What is in the Box?

7tech 3d pen boxThere are a number of accessories that come in the box. These include:

3D Printing Pen

The main accessory in the box is the 7Tech 3D pen. The pen is blue in color and looks like a standard glue pen. The pen is fitted with an LCD display on which you can select different settings such as flow speed, temperature, and others. The pen feels somewhat like a standard glue pen and weighs a mere 65gm. The ergonomics of the pen allow you to create 3D objects in a comfortable writing position.

Power Cable

The box comes with a standard 110-240 volts power adapter. You can power the pen by fitting the cable in any standard power socket.

ABS Filament

ABS filament refers to a thin type of plastic wire that is used in 3D pens. The filament is inserted in the pen and then melts when the pen is heated. On melting, the filament turns to molten plastic, which is used to create the 3D objects.

The filament comes in different colors. In the 7tech box, there are three color filaments to get started with. You can think of the filament as the refill ink for a pen.

Introduction Manual

You need to go through the manual to learn how to operate the pen. The manual is available in every box and is especially useful for new beginners. You should also check the safety instructions indicated in the 7tech 3D pen instructions manual. For example, the pen has a powerful heating element that can get the nozzle to reach temperatures of up to 230∞C.

Design of the 7Tech 3D Drawing Pen

If you are interested in 3D printing, the only tool you need is the best 3D pen. However, choosing the right pen is challenging as new 3D pens enter the market and the old ones get improved.

The 7TECH 3D Drawing Pen Ver. 2015 is one of the best 3D pens in the market. The pen is designed with the end-user in mind and uses fused deposition modeling like is used in 3D printers.

Features of 7Tech 3D Drawing Pen

While the 7Tech 3D printing pen is compact and small, it has a host of features that make it an ideal pen for beginners and experienced artists. Below is an overview of the features of the pen.

Temperature Control

The pen can use different types of plastic filaments. These filaments have different melting points. You can adjust the temperature to reach the melting point of the filament you are using.

Speed Control

7tech 3d Pen with speed controlYou can control the speed of the 7Tech 3D Printing Pen using your finger. The one-finger speed control allows you to slow down or increase the speed of the flow of molten plastic.

If you are creating intricate designs, slow down the speed to have more time to maneuver the pen. On the flip side, if you want to quickly complete hours of repetitive work, speed up the flow of the molten plastic.

Jam Detection and Unclogging Mechanism

3D printing pens can get clogged, just like is the case with traditional printers. The good news is that the 7tech 3D pen has jam detection mechanisms. When there is a jam, an error message is automatically displayed on the LCD display. To unclog the jam, simply reverse the motion of the filament by using the speed button.

Auto Standby Mode

To save power and ensure the heating element stays durable, there is an auto-standby mode. With this feature, the heating element of the pen automatically switches off after 5 minutes of inactivity.

Dual Filament Operations

There are two types of filaments for 3D pens in the market. These pens only work with specific filaments. The 7Tech 3D Pen works with both 1.75mm PLA and ABS filaments. With this pen, you can buy any filament you want, depending on your budget.

Silent Operation

One of the disadvantages of buying cheap 3D pens is that they can be noisy when you are using them. The noise can distract your creative process. The 7Tech 3D pen does not vibrate nor produce noise, even when in use for hours.

Safety Features

You can use the 7tech pen at home or in the office without worrying about interruptions. The pen has an auto-standby mode which enables it to temporarily shut off when you leave it idle for more than 5 minutes.

Cons of the 7Tech 3D Pen

I personally loved my experience with using this pen. Clearly, many other users also love the pen from the reviews on Amazon. However, there are a few concerns some customers had with the pen. These include:

  • Although the pen comes with 3 filament strands of 3 colors (pink, blue and white), these are never enough. You should, therefore, add an extra filament package with other colors when making your order.
  • The pen nozzle can get extremely hot. It heats up to 240 degrees. Therefore, be careful when using the pen where there are children who can easily touch it.
  • Children below 8 years should not use the pen due to the burning hazard. Children above 8 years should only use the pen under adult supervision.
