Your First 3D print: PLA polylactic acid

Your first 3D print, customize and model for your interest and want to keep it forever. However, this plastic is different from thermoplastic. You have read the recycling materials name PETE, HDPE, PVC, and others. But for 3D plastic or as they called filaments. these plastic are slightly new, but there is known plastic. To introduce the plastic is PLA, ABS, PETG, Flex, and others. the known materials is PVC, and maybe HDPE. But the main focus with the popular plastic is PLA or by polylactic acid.


PLA is a malleable material and easy to work with because of it's structure and properties. The material is easy to use and for prototypes and modeling. The plastic melting point is very low to melt through a heated brass nozzle. When the filament is inserted and enter the nozzle. it will began to heat itself and becomes malleable. And fluid filament will ooze out and continue to make a structure component. but will be guided by autonomous motors and mainboard or in simple words. It is controlled by the small computer and the small computer control the motors and the heated nozzle to make the component.


Now we talked about the material. but it has downside of it's properties. It is great because it is popular and used more frequent. But when it is bought and given to buyers. There's responsibility to take care of the material and it can still be recycled. Here is a list of downside of the material.

  • It will lose it's structure when set near a heated source for long-period of time. If you have it directly near the sun, a heater, or a lamp that has a heated light bulb. The plastic will lose it's structure and become malleable. The reason it is a low temperature material. So it can be printed with high heat, it will do the same with outside heated environment. So big suggestion is keep it in a cool area and normal temperature up to 90 F or 32.22 C.

  • It is fragile with models but stronger in part. When they are printed as a prototype to make part. It will hold it structure and it is very strong depend in the infill and solid wall. But with 3D printed model, props, or maybe collectables. they are brittle with curtain places. example, a horse is easy to print, but there is weak structure along the legs and tail. A model knight or warrior is easy to print, but weak structures along the arms, horns, sword, and sometimes the legs has weak structure. Props depends if they are fine detail and fine points will break easily.

  • Material is 100% recyclable because of it's low melting point. So if you want to recycle the broken part or throw it away. You can recycle it, comment or give us an email for more details on how to recycle the material.

  • PLA is not a fully cured plastic. the plastic is only a prototype and modeling area. It cannot be used for outside area for a permanent fix. To get the strong material. check out the Material & Machine selection and which one will be used for your component.

  • Not a toy, for curtain area. Some prints will be printed for toys if they are solid and specs. But for models and ornaments are not toys depend on the structure and sturdy.

  • It is not used for food product. FAA does not release any evidence if they are safe for food product. But for the business common sense that with 3D printing. they do leave stringiness and they are easy to clean up and re-heat to eliminate them. We do not consider to make them as a food product. Unless they are prototype for the look and approach with another method.

There is a list of pro and cons of these issues, but these are the main cons that if you are getting a 3D print item. Also consider more thoughts on the chat to begin conversation and we'll get back to you for the answers. Hope you enjoy the prints and remember they are functional and they will be make differently in a different approach if you want to consider another options. look at the material and we will stay connected have a good day.
