Polylactic Acid PLA is different than mo st thermoplastic polymers in that it is derived from renewable resources like corn starch or sugar cane. Most plasticsby contrast, are derived from the distillation and polymerization of nonrenewable petroleum reserves. Plastics that are derived from biomass e. It can be produced from already existing manufacturing equipment those designed and originally used for petrochemical industry plastics. This makes it relatively cost efficient to produce.
Accordingly, PLA has the second largest production volume of any bioplastic the most common typically cited as thermoplastic starch. There are a vast array of applications for Polylactic Acid. Some of the most common uses include plastic films, bottles, and biodegradable medical devices e.
For more on medical device prototypes both biodegradable and permanent read here. PLA constricts under heat and is thereby suitable for use as a shrink wrap material. On the other hand, its low glass transition temperature makes many types of PLA for example, plastic cups unsuitable to hold hot liquid.
They each have slightly different characteristics but are similar in that they are p roduced from a renewable resource lactic acid: C 3 H 6 O 3 as opposed to traditional plastics which are derived from nonrenewable petroleum. PLA production is a popular idea as it represents the fulfillment of the dream of cost-efficient, non-petroleum plastic production.
The huge benefit of PLA as a bioplastic is its versatility and the fact that it naturally degrades when exposed to the environment. For example, a PLA bottle left in the ocean would typically degrade in six to 24 months. Compared to conventional plastics which in the same environment can take several hundred to a thousand years to degrade this is truly phenomenal.
Accordingly, there is a high potential for PLA to be very useful in short lifespan applications where biodegradability is highly beneficial e. Of note, despite its ability to degrade when exposed to the elements over a long time, PLA is extremely robust in any normal application e.
PLA filament for 3D printing is typically available in a myriad of colors. Polylactic Acid could be CNC machined but it is typically not available in sheet stock or rod form. It is, however, typically available as a thin film for thermoforming or in the form of plastic pellets for injection molding. The PLA is later burned out as it has a lower melting temperature than the surrounding material.Update your browser to view this website correctly. Update my browser now.

Our PLA is significantly stronger than other brands, very easy to print with heated bed not required and long lasting. If however you need something a little harder wearing, and your printer has a heated bed — you might want to go for the ABS.
What temperature should I print my rigid. This varies between materials, so please check the recommendations on the specific product page.
Generally, due to the pure nature and high grade of our raw materials your extruder setting wants to be a little lower than normal. Different printers print rigid. With PLA, no. All other materials including Flex PLA require a heated bed to avoid warping during those first few layers. Not often. If printing direct to glass, your best bet would be to use a good quality glue stick and a apply a thin even layer to your bed before printing.
My 3D printer manufacture recommends only using their filament — can I use rigid. Short answer: Absolutely! You will find rigid. Will your spools fit my printer? Most likely, as our 1KG spools are fairly normally sized.

It is a renewable and biodegradable resource.
It is non-toxic and has a pleasant smell when printing. PLA filament comes in a wide range of colors and because of its thermal characteristics, is particularly easy to get great prints with.
PLA or Polylactic acid is a thermoplastic polyester. It is commonly derived from renewable resources, such as corn starch, tapioca roots or sugarcane. One of the most attractive things about PLA plastic is that it naturally degrades when exposed to the environment.
For example, an item made of PLA plastic in the ocean has a degradation time on the order of six months to two years. Compare this to conventional plastics, which take from to 1, years to degrade. It is important to point out that although PLA will degrade in an exposed natural environment it is very robust when used in any normal application such as a printed toy or a critical piece of a printer. In that respect, you can think of it as being similar to iron.
If you were to expose it to continuous moisture or leave it outside, it would "rust" and become unusable in short order. But if you had it in your home you would expect it to last nearly indefinitely. PLA comes in a number of grades; scientific, medical, food safe, and then to the type of PLA used in consumer 3D printing.
PLA's natural melting temperature is around 80C but it is mixed with other plastics to make it suitable for 3D printing. PLA is less thermally contractive and much easier to print big parts with. The thing to consider is that being stiffer and harder also means that it is more brittle. If the part you're printing will be used where it might receive a lot of banging or sharp collisions, PLA may not be the best material. This is why you should use ABS filament or some other material near the extruder.
