned about the hot end and nozzle temperature rather than the bed temperature. When the temperature is high, your print&#;s interlayer bonding becomes great. High temperature means faster printing and better material flow.
But increasing the temperature too high can affect the print by deforming some of the print parts. Too much temperature melts the extruded layers excessively and this can lead to print sagging or oozing.
For the best result, the print temperature should range from 200&#;230°C while printing with PLA filaments. Besides the ideal temperature can vary depending on the nozzle size and printing speed too. So, do some experimental prints to find the best temperature for your 3D printer.
Good bed adhesion is really important when printing with PLA or any other filaments. Bed adhesion refers to the capacity of the printed plastic to stay attached to the build plate while the printing process is still going on. If the print plastic comes loose, it can get fizzy.
To improve your printer&#;s bed adhesion, you can do the following:
Some well-liked bed surface options to print with PLA filaments are:
It is a kind of masking tape. You use it to cover the print bed to improve adhesion. These tapes tend to be porous which is perfect for filaments like PLA. Best blue tapes designed for improving the adhesiveness of the print bed are heat resistant.
These tapes work like a base layer and fend the surface of a printing bed. You need to use juice, glue, hair spray, or similar products for adhesion. The best thing about these tapes is that they come in large rolls. Thus, one sheet is enough for the bed surface. But be very careful when spreading out Kapton tape on the bed. Air bubbles can get trapped under the tape and create crinkles.
PEI sheets are great for printing with diverse printing filaments. With this, you will not need adhesive sprays, clips, or glues or do surface preparation for printing.
A glass bed is another excellent bed surface alternative you can consider. Glass beds are strong, dense, and durable and the price is reasonable too. We recommend getting carborundum glass. A 3-4 mm thick carborundum glass can handle the heat from 150 to 400 degrees.
The printing speed should be above 50 mm/s in terms of printing with PLA filaments. You can make top-tier aesthetic models if the printing speed is near 100 mm/s. But high-speed printing can warp the PLA. That&#;s why you need to run tests using varied printing speeds. It will help you find the right printing speed for your printer and the filament. When printing with PLA filaments, it&#;s ideal to print slower for ensuring optimal results.
For printing complex models with details, you need to slow down the print speed. In case you are printing a simple model it is better to increase the speed. Boost the extrusion rate for faster printing. You can also use the printhead&#;s acceleration count to increase the speed.
When your printed model is ready the next important thing is to make it look shiny, glossy, and realistic. And the entire process of doing so is called post-processing. You can split the whole process into two categories one is cleaning and the other is finishing.
Pre-sanding, sanding, and smoothing are processes that fall in the cleaning category. And priming and painting fall into the second category.
In this process, you would need sandpaper, pliers, tweezers, and a toothbrush to smoothen the surface of the print.
As the name suggests, you would need sandpapers in this post-processing stage. Buy 120-grit sandpaper PLA filaments and stay away from using them on the corners or edges of the print model. Smoothing is done to repair the deformity of prints thus it can take a lot of time. The bigger the print is the more time it will take for sanding.
Smoothing is really important to give your prints a shiny finish and just sanding cannot do that. Smoothing gets rid of the layer lines better than sanding can. Now, there are a lot of smoothing techniques you can use but here we are going to talk about chemical smoothing.
Chemicals such as ethyl acetate are a good option to smooth PLA filaments. This chemical will dissolve the layer lines without manual labour. Also, using the chemical doesn&#;t harm the layers underneath.
In this process you will require two things, one is a spray print and the other is a painter&#;s tape. The tape will firmly hold the print in place when you are spraying the paint. Spray paints come in vibrant colours and go very well with plastic.
Post-processing is really important to upgrade the appearance of the print, durability, and functionality. So, you need to be careful with the process. Following are some of the post-processing considerations you should keep in mind for a better printing finish:
If the temperature is not appropriate PLA filaments will not stick causing a rough surface. This can also make a particular part weak. Troubleshoot this problem by raising the temperature by 5°C. Now, try printing till you see the layers are adhering properly.
Excess stringing or overhang droops mean the temperature is too high for printing. In terms of PLA filaments, the more heat you use the shinier the prints become. To avoid overhangs, get the best layer cooling system. Regulating the settings of the printer&#;s retraction can help with the stringing. Lessen the temperature by 5°C if both methods fail.
It can happen if the bed surface is not levelled or the height of the nozzle is not right. So, check these sections. If the distance between the bed and the nozzle is not right PLA filaments can get dragged around.
This type of problem occurs when your printer doesn&#;t receive adequate data, your PLA filament is bad or the retraction settings lack tunning. Use your SDS card to troubleshoot this problem. Ensure to buy the best quality PLA filaments and check if the retraction settings are right.

PLA needs to be soaked in water hence the extrusion problem. Drying the filaments will fix this problem. Use a filament dryer or oven to bake. Lowering the printing speed also helps. To avoid fusing, keep the temperature lower than 50°C.
Filament stringing happens when the extruder gets too heated or the retraction settings are wrong. Thus, check if the settings are right and lower the temperature if the problem is with the extruder.
Permit the coasting function so it can turn off the extruder for a bit. During this time the filament can cool down a little for a better print. Also, tune the retraction settings for avoiding Zits & Blobs.
Enhancing the temperature of the bed, and using adhesives and enclosure should prevent warping. Adjusting the setting of the first layer and applying anti-warping tabs can also help.
PLA filaments are very popular, making them the second most manufactured bioplastic. It is relatively cheap and easier to handle. With the right printing settings, PLA filaments can create quality prints.

Consider the following variables while selecting PLA for manufacture. They also discussed how each factor influences his PLA choice. Let&#;s study:
The physical properties of plastics play an important role in the selection of plastics to manufacture. The stiffness, strength, flexibility, and heat resistance of plastics must be tailored to the application of the product.
Chemical Properties
The chemistry of the plastic material is also an important factor to consider. A PLA&#;s resistance to chemicals, UV light, and water is significant for the product&#;s longevity.
Manufacturing Process
The polylactic acid manufacturing process used to create the product should also be considered when choosing plastics. The process must mold the plastic into the desired shape and size without causing defects or material degradation.
The cost of plastic materials must be considered to make the final product cost-effective. Some plastics, such as polyethylene, are relatively inexpensive and widely available, while others, such as polycarbonate, are expensive due to their unique polylactic acid properties and manufacturing processes.
The environmental compatibility of plastic materials is also an important factor to consider. Plastics should be recyclable or biodegradable to reduce their environmental impact. For example, products made from bioplastics such as polylactic acid (PLA) help reduce the environmental impact of plastic waste.
Depending on the industry and application, PLA materials must meet specific regulations and standards. Plastics must meet safety and quality standards for their intended use. For example, food packaging plastics must be approved for contact with food.
In summary, PLA selection plays an important role in the success of the manufacturing process. Your choice of PLA can affect your final product&#;s performance, quality, and cost-effectiveness. Strength, durability, aesthetics, and cost must be considered when choosing the suitable plastic for each application.
Additionally, it is important to consider the environmental impact of plastics and strive to use more environmentally friendly plastics and processes. By consciously choosing the right plastics, you can improve your product&#;s functionality, durability, and sustainability while reducing their environmental impact.
