plywood bed I think someone already try this. However I'd like to post my experience. After trying different solution for the bed I try to print directly on plywood with very good results: good adesion and easy to remove with a sharp knife. Looking at the results I ask myself why this solution is not in the list of reprap possible bed. I'm using a 12 mm multi-layer that is manufactured with very good surface finish. Forthermore is a very cheap material. https://reprap.org/forum/read.php?1,390748,390748#msg-390748 Sat, 17 Oct 2026 02:36:36 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,390748,396316#msg-396316 Re: plywood bed https://reprap.org/forum/read.php?1,390748,396316#msg-396316

glass is ideal because it is rolled flat.
Modern sheet glass isn't rolled. It's floated on a bed of molten metal, typically tin. That's what gives it it's uniform length and makes it so flat.]]> cdru General Mon, 18 Aug 2014 09:08:09 -0400 https://reprap.org/forum/read.php?1,390748,396267#msg-396267 Re: plywood bed https://reprap.org/forum/read.php?1,390748,396267#msg-396267

A piece of acrylic sized to the bed is going to be quite cheap also.]]> tjb1 General Mon, 18 Aug 2014 07:26:46 -0400 https://reprap.org/forum/read.php?1,390748,395375#msg-395375 Re: plywood bed https://reprap.org/forum/read.php?1,390748,395375#msg-395375
but what is most common is to use wood and blue tape. glass is ideal because it is rolled flat.]]> jamesdanielv General Fri, 15 Aug 2014 20:47:35 -0400 https://reprap.org/forum/read.php?1,390748,395175#msg-395175 Re: plywood bed https://reprap.org/forum/read.php?1,390748,395175#msg-395175 tjb1 General Fri, 15 Aug 2014 08:53:24 -0400 https://reprap.org/forum/read.php?1,390748,395031#msg-395031 Re: plywood bed https://reprap.org/forum/read.php?1,390748,395031#msg-395031

I'm not here to propose this as the perfect bed material, I want only propose it as an other possibility.

Thanks a lot for posting your experience, I have been wondering for a while about this solution and now I know that it may work.]]> cristian General Thu, 14 Aug 2014 21:43:09 -0400 https://reprap.org/forum/read.php?1,390748,391069#msg-391069 Re: plywood bed https://reprap.org/forum/read.php?1,390748,391069#msg-391069

So I presume that since you tried it out and it worked for you that you added it to the list? No? Well why not? There's your answer.

My guess is that it's not on the list as the results are not highly repeatable. Every time you scrape off a print you're going to be changing the surface, much more so then a metal, acrylic, or glass bed. Other issues are easily gouged, inability to use a heated bed, surface finish, tearing off wood fibers, weight, flatness, dimensional stabality...The only thing it has going for it is that it's cheap.

I've used it quite a lot and I don't see these problem so relevant, if you stay light scraping you have a good lifetime.
I don't use a heated bed thanks to the good adesion, I have a very good finish with no fiber tearing off (maybe thanks to the good material quality), the weight is not so high ans during the production is calibrated to be very flat (mine has no significant bending). The downside is moisture naturally absorbed by wood, that can change lightly the dimension (I have not seen this yet).
For the cheap fact, this may be important for some people, as a matter of fact I try to buil my own printer cheapest as possible: I've built a pretty good printer with less then 250 € (335 $).
