Re: Resin film or residue with the prints

Are you recharging and cleaning the vat window after every print? When I finish a print, I remove the vat and place it on an angled surface so the resin settles below the window and the window is exposed. Before the next print I gently squeegee and wipe the window with a microfiber cloth that is lig...

Re: Surface finish is increasing thickness?

Not yet but spoke with the factory and they said there should be no increase in print thickness in any direction X,Y, or Z. Robert I agree there SHOULD be no increase, but that isn't my experience. For example, 0.5mm diameter prongs were consistently coming out 0.6mm. Shanks were 0.1 mm thicker (wh...

Surface finish is increasing thickness?

Has anyone else noticed that the new surface finish feature is making models 0.1 to 0.2mm thicker than designed? This has become an issue with a wide & heavy ring.

Re: Back of my model

Without a picture to go by I'm just guessing but it sounds like you are growing the model parallel to the build table. Instead, try rotating the model 25 or 30 degrees. The added bonus of printing flat pieces at an angle is you won't need a lot of supports so clean up is easier. Otherwise, you'll ne...

This sounds amazing! Thank you!
I'm wondering if Surface Finish will affect print speed or detail?

Re: Settings

Got the FEP on, trying to get the setting right as my first print layers stuck to the film. EDIT: looks like it ALSO was sticking to build table, and the bits stuck to the film are not in the same space, so it's something else?? A- Safe way to get those off? B- I have been digging and only found the...

Re: Pores in white gold 18k casting (with vacuum) see the images

I agree with Mark.
To be safe, 18k white needs at least 50% fresh metal every melt because the alloys burn away... even more when the metal is overheated.

Re: Print detail suddenly poor (emerald, 30x30y, creator1.2)

Foggy PDMS sounds like the problem. My 1.2 was giving (at most) 15 prints per coating... with the last few prints having degraded quality. I am SOOOOO happy we upgraded to the B9 Core! Never needing to perform calibrations or change pdms is a real game changer. :D

Re: Formlabs Castable Wax Resin Settings on B9 Core

Been casting all the B9 castables since the beginning. I am now casting almost daily using Emerald Green. This may not be for everyone but based on my work and the fact that I use to heat cure prints I have now gone to this burnout. Using nothing but Ultravest Max, a broken arm casting machine, a 8...

Re: The problem of wave

In my experience, if you simply snap the model to the floor, you will likely end up missing part of the base. Since the Core "sinks" the model approx 0.5mm below the floor, I will either (1) put the model on a foundation disk and remove the disk after curing, or (2) extend the model base a...

issue opening core projects in Win7

Since the last update (54), I am unable to open an existing core project (.cpj) by double-clicking it (in Windows 7). Double-clicking only opens the Create program. Then I have to open Editor, click Open and navigate to the project file. Is anyone else running Win7 having this issue? BTW, double-cli...

Re: Long Time Lurker With A Print Issue

I don't believe anodizing makes any difference in the performance of the table. What IS important is the platform needs to be flat and perfectly parallel to the pdms. When calibrating, if the table lifts up at even one corner during tightening, you'll have problems. If the pdms isn't perfectly level...

Re: Yellow is not mellow

To cover all the bases here.... After envesting, are the flasks being allowed to set undisturbed a minimum of two hours before burnout? We let ours sit for 3 hours just to be safe.
