Understanding Adhesives in 3D Printing
Adhesives play a crucial role in ensuring successful 3D printings, such as keeping the first layer firmly attached to the build plate. The use of adhesive types like glue sticks can enhance bed adhesion, particularly on glass surfaces.
Selecting the Right Glue Stick
When choosing a glue stick for 3D printing, opt for a non-toxic and safe product like Elmer’s Disappearing Purple Glue Stick. This adhesive not only improves the adherence of printed objects but is also easy to apply and remove once printing is complete.
Preparing the Build Plate
Clean the Surface: Begin by thoroughly cleaning the build plate. Use isopropyl alcohol or soap and water to remove dust, grease, or residues from previous prints.
- Apply the Glue: Take your chosen glue stick and evenly apply a thin layer over the area of the build plate where the print will take place. Ensure full coverage without excess buildup, which can lead to messy prints.
Setting Up Your Printer
Level the Print Bed: Leveling ensures that the distance between the nozzle and build plate is optimal, keeping consistent contact for better adhesion. Adjust the printer’s leveling knobs to achieve a balanced surface.
- Adjust Nozzle Height: Carefully set the nozzle at an appropriate height relative to the build plate. The nozzle should be close enough to allow filament to extrude smoothly onto the surface without scraping or damaging previous layers.
Monitoring the Print Process
Check Initial Layer Adhesion: As the print starts, observe the first layer. It should stick to the build plate without being squished. If it lifts or curls, the coverage or height may need adjusting.
- Intervening if Necessary: If results are unsatisfactory, pause the print. Re-evaluate the glue application and bed leveling, and make necessary corrections to improve adhesion.
Removing the Finished Print
After the print has completed, let it cool slightly. The glue stick will allow for easier removal compared to prints without adhesive. Gently lift the print from the plate, ensuring not to damage the object or the build surface.
FAQ
1. Can I use any glue stick, or is a specific brand needed?
While various glue sticks can work, using a brand like Elmer’s Disappearing Purple Glue Stick is recommended due to its efficacy and ease of removal.
2. How do I know if the glue stick is applied correctly?
A properly applied glue stick should create an even, thin layer over the intended area of the build plate. You should not see excess glue pooling anywhere; the surface should still appear mostly clear.
3. What do I do if my prints keep failing to stick?
If prints are not adhering, check the bed level and nozzle height once more. You may also want to clean the build plate again or apply a fresh layer of glue for improved adhesion.
