Affordable PLA 3D Printer Filament for Every Maker
PLA, aka Polylactic Acid, is a multipurpose material commonly used in 3D printing. PLA filament is a bioplastic, which means it is made from renewable natural resources such as corn starch and tapioca products. As a biodegradable material, it is much better for the environment, especially compared to petrochemical-based alternatives.
Recommended Extrusion Temperatures: 205±15°C
Recommended Bed Temperature: Not needed, but if printer has heated bed, 40±15 °C
1 kg spool
True Diameter: 1.75mm
Dimensional Accuracy: ±0.05mm
Density: 1.25 g/cm³
Volume: 0.80 L
Length: 332.60 m
If you are just begining 3d printing, Getting the First Layer Right .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.
----You need the print bed (or print surface) to be level.
----You need the extruder to be homed to the correct height from the bed.
----You need a good base material for your PLA to adhere to.
Printing on Blue Tape
Blue Tape, or Painters Tape, is one of the easiest and fastest ways to get a great print from PLA. Here is a quick checklist of things you want to make sure you are doing.
Are you use Blue tape on platform ?if not ,ignor below ,
Check that the Blue Tape creates an even layer. Don't miss any spots. Don't overlap the edges.
Don't heat the bed when using Blue Tape, it will not stick well to your PLA
Replace any tape strips that get damage when removing parts.
Replace the tape after 5-10 prints or when parts stop sticking.
If your first layer is not sticking - make sure the print head is close enough to make a nice squished line of PLA. If that doesn't take care of your problem, you may want to increase the 'first layer temperature' 5 to 10 degrees (start with 5 and increase if necessary).
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. To reduce the Blue Tape from pulling up, we have had great results putting Blue Tape on top of PET tape, but that's just crazy :).
NOTE: PLA will not stick well to Blue Tape when it is warm. 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. You should replace the tape when you start to see the adhesion degrading (usually somewhere between 5-10 prints on the same spot).
Printing On Glass With A Heated Bed
When you have a temperature controlled bed, printing directly on glass can be a great option. The recommended bed temperature for PLA is 70C.
Most common use Glass on platform ,read below ,
Having your bed level and extruder at the right height is extremely important when printing on glass. If your extruder is too far from the glass your PLA will not stick AT ALL, if it is too low the glass will completely block the extrusion of material and it will not stick AT ALL.
If your first layer is not sticking
Make sure the bed is level.
Make sure the nozzle is close enough to make a nice squished first layer.
Make sure you run the extruder enough before your print starts so there is filament going onto the bed during the entire first layer. In MatterControl you can turn the number of 'Skirt' loops up to 4 or 5 or more depending on the part.
Make sure the extruder temperature is hot enough to properly melt the filament. Otherwise, the plastic may cool too quickly and lift from the bed. This can cause the nozzle to snag on the first layer when traveling around the bed and gum it up. Many people like to set their first layer's extrusion temperature 5-10 degrees higher than the other layers to ensure a proper stick.
Make sure the speed for your print moves aren't too fast. Printing too fast can cause the plastic to cool too quickly and lift from the bed and cause a failed print.
Clean the glass with denatured alcohol
When you can get it working well, glass is the absolute best way to print PLA. It make a great shiny bottom layer and the heated bed ensures that parts stay nice and flat.
If the temperature is too high
You will see more strings between the separate parts of your print and you may notice that the extruder leaks out a lot of plastic while moving between separate areas of the print. If this happens you should try to incrementally lower the temperature by 5 degrees until the extruder is not leaking so much material.
Sometimes you will have a material that is simply less viscous than other PLA and will leak more even at lower temperatures. We recommend you increase the retraction a few millimeters (3-4 seems like a good number for most every PLA we have tried).
If the temperature is too cold
You will either see that the filament is not sticking to the previous layer and you are getting a rough surface (like the picture below), or you will get a part that is not strong and can be pulled apart easily. In either case, you should increase the temperature by 5 degrees and try again until you get good line segments on every layer and have a strong part when done printing.
