Filament Related FAQ

 

Filament in General

 

What do we consider a premium filament?

  • First grade raw materials
  • No Micro-bubbles
  • Non-toxic or no otherwise harmful colorants
  • No dangerous plastic conditioners like Phthalates
  • No harmful other additive (Tests for RoHS 1.0 + 2.0)
  • No or very little odor when printing
  • Even melt flow when printed
  • Evenly mixed and consistently extruded when produced
  • Consistency Diameter with a defined and guaranteed variance
  • Clear processing parameters guidelines

Why are accurate diameter tolerances important?

  • Accuracy of printing as Slicer is not aware of diameter changes which leads to little or too much material being deposited
  • Visibly smoother printed surfaces

How long can I print with one spool of ExcelFil™?

A spool of ExcelFil™ contains a net weight of 1kg filament. Depending on the nominal diameter of the purchased filament the length of the filament is calculated as following:

Length = Mass / ( Density x PI x ( Diameter / 2 )^2 )

The density for our PLA filament is 1.24g/cm3 and 1.04g/cm3 for ABS.

Hence a 1 kg spool of 3mm PLA yields in average 117 meters. A 1 kg spool of 1.75mm PLA yields in average 345 meters. A 1 kg spool of 3mm ABS yields in average 140 meters. A 1 kg spool of 1.75mm ABS yields in average 411 meters.

EVO has about 232.588 m on each spool of 1.75mm.

An iPhone cover for example takes about 1.14m to print in 3mm PLA. So to give you an idea, you can print a good 100 pieces with one spool!

Why do print temperatures vary for different colored Filament?

Different color pigments used influence the melting and glass transition temperature points of ABS and PLA. This is the reason that you have to try-and-error the optimal print temperature when you buy a new role of filament. We have spent a lot of time to properly characterize the filament we sell and our support database has pretty exact recommendations on which temperatures are optimal for each and every different variation.

Is ExcelFil an OEM product from a random factory?

  • We carefully researched our own formula to produce ExcelFil Filament
  • We hand-picked high quality raw materials from global industry leaders
  • First Grade material, no recycled polymers
  • We are a shared production manufacturing company

Aren’t all filaments made from the same materials?

  • Most filament are made from different compounds.
  • Voltivo ExcelFil uses approved material with the highest quality compound for our filaments.
  • We constantly research on improvement of our material compositions

I have seen other brands with a wide temperature range setting, why your temperature gap is so small?

  • High purity/non-recycled materials allow the plastic to melt at lower, well defined temperatures
  • We have tested and researched our material with the best melting temperature with +/- 6-10 degree C
  • For best printing in quality please view our temperature guide

How does Voltivo ensure their product quality?

  • Primary High Precision Laser measurement system to alert inconsistency
  • Diameter Consistency of at least +/-0.05mm
  • Secondary Quality check at the production line
  • Tertiary print tests of every batch before release for shipment

After opening the vacuum packaging, how long can the filament last?

  • Depends on the humidity of your surrounding environment
  • Filaments tend to easily absorb moisture
  • For low humidity environment it will last for months
  • We always suggest to properly store your filaments to preserved the best quality
  • Storing them in a airtight container with sufficient desiccant will extend the useful life

How to choose PLA or ABS for different applications?

ABS can sustain higher temperatures before it softens It also is better suited for outdoor applications in general PLA, in general is easier to print and best suited for design prototypes for example

Why do I experience cracking / fracture lines on my print?

  • Often, this is the result of incorrect temperature settings of the bed, extruder
  • Also, a build environment that is not shielded from drafts or temperature changes will cause inconsistent cooling of the print and cracks in the final model.
  • This effect also can result from low grade polymers which have have high shrinkage factors

How to store filament the best possible way?

  • An active dehumidifier is the best (Like a photo equipment cabinet)
  • Store the filament in a cold dry compartment will prolong its quality
  • Store them in a container with silica gel packets
  • Using a ziploc bag and Silica gel packets

Should I use caliper to measure the diameter every time I print?

  • With Voltivo ExcelFil you can print with peace of mind every time as our filament diameters are very consistent
  • We do suggest making a habit every time you feed in a new spool of filament

Is ExcelFil Filament compatible with other brands of printer?

What is the difference between PLA and ABS?

PLA is a polymer produced from renewable resources like maize and sugar cane. It in general is easier to print, does not require a heated bed and warps less. It is bio-degradable in the right conditions.

ABS on the other hand is made from fossil fuels, is much harder and more impact resistant, hence often used for mechanical parts or parts to be exposed to the elements.

3D printer and nozzle related

 

Can filaments damage the nozzle?

  • In general, quality filament with proper heat setting will not damage printer nozzle.
  • Low cost, impure filaments may contained dirty substance that will cause cloggage
  • Some compound Materials like Carbon Fibre or Metal Powders will dramatically accelerate wear and tear on brass nozzles

What to do if my nozzle clogged?

  • Check your recommended melting temperature of your filament.
  • Impurities in low quality filament, larger than your nozzle size may be blocking the nozzle
  • Consult your printer manufacturer

Are metal or other compound filaments harmful to my nozzle?

If the ration of polymer to metal compound are too high, brass nozzles, which most current printers use, will greatly suffer. You will be able to see that effect after a short while. Our ExcelFil TECH series has a carefully balanced polymer to compound ratio, to protect your nozzles from these effects.

How can I prolong the life of my nozzle?

  • Voltivo Filament Cleaner will prevent small particle or dirt clogging printer nozzles in the long run
  • Only use Premium filament
  • Use proper heat and speed setting
