Sometimes, printing great results may seem more like an artform than a science. However, there are many methods to increase your chances of success printing high-quality prints. This guide will help you select the best filament.

You'll have to be able to control the printer, software and filaments, set-up, and last but not least your personal flair. You may already have one star wars 3d prints or one in mind. We'll begin by selecting a suitable 3D filament for your printer.

The reason why you shouldn't choose the filament with the lowest price

With the wide variety of filament available and the variety of vendors out there , it can be difficult to find that perfect one that suits you without wasting time and money trying to find it. I can't tell you what firm to choose however, don't get too cheap. You'll be paying for what you get and it's more times then not, cheap for a reason.

One of the aspects that you must be aware of when picking filaments is:

* Diameter uniformity

* Moisture

* A consistent viscosity and debris

Consistency of the Diameter of Filament

Lets start with 3d printed gifts filament diameter. 3mm vs 2.85mm against 1.75mm. Personally, I think 1.75mm is superior and here's the reason. It's more readily available and of better quality. It's usually more recent and is taken out of stock quicker which allows for more recent products to be manufactured and placed on shelves. It seems to have superior extruding, retraction, and generally better plastic flow. It makes sense as the motor that extrudes requires more rotations to extrude the same amount of plastic. The ratio is 3mm / 2.85mm leading to higher precision and better control of flow. Regardless of the size you choose the diameter must be uniform and uniform across. Spring tensioners are a common feature in printers. Therefore, minor variations in diameter like -/+.03mm should not be an issue.

Filament Moisture

Another problem is the presence of moisture. it is typically because of poor packaging or stored too long out of the package. Plastic will absorb water from the air relative to the humidity and duration of exposure. If you notice water vaporizing out of the hot-end, it is likely that the filament is moist. Ultimately this leads to poor prints and poor layer adhesion. You can know more about fusion 360 vs inventor, by visiting our website.

Moisture free filament

Certain 3d printer materials, such as PLA or Nylon can absorb moisture from the air. This absorption can cause problems such as affecting print quality, and causing damage to your hot-end through obstruction.

Hot-End Damage: Absorption of moisture results in filament swelling. If the swelling is large enough that the plastic expands, it will stop the nozzle from moving and could cause permanent hot-end damage.

Print Quality The plastic melts and the water that has been trapped becomes steam. This leads to bubbling. This bubbling causes an inefficient extrusion speed, which results in models which aren't durable and high quality. Not to mention that they look ugly.

Vacuum bags are a cheap solution to stop filament moisture absorption. Place your filament spool in the bag and then add couple of silica gel packs to get rid of the air.

Filament impurities

Impurities in the plastic is the biggest issue when choosing filament. Chemical impurities cause poor melted plastic viscosity and debris will plug up the extruder nozzle. A blocked nozzle can cause severe problems. The print will not only stop working, wasting time and money , but it may also mean dismantling the extruder and cleaning it. It is believed that plugged nozzles and low-quality filament are in a close relationship. Although you may want to cut costs on filament at the beginning, cheaper filament could be more expensive in the end. It will save you many headaches when you purchase decently priced filament that is high-rated.