At MatterHackers we generally use PLA filament for all our printer parts except those that are directly around the extruder such as the x-carriage, mounting plate and extruder block which we print in ABS. The first layer is the most important part of any print. There are a few things you need to do to get the first layer to stick well. Below is a video from MatterHackers' 3D printing series that will help guide you in the right direction for getting a stellar first layer.
View additional videos from this series. Here is a quick checklist of things you want to make sure you are doing. Blue Tape is not perfect but it is very easy to use and generally gives great results. However, sometimes your parts can pull the tape up off the glass during printing, and you will see some warping when that happens.
You do not want to heat the bed if you plan to print on Blue Tape. Also, the surface of the Blue Tape will lose its ability to hold onto a part with use.Written by Ken Giang.
Both are thermoplastics, meaning they enter a soft and moldable state when heated and then return to a solid when cooled.
Via the FDM process, both are melted and then extruded through a nozzle to build up the layers that create a final part. This article will discuss the main differences between these two commonly used materials. To learn more about the FDM process itself, click here to read a full-article.

ABS :. ABS Acrylonitrile Butadiene Styrene is a common thermoplastic well known in the injection molding industry. It is used for applications such as LEGO, electronic housings and automotive bumper parts. PLA Polylactic Acid is a biodegradable under the correct conditions thermoplastic derived from renewable resources such as corn starch or sugarcane. It is one of the most popular bioplastics, used for many applications ranging from plastic cups to medical implants.
Generally the tolerances and accuracy of FDM printed components are largely dependent upon printer calibration and model complexity. For connecting or interlocking parts, a tolerance of 0.
Due to its lower printing temperature, PLA, when properly cooled, is less likely to warp making it easier to print with and can print sharper corners and features compared to ABS. With a higher flexural strength and better elongation before breaking, 3D printed ABS can be employed for end use applications whereas PLA remains popular for rapid prototyping when form is more critical than function. ABS typically prints in a matte finish while PLA is semi-transparent, often resulting in a glossier finish.
Acetone is often used in post processing to smooth ABS, also giving the part a glossy finish. ABS can be easily sanded and is often machined for example, drilled after printing. PLA can also be sanded and machined, however greater care is required. A guide to post-processing FDM parts can be found here. If the aesthetics of a part are critical, then printing using SLA or Material Jetting is recommended. PLA is stable in general atmospheric conditions and will biodegrade within 50 days in industrial composters and 48 months in water.
ABS is not biodegradable, however it is recyclable. PLA is regularly used for the production of food related items, however confirmation by the filament manufacturer that it is safe to do so is recommended. Knowledge base. ABS: What's the difference?

Level up your 3D printing design skills Get a free 3D printing design rules poster.Polylactic acid PLA is a bio-degradable polymer that can be produced from lactic acidwhich can be fermented from crops such as maize.
This makes it an ideal candidate for use in certain energy rich, cash poor areas of the world. It is one of the two most common filaments, along with ABSpurchased for use in 3D printers in many western countries. It does exhibit higher friction than ABS however which can make it difficult to extrude and more susceptible to extruder jams. For more details, see the Wikipedia entry on Polylactic acid. Polylactic acid is a cheap, biodegradable polymer, that is produced from lactic acidwhich can be obtained from the maceration of starch and sugars in biotanks.
Typically it is produced from Genetically Modified Corn, grown in the United States, then processed as noted. Much has been made of it's decay in a concentrated Sodium Hydroxide Ultrasound Bath complete with ultrasound. Search for vinlandyoutube video makergear. It is dimensionally stable, so there is no need for a heated bed.How to find the perfect temperature for your 3D prints!
It is relatively inexpensive, and is not hard to source in filament form. You can get slightly higher quality surface finish with ABS over PLA, but on the whole PLA works better in the machine, requiring lower temperatures and giving stronger, more hard-wearing products.
It does have a slightly higher coefficient of friction in the drive and transport than ABS, but this is more than compensated for by its lower viscosity when molten.
This means lower pressure in the melt chamber and hence a lower driving force. There are different formulations of PLA available. Always check the producers notes on your pack of PLA! Depending on which formulation your filament is made from, you should adjust your heat accordingly. There has been some evidence that pigment may affect extrusion width. If you are switching plastics a lot, it is a good idea to measure the extrusion before going through the toolpath process.
