Has anybody tried and had luck with particleboard? I really wanted 1/4 MDF but was having trouble finding it. I ended up with 3/8 particleboard. I messed around with a few settings and only got through it at six passes, full power, and 130 speed. That would amount to days of cutting time for this project.
I didn’t try changing the focus between passes.
Or does anybody have a great idea for creating hollow letters? Basically a letter shaped box. The front and back can be the 1/8 MDF but I need a way to make the walls thicker.
The letters are 11" high and the bars are about 1.5" wide. I need the to be 1 - 1.5" deep to hold the sockets. The back of each letter will be screwed to two horizontal slats.
It will be transported ten hours in a trailer with lots of other gear and setup in 100+ degree heat and full sun. I may end up with the particle board but just cutting out one layer of the M and N was almost three hours.
No one’s addressed yet the question on using particle board itself–I would avoid it, until you confirm that the adhesive/bonding agent was used to hold all the particles together is safe to laser–always better to assume there’s a risk that nasty toxins could be released into the air & breathed in when lasered… And just because you may have a filter does not mean it is designed for the type of volatiles/toxins you may be releasing with the sanding/heat gun/laser being used for the process!
And for the project–for the size of the letters & sign–my first choice would be a jig saw and forstner bits for the sockets (e.g. what they use for euro hinges for cabinet doors). Then particle board would be a decent option! Or “hardboard”…
The MDF and EVA sandwich worked well enough for this project. Even though I do four passes on the EVA it is still less than ten minutes rather than the three hours for the particleboard.
I was considering starting from scratch with CNC as I’m currently setting up a Maslow system but decided to stick with the laser cut. Probably a good choice as FedEx is having a hard time trying to figure out how to deliver my router.
I finished putting together the first piece last night. Now I just need to do all the other cuts.
