Slicers and user interfaces for 3D printers

Draft

Introduction

A so-called slicer takes a3D drawing (most often in .STL format) and translates this model into individual layers. It then generates the machine code that the printer will use for printing.

3D printers can be either controlled through a small on-board control screen or through a (USB) interface with a computer or through both.User interface software allows a user to send a machine code file from the computer to the 3D printer, change some parameters on run time, and move around axis manually etc.

Some programs, like Netfabb engine, combine the functionality of a slicer and a user interface/manual control software.

Slicer software

Current low-end 3D printers extrude plastic like ABS or PLA from filament. The filament is pulled into the extruder and heated in its nozzle (hot end) and finally deposited. The extruder (also called print-head) will move while extruding, or move (or jump) without extruding.

A slicer program allows to calibrate printer settings for various types of "areas to print", like:

• extrusion speed (rotations / minute)
• head speed
• temperature
• Fan on/off

Furthermore, the program allows to define:

• wall thickness
• fill patterns
• extrusion speed, head speed and temperature per type of area
• Etc.

Deposited filament for a layer or a section of a layer depends on extrusion speed, head movement speed, and temperature. In addition, factors like movement patterns, plastic brand, fan on/off etc. also have an influence on the design.

List of slicer software

• Skeinforge
  • Supports various machines, e.g. RepRap machines, RapMan, Ultimaker, etc.

• BFB Axon
  • Frontend for skeinforge, works with BFB machines only

• Kisslicer
  • Quote: is a fast, easy-to-use, cross-platform program that takes 3D files (STL) and generates path information (G-code) for a 3D Printer. The FREE version has all the features needed for the hobbyist who uses a single-head machine. The PRO version essentially adds multi-head and multi-model printing.
  • For RepRap printers

• Repsnapper

• Slic3r
  • For RepRap printers
