Why would I need to use hairspray for 3D printing?
Hairspray can solve the trickiest dilemma of 3D printing – it helps the model you are printing both stick tightly to the bed, and also easily release when it is finished, without damaging the part or the printing bed surface.
Hairspray provides a sticky surface for better adhesion
A thin layer of hairspray on the printing bed surface provides a tacky structure to increase your chances of getting perfect adhesion the first time.
One problem that many people have while 3D printing is poor adhesion. It is crucial that your first layer attaches to the bed so that the rest of your print can stay in place and come out the way you planned.
Hairspray prevents damage to the 3D printer bed surface
Using hairspray on your 3D printer bed prevents damage by creating a barrier between the bed surface and the finished model.
Even if your print initially adheres correctly, you may face another common adhesion problem that can happen just as you’ve finished printing, and the consequences are worse than just one bungled print job.
Sometimes a piece of your glass bed can seem to glue itself to your filament, so when your print is done and you go to remove the part you have just printed, a chunk of your glass bed can break off with it.
If this happens, you’ll need to replace your entire printing bed plate before you can use the machine again. The replacement can be time-consuming, and purchasing a whole new printing bed is expensive.
Even a thin layer of hairspray on the printing bed will create a barrier between the bed surface and the part you are printing. That way when you remove the part, it will separate easily from the bed, leaving you with a functional surface to print on again in the future.
Is hairspray the best choice for 3D printing?
3D printing enthusiasts, faced with these adhesion issues, have come up with a variety of solutions.
Some people use specific adhesive sprays, but those can be costly.
Glue sticks are often recommended for 3D printers, but they take longer to apply than hairspray, and even with the extra time, it’s hard to get an even layer. Glue sticks can also be messy and difficult to clean up after.
Hairspray is inexpensive, easy to use, and extremely effective at both making sure your parts stick to the bed, and also serving as a separator so that the part will lift from the bed easily and without damage.
How do I use hairspray for 3D printing?
To use hairspray on your 3D printer, first remove the printing bed surface from the printer. If you are using a printer that does not have a removable bed, be careful to spray only on the printing surface and avoid the rest of your machine.
Spray the hairspray directly onto the bed in a thin, even layer. Wait about one minute for the hairspray to dry, then carefully put the bed back into place.
The surface of your bed should now be slightly sticky to the touch and ready for printing.
You can do this process once, and then you only need to reapply another layer of hairspray every 5-10 prints.
Using this technique with a printer that has a heated bed will give you very reliable returns. If your printer does not have a heated bed, an effective adhesion strategy is even more important to ensure proper results, so a carefully selected can of hairspray can save you a lot of time and effort.
Can I use any hairspray on a 3D printer?
You can use any hairspray on a 3D printer. All kinds of hairspray will help provide better adhesion and prevent damage to the printer bed surface. You’ll want to consider cost and strength when choosing which hairspray to purchase for use on your 3D printer to make sure you find the one that meets your needs the best.
What kind of hairspray should I use for 3D printing?
You should always use strong, unscented hairspray for 3D printing. Look for hairspray with labels like “extra strength” to ensure that the hairspray will be substantial enough to create a durable printing surface. Make sure that the hairspray is also unscented so that it will do the job without any ingredients that might interfere with the printing.
