GlueDart. Glue Pen With Electric Motor Extruder
Intro: GlueDart. Glue Pen With Electric Motor Extruder
Today, glue guns are widely used in everyday life and in production. They are used by makers and builders, home masters and professionals. Makers of the whole world use glue guns for gluing various surfaces (textiles, paper, plastic, wood, etc.). The glue gun is indispensable in many types of creativity and needlework (quilling, scrapbooking, floristry, decoration, etc.).
I often use the glue gun in my work. And I have wanted to have a glue gun, which will produce a drop of glue and dosage will be easier to use, such as a 3d pen.
I created a model of a glue pen with an electric extruder. I took the heater out of the ordinary glue gun. The body and all the mechanical parts are created in Fusion 360. After that, I printed all the details on the 3d printer.
STEP 1: List of Components
3d printing:
Body (2 parts)
Motor part
Rollers
Button Holder
Stand for glue pen
Electronic and mechanical components:
30RPM Mini DC Metal Gear Motor
Button TACT-34N-F
Charger module LI-CHARGER-MicroUSB
Battery LP302030
8 Screws: Self-tapping screws M3X10
2 Hexagon socket head cap screws M3X16
STEP 2: 3d Printing
Print all 3D print components
I attach the STL files
NB! Do not use PLA plastics, as it can deform when heated
STEP 3: Electric Parts Assembly
Connect the charger module to the battery
Connect it to the micro-adapter
The capacity of this battery ensures continuous operation for 1 hour
If the glue pen should work for a longer time, it will be better to use a more powerful external battery.
STEP 4: Button Holder
Put the button in the holder
Solder the wire length of 10 cm
Glue the button holder to the case at the level of the U-hole
STEP 5: Motor Part Assembly
Assemble the motor part
Screw rollers and motor
Fix the motor part to the body with screws
STEP 6: Extruder Assembly
Place the charger module with battery
One button wire connect to the motor
The second wire of the button is soldered to the board
The second motor wire is soldered to the board
Press the button and check the direction of the feed roller
STEP 7: Final Assembly
Insert the heating part
Collect the body completely with screws
STEP 8: Go to Work!
Connect the glue stick to the mains
Wait when warmed up and get to work
I tested a glue gun when assembling a kitchen set - a bowl and a napkin

GlueDart works with 11 mm glue rods
I want to create a glue pen for 7 mm rods and 12-volt power.

I think standard heater from 220V glue guns will not work, you need battery operated glue gun as a source of heating unit?

Excellent! I especially like the 3D printed spring for the roller.

Thanks!

Wow, that's an excellent design for a great idea. I've added this to my project queue. I'll be adding a speed control for the motor to better control the glue dispense amount. I wish I had a 3D printer :(
Thanks :)

I own a battery-powered Bosch 7mm glue pen, and I was thinking to motorized it. Your great design gave me some ideas. Thanks!
TanyaAkinora 6 years ago
Thank you! Wait a little. Now I'm doing a 7mm version of the glue pen.

Great! What base are you using, for the nozzle?
TanyaAkinora 6 years ago
In the heater, the nozzle is connected to the main body and I use the heater from an ordinary glue gun.
fmafma 6 years ago
But are you using a heater from a 7mm hotgun, which have a smaller nozzle?
TanyaAkinora 6 years ago
Now I'm working on a 7mm version of a glue gun. I want to make temperature and extrusion speed adjustment.

As your are designing a 7mm version, could you have the body made from 2 parts, to be able to 3D-print the front part with a temperature proof filament, and the rear part with standard PLA?
I ask this because we recently found a nice filament which can resist up to 110°C and can be extruded at 250°C:

but it is quite expensive :o/
TanyaAkinora 6 years ago
I'll think about it. We have a local manufacturer's nylon.

would it be possible to use some sort of force sensitive button or pot so that you could vary the speed?
TanyaAkinora 6 years ago
Yes, it is possible. But this will require a more complex electronic part.

wow!!! Very nicely done
