Before diving deeper into Prusa 3D printers, you should select the type of 3D printing tech that suits your needs since the two popular variations are very different.

Types of 3D Printing Technology

Full PCB Manufacturing


FFF tech, which also goes by the name FDM technology, is a type of 3D printing technology that involves the utilization of melted plastic filament which extrudes from a unique 3D printing nozzle. To better explain this, imagine a huge and highly accurate glue gun that carefully and precisely layers the materials before they cool down rapidly to generate a solid model. By far, this type of technology is the most utilized in the 3D printing industry.

FFF tech has a couple of advantages which include:

  • A huge print volume
  • Easier manipulation
  • Easier use

Moreover, the filaments that technicians use in these printers come in many different materials and colors, which also breed variety per functionality. What that means is that different filaments (according to their materials) fit into different application areas.

However, even though FFF tech is excellent and beneficial, it still has one major con, which is that:

  • After printing, this tech develops 3D objects with visible 3D print layers – these visible 3D print layers may be a considerable concern when producing tiny and detailed 3D prints.

SLA Tech

SLA tech, which also goes by the name DLP or MSLA tech, is a type of 3D printing technology which utilizes liquid resin, hardened using UV light to make 3D prints.

SLA technology has a couple of advantages. However, its primary benefit is:

  • SLA tech prints more refined and smaller 3D prints compared to FF technology.

Moreover, the newer versions of SLA printers have the ability to print 3D objects pretty fast compared to their predecessors.

However, even though this 3D tech is pretty efficient, it still has some advantages, which include the following:

  • Having a smaller printing volume compared to FFF tech
  • It is also challenging to manipulate the materials that technicians utilize in this technology

Moreover, the 3D print material of SLA is pretty sticky, and it often comes with an unpleasant smell.

After printing 3D objects using this technology, you must provide aftercare to the models to help them heal well. Firstly, you have to wash away the uncured resin from the prints. After this, you have to expose the print to more ultraviolet light to cure it completely.

As you can see, FFF and SLA tech are pretty different. Therefore, you must carefully consider the type of tech you want to utilize on your project. After this, you can select the type of Prusa three-dimensional printer under the category you choose to use on your 3D printing project.

Selecting Prusa 3D FFF Printers

Prusa i3 3D Printer

Every FFF printer in the market has two primary components:

  • A print head with a printing nozzle that efficiently extrudes melted filament.
  • The extruded melted filament layers up according to the 3D printing model design generating a 3D print. The 3D print lies on a printing bed which is the second primary component

FFF tech also has subcategories that group various FFF tech 3D printers according to how they move these two primary components against each other. As of now, the most popular category is known as Cartesian construction.

Cartesian Construction

Under this category, the printing bed moves backward and forward, and the print head, on the other hand, moves efficiently above the printing head. Moreover, as the printing head moves, it also slides on horizontal and vertical axes, left-right and up-down.

Of course other 3D printing construction types exist which include polar, corexy, delta et cetera. However, these construction types bear different movement patterns. For instance, the printing bed may be rotating, moving up and down, or rotating.

Under FFF 3D printing technology, the most popular Prusa three-dimensional printer is the Prusa i3 MK3S.
