Winterproofing my 3D printer - part 2

Well it seems the reptile heating mat worked. I left the printer running over night. The weather got particularly frosty that day but the print did not suffer from the resin curing problem again.

 

The print did fail but the cause was the print sticking to a damaged part of the FEP film. When I tried to scrape it off the film actually tore open. It wasn’t until this weekend that I had the time to replace the film and get the printer up an running again.

Layer separation problem - was the resin too cold?Layer separation problem - was the resin too cold?

I’ve been running my 3D printer for several months pretty much constantly and had got to the point where I felt confident getting reliable prints, or at least fixing and avoiding the common problems.

 

I was starting to print terrain to go with my Dweghom force, so I was repeating the same prints over and over, when suddenly they all started to fail like in the picture above. A layer fails to adhere to the model and instead sticks to the FEP. Eventually it starts sticking to the print again, but you end up with these large gaps.

 

I had actually seen this before when I first changed resin from the one supplied by the manufacturer with the printer, to Elegoo resin from Amazon. I solved that by increasing the cure time slightly.

 

The sudden failure to print corresponded to winter kicking in here in the UK and the temperature dropping. My printer is in an unheated garage and so is susceptible to changes in temperature.

 

A quick google search confirmed that this can be a problem. Cold resin not only cures slower but will also not flow as well in the resin vat.

My solution was to buy a 20W reptile heating mat from Amazon (https://www.amazon.co.uk/gp/product/B08FXBT67D/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1). I had a pack of foam floor mats left over from when I put them down on my garage floor. I assembled these into a cube, placed the heater underneath the printer and then sealed it up. I also have a thermometer on the way to put in there, but it hasn’t arrived yet.

 

Total expenditure so far is £29.43.

 

I’ve got it warming up right now and will start printing the tree again later today.

 

Let’s see how it turns out.