The post suggests that for PLA at a given nozzle, temperature, there are limits to the feed rate, with the more dramatic underextrusion as the feedrate approaches the limit.
PLA bonds very very firmly to Acrylic, and it is not recommended to print directly on an Acrylic build surface.
It does stick well and is removed easily from various forms of Tape. It can also be printed on Polyimide Kapton that is pre-heated, but will be hard to remove until both the part and the surface are cooled. Some tips for printing on Polycarbonate:. PLA can absorb moisture from the air.
When it is heated this moisture can turn to steam bubbles which with certain hot end extruder head designs can interfere with printing. The symptom is that when the extruder motor stops the PLA kept coming out. When the stepper starts again there is a significant delay. Occasionally the tip may blow a bubble with a tiny puff of what looked like steam. Small amounts of PLA filament Natureworks PLAD has been tried can have some moisture removed by putting it on a piece of aluminum foil in an oven heated to F for an hour.
The filament in the oven is floppy, but sticks to itself only slightly. Flexing the coils after cooling unsticks them from each other. Heating a whole spool this way has not been tried, and may result in the spool becoming unusable, so caution is advised. Similar issues for propane fired ovens. Interestingly, a weight change can be seen after baking.
One coil went from PLA is the go-to material for most users due to its ease-of-use, dimensional accuracy, and low cost. Heated Bed Not Required Rigid. Polylactic Acid, commonly known as PLA, is one of the most popular materials used in desktop 3D printing.
It is the default filament of choice for most extrusion-based 3D printers because it can be printed at a low temperature and does not require a heated bed. PLA is a great first material to use as you are learning about 3D printing because it is easy to print, very inexpensive, and creates parts that can be used for a wide variety of applications. It is also one of the most environmentally friendly filaments on the market today.
Derived from crops such as corn and sugarcane, PLA is renewable and most importantly biodegradable. As a bonus, this also allows the plastic to give off a sweet aroma during printing. Before 3D printing with PLA make sure your 3D Printer meets the hardware requirements listed below to ensure the best print quality.
These tips will help you reduce the chances of common 3D printing issues associated with PLA such as stringing, oozing, or under-extrusion.
One of the most common problems with PLA is oozing. Since the filament flows relatively easily when compared to the other materials, it has a tendency to continue flowing during travel movements at the end of a segment. This creates strings or hairs on your part, and dialing in your retraction settings is the best way to combat this behavior! Different brands of PLA and different printers may need slightly different retraction settings, so you may need to experiment to find the best value for your printer.
For example, you could setup two vertical pillars which are printed side-by-side to evaluate stringing when moving back-and-forth between each pillar.
For example, you could try a different retraction distance for each 20mm section of the print and then pick the value that works best in the end. Cooling is one of the most important aspects of printing with PLA. Having a dedicated part cooling fan makes a huge difference in the quality of the printed parts. The freshly extruded plastic needs to cool down below the glass transition temperature as quickly as possible.
This will prevent the plastic from stringing and producing other artifacts. Simplify3D also includes a useful option on the Cooling tab of your process settings that can automatically reduce the print speed for small parts, ensuring that the layers have sufficient time to cool.
This can greatly improve the print quality by allowing the layer to solidify before printing the next layer on top of it. This setting can be found on the Speeds tab of your process settings. This is a great tip for any filament, but is especially useful for PLA which often contains different combinations of additives depending on the manufacturer.
These different additives can lead to variations in printing temperature between degrees Celsius. If you are not printing at the right temperature this can lead to several print quality issues including oozing, stringing, and under-extrusion. PLA can also be combined with different fills like metal, wood, and fiber that give it different characteristics than a standard homogeneous PLA. These may require different settings or even different hardware.
Be sure to check with the manufacturer of your filament to verify the optimal temperature to use for your specific filament. If you have trouble with stringing, try reducing this temperature by degrees, which will help prevent the excess oozing. Start thinking of project ideas by reviewing our common applications, try out one of the provided sample projects, or find a new filament to try from our list of popular material brands. ABS is a low-cost material, great for printing tough and durable parts that can withstand high temperatures.
Wood filaments combine a PLA base material with cork, wood dust, or other derivatives, giving the models a real wooden look and feel. PVA is commonly known for its ability to be dissolved in water and is often used as a support material for complex prints. How does PLA stack up against other materials?
