Naming convention for 3D-print settings

by CreativeTools

Many 3D printer operators around the world are making #3DBenchy boats (http://www.thingiverse.com/thing:763622 ) to test and compare their results and 3D-print settings. It would therefore be good to define a simple naming convention to describe 3D-print values used to make #3DBenchys.

Please refer to the suggested list below and copy/paste it into the description of your #3DBenchy makes. Feel free to suggest any improvements to the list items and naming. We will gladly modify and improve the list accordingly.

3D-print settings

  • 3D-print method:
  • Material:
  • Layer height/thickness:
  • Infill percentage:
  • Number of perimeters/shells:
  • Print duration:
  • Print nozzle temperature:
  • Print speed:
  • Print-bed surface type:
  • Print-bed-adhesion type:
  • Print-bed temperature:
  • Support structures:
  • Post-processing:

Item descriptions and values

3D-print method:

Almost all 3D-printers use the same basic method - adding material along a continuous axis, layer by layer. Apart from this, they can be roughly categorised as follows:

  • Material extrusion: This is a very common and accessible method where the 3D printer feeds material through a small nozzle hole. Very often the material is made of filament stock (hard thermoplastic) fed into a heated nozzle where it melts and extrudes through a small bore. It can also be any "semi-fluid" material that can be pushed and extruded through a hole, such as clay, silicone, etc.
  • Vat photopolymerization: This method uses a light-source (moving laser dots or pixel-matrix of a projector) to selectively harden liquid resin placed in a container.
  • Material jetting: This method is very similar to a common 2D ink-jet paper printer where the ink in the print cartridge is replaced by liquid plastic (liquid resin). When the small droplets exit the printhead, the are hardened by a UV light source.
  • Binder jetting: This method is very similar to the Material jetting described above because it uses ink-jet print heads to spread a binder (glue) onto a power-filled bed.
  • Powder bed fusion: In this method thin layers of powder (plastic, glas, metal, etc) are selectively melted by an energy source - such as a laser beam.
  • Sheet lamination: This method builds 3D models by gluing sheets of material (plastic, paper, etc) together. Each sheet is cut along the perimeter of the sliced 3D model.
  • Directed energy deposition: This method effectively "melts" or "jets" material additively into a three-dimensional shape. By its nature direct energy deposition can create models in a non-layered fashion.


The type of material used to build the printed part. PLA, ABS, Polyamide, TPU, Clay, Metal, paper, etc.

Layer height/thickness:

The vertical size (also called height or thickness) of each layer. Most commonly all layers in a 3D print are of the same dimension. Maybe with exception of the first layer. The value for this list item is usually described in mm or microns. (also called micrometre, which is one millionth of a metre). Below are commonly used values.

  • 0.05 mm (one twentieth of a millimeter) equals 50 microns
  • 0.1 mm (one tenth of a millimeter) equals 100 microns
  • 0.2 mm (one fifth of a millimeter) equals 200 microns
  • 0.3 mm (one third of a millimeter) equals 300 microns

Infill percentage:

For fused filament fabrication 3D printers (FFF and also called FDM) this value defines the amount of material used to fill the inside of an object past the borders of the outer perimeter perimeter/shell line(s). The value is usually defined by a percentage (%). Low values yield fast but "weaker" parts. Higher values yield longer prints and stronger parts.

For most other methods of 3D printing, such as liquid-resin- and powder-based, there is no "simple" way to make the inside of a part sparse. Which means that almost every 3D-printed part made with this method (SLA, SLS, LOM, etc) are 100% solid. If you use such methods 3D-printing your #3DBenchy, please define 100% or write the word solid.

Number of perimeters/shells:

This value is only suitable for material-extrusion methods where each layer's outer perimeter border is defined by one or more continuous extrusion lines.

Print duration:

The time in minutes and seconds the printer took to make the model until it stopped. Any eventual manual post processing time is not included in this value.

Print nozzle temperature:

This value is only suitable for material-extrusion (FFF/FDM). It defines in °C the normal working temperature of the nozzle.

Print nozzle bore:

This value is only suitable for material-extrusion. It defines the inner diameter of the extrusion nozzle's exit hole.

Print speed:

For material-extrusion 3D printers this value can be defined in mm/second as the standard travel-speed in X and Y while the nozzle extrudes. For photopolymerization 3D printers that use a projector, this value can be defined as seconds/layer.

Print-bed surface type:

The type of surface material of the build plate to which the first layer adheres.

Print-bed-adhesion type:

Defines if the bottom part of the 3D model is adapted by the 3D printing software to achieve optimal adhesion to the print-bed. Such as raft, brim or none.

Print-bed temperature:

The temperature in °C of the print-bed during 3D-print.

Support structures:

Defines if the model was printed with structures for supporting overhang areas.


Describes if any manual or automatic post processing was applied after 3D-print
