3D Printer or Pen: Dive into a Detailed Showdown!

Technological advances dazzle us every moment, and the realm of 3D printing is no stranger to such evolution. A device that’s piqued my interest lately is the 3D pen. Curiosity bubbles up when thinking about how it stacks against its larger counterpart – the 3D printer. Though both have distinctive purposes, they operate based on a similar principle. This piece paints a vivid picture, contrasting these two gems of technology, and delves deep into their frequently asked queries.


A 3D pen is essentially a miniaturized version of the 3D printer, finding favor among tech fans and craft lovers alike. The 3D printer, conversely, takes up a more dominant space in the 3D printing universe, given its widespread admiration and incredibly versatile applications.

Dive further into this narrative for a thorough examination that commences from elementary components and delves deeper into enlightening segments. By this read’s finale, the fog of uncertainty will hopefully lift, unlike when I embarked on this journey.

Understanding 3D Printing Devices:

What is a 3D Printer?

A 3D printer, in essence, is a marvel that crafts 3D creations layer-by-layer, employing an array of methods – from melting thermoplastics using intense heat to solidifying photopolymer resin with robust light sources. Contrary to popular belief, there isn’t just one kind of 3D printer. I’ll shed light on the two primary types: FDM 3D printer and SLA 3D printer.

Exploring the FDM 3D Printer:

Fused Deposition Modelling (FDM) is a technique that leans on thermoplastic materials like ABS, PLA, or PETG for crafting 3D models. Each is versatile and addresses specific applications.

At its core, almost all 3D printers, especially the FDM ones, incorporate:

– A structure shaping the printer.
– An extrusion point for the filament.
– Stepper motor(s) ensuring extrusion.
– A construction area where creation ensues.

In FDM, the selected material melts inside the 3D printer. The liquefied substance is then pushed out and onto a platform, solidifying to achieve its final form. The procedure iterates layer by layer until a meticulous 3D creation emerges. Once your creation is ready, a post-processing phase refines the model to perfection.

Diving into SLA 3D Printers:

Stereolithography Apparatus (SLA) employs a UV laser in tandem with a light-sensitive liquid resin to yield impeccable results.

Distinct from FDM printers, SLA printers excel in precision and offer superior surface finishes. A typical SLA printer houses:

– A reservoir holding the clear plastic resin.
– A movable platform inside the reservoir.
– A potent laser steering the layer-wise creation.
– A digital dashboard for comprehensive control.

Digital Light Processing (DLP), an SLA-adjacent technology, uses projector screens over lasers for 3D printing. Many view DLP as a superior variant of traditional SLA. The expansive build size of SLA printers without compromising on detail makes them preferable to FDM models.

3D Printers: Their Purpose & Domain

3D printers have etched their mark in myriad sectors, making it challenging to encapsulate their full spectrum of applications. From healthcare and art to automotive and DIY projects, 3D printing amplifies every domain it touches.

Introduction to 3D Pens:

A 3D pen, akin to its larger counterpart, relies on thermoplastic material that emerges from its tip. Unlike conventional pens using ink, it uses popular filaments like PLA or ABS and is crafted with user safety in mind.

3D Pens: Where Do They Shine?

Although not as ubiquitous as 3D printers, 3D pens have carved a niche in sectors like education, art, fashion, and even quick fixes to 3D printed models.

3D Printer vs 3D Pen: A Face-off

Let’s scrutinize how 3D printers and pens measure against each other, dissecting their attributes in a descriptive manner.

Quality: Unsurprisingly, a 3D printer trumps a 3D pen in producing superior quality objects. While some high-end 3D pens can craft impressive models, the precision and capabilities of a 3D printer remain unparalleled.

Strength: 3D printers, with their intricate settings and robust material compatibility, produce far sturdier objects than 3D pens.

Ease of Use: Though both have their learning curves, modern 3D printers, with myriad tutorials available,
