How does a 3D pen work?

Artists across the world got a major boost with the influx of 3D pens in the market. Creativity stepped up a notch higher. And now adults as well as the young ones can venture into 3D art at the comfort of their homes. 

If you’re looking to know how they work, you may be in the market for a 3D pen, or you’ve just bought one.. But if you are just starting out, have a look at this detailed buying guide by Reviews Rabbit. Order your favorite 3D pen and I’ll help you get started. 

What is a 3D pen and how does it work?

A 3D pen closely resembles a ballpoint pen. The major difference is that, whereas the ballpoint pen uses ink, the 3Dpen uses plastic. With a ballpoint pen, you can only write in 2D mode. The 3D pen allows you to write in 3D, or rather create 3D objects.

The plastic, herein referred to as the filament is fed into the rear end of the pen. By pressing the button on the side of the pen, you drive a motor, which pulls the filament through the pen. Once the filament hits the bottom of the pen, it is heated up so that it flows through the tip in molten form. 

In addition to the motor button, most 3D pens come with two other buttons:

  • A button for unloading the filament from the pen. Yes! The filament is not stored within the pen as is the case with ballpoint or fountain pens. 
  •  A button for controlling the speed with which the plastic flows out of the nozzle. The faster the speed, the narrower the molten strand – and the vice versa is true.

To use the 3D pen, hold it like a normal pen. Press the printing button and wait for about 30 seconds for the plastic to start oozing out. Remember the nozzle is hot. Don’t attempt touching it. You will badly burn your fingers. Move the nozzle to and fro the template in line with what you are drawing. The nozzle doesn’t have to be in tight contact with the surface as is the case with the normal pen. Lift it off slightly to allow the plastic to flawlessly flow out.    

Is a 3D pen worth it?

In my opinion, the 3D pen is a very valuable tool for artists, children, and DIYers. Artists are able to advance their creativity into the 3D realm and create whatever object their mind thinks of. For children, it is a really reasonable playing tool as it improves their creativity. They are able to create the toy that they want to play with, rather than just get a complete toy from the stores. DIY enthusiasts will definitely find the 3D pen useful in fixing damaged objects or adding decorations to everyday household items. 

How do you use a 3D pen?

The best way to get started is by using a template for penning over. Draw the shape you want on the template using ink or pencil. Once you deposit the plastic onto the template, give it time to cool and harden. Handling it immediately may considerably distort your work of art. To keep your work neat, consider releasing the motor button some 2 or 3 seconds before the end of a specific line you are drawing. This is due to the fact that the plastic keeps oozing out for sometime after you release the button. 

What do you draw on with a 3D pen?

Experienced artists mostly use 3D pens free-style, meaning they directly create their 3D imaginations without the need of a template. To get to that level, consider drawing your objects on a piece of paper on which you have sketched the faces of the desired object. In case you are lost on what exactly to draw, feel free to search online for 3D pen stencils. Kick off your artistic journey in style.

Why do squirrels chase each other?

If there is one thing that pretty much every human on earth is familiar with it’s animals chasing each other. Be it dogs, cats, monkeys, rabbits, or dolphins – we’ve seen it all. And we usually shrug it off as animal play.

Why do squirrels chase each other

But why do squirrels chase each other around trees? Is it also normal play like other animals? Or is there some more sinister reason behind it? Let us find out.

1. Territorial dispute

One major reason why squirrels chase each other is to stand out amongst the others as the boss. Several squirrel species are territorial – meaning they try with all their might to protect their territory from intrusion by other squirrels. 

Territorial behavior in animals has two major goals:

  • To allow a male to mate its herd of females without disturbance – this involves males chasing males. Males have been shown to have a territorial range of about 75 yards.
  • To raise offspring without undue competition – this involves females chasing females, especially when the potential nesting sites are limited

to protect their territory from intrusion by other squirrels

So when an intruding squirrel tries to feed in an area dominated by another squirrel, a vivacious chase ensues. The dominant squirrel additionally nips at the other squirrels.

Note that such territorial behavior is not seen in all species of squirrels. The northern flying squirrels and American red squirrels are known to be territorial while the fox squirrel and grey squirrels are not territorial.

If you are a keen observer, you must have noticed that other chases are more romantic as opposed to aggressive. That leads us to the second reason for squirrels chasing each other.

2. Looking for a mate

Do squirrels fight with each other during the mating season? Experts tell us that mating started some 1.1 billion years ago when mother nature saw the need to increase genetic variation through the fusion of sex cells.  An economic problem immediately arose. You see, female species have a limited number of eggs while males have an unlimited sperm count.

 To produce an offspring, you need only sperm to fertilize one egg. Therefore, supply and demand forces greatly increased the cost of female eggs. And once the male mates with the female, the female remains “locked” for some period as the fertilization process ensues. This leaves the male with no other option but to chase around some more females. 

Male squirrels chase the females

Philosophy aside, the chase has been there and will always be. The mating chase in squirrels is a bit slow-paced compared to the territorial chase. Male squirrels chase the females in a unique technique that allows them to evaluate the reproductive state of the females. 

The majority of squirrels attain sexual maturity around the age of 1 year.  As a female squirrel approaches oestrus, it emits attractive scents that catch the attention of several males, including those from other territories.

Once the males meet on the mating arena, they chase and fight to claim dominance. The winning male wins the hearts of the female squirrels. Even so, the potential bachelor is not allowed to mate that easily. 

The female squirrel intentionally runs off to see if the potential suitor is really determined. That is why you will usually spot two squirrels in a somewhat endless chase around trees and across the fields. Copulation occurs once the female is convinced with the persistence of the male. 

3. Child’s play

They said “as playful as kittens” – but we do understand that the playful nature of young animals extends to several other species – you must have spotted young squirrels playing.

Squirrels really love chestnuts

It is not uncommon to spot two or more young squirrels fighting playfully and chasing each other. This helps them to develop mobility skills and strength.   

To sum it up

Chasing among squirrels depends on the species, age, and sex of squirrels, and the season. Use this knowledge to know how to best position yourself as you hunt the squirrels.
