The problems I have been having is that the recommmended exposure time never worked to create attachment. I will try lowering the layers exposure to get that detail back.The reason I upped the exposure...

Hoping someone can verify that my thought process here is correct. I’m having a lot of problems with print jobs sticking to the base plate – but the first layer(s) *DO* stick to it. So when I go look,...

So I tried anothe print today. Had the same problem as before with the print not detaching from the vat. It seems to be happening around halfwya into the print just due to the width of the part I...

At higher resolutions, small changes in exposure matter more because the light intensity is significantly higher. Other than that, I don’t know whether you would find any differences in adhesion when...

In general when printing objects, you want to orient them in a way such that surface area reduces, rather than increases, over the duration of the print.The earlier layers need to survive many more...

There are reports of various oleophobic coatings being used on glass and other substrates on buildyourownsla.com, none of which worked well because they were not any less adhesive than FEP (teflon)...

Your pictures are a bit small, but if you have an XY plane issue, you should probably go back and make sure that your projector is level to the extent that the calibration grid lines up squarely with...

Thanks James,I actually followed your video to setup the Z-home. The attachment layer was about 0.5mm thick and this may be the reason. I found that if I used the raft provided by CW, that results in...
View ArticleReply To: Advice for printing needed
If you use the attachment generated by CW, you should scale it down to be 1 layer thick. So if I’m using 100 micron Z, then I’ll scale that object down to 10% along the Z axis to make sure that it’s 1...

Dear James,Thanks so much for your tips! I eventually gave up on Maker juice and used 3DS-ABS like material. Much better and I can finally get decent printout!

Alright so I think I got the base plate z-0 calibrated correctly this time and you’re right I’ve noticed huge improvements as far as attachment goes.Now that that seems solved I just need to figure out...

Whether you need more or less exposure will depend on the shape of the feature.If the feature is a positive feature, like a thin wall or prong that sticks out, then you may need more exposure to ensure...

I guess that means I need to buy some pigment. I’m currently just using the regular 3DM cast resin. I’ve attached a picture of what is giving me the most trouble to come out. Fortunately there’s only...

Hmm… I’m typically very positive about the printability of large objects on the Titan 1, but I have a feeling that you may not be able to print this at both the size and the detail that you want,...

Assuming those red dots are on top of the piece of teflon plastic, then I would assume that it is projecting dots (white spots) on some of the later layers. Due to the space between the build plate and...
