Hi, for this model, you really dont want to pull it off of the build plate by the tulle. You need to go kind of slow and use a scraper, so the tulle doesn't rip. It can be tedious but it is worth it.
Hello Forge Core Support Team,
I am currently trying to print an umbrella model from the Forge Core subscription using my Bambu Lab A1 mini, but I’m facing repeated print failures and would appreciate your guidance.
Problem Description
During printing, I am experiencing the following issues:
- Warping and edge lifting on multiple umbrella segments
- Infill deformation and tearing, especially in curved sections
- Poor layer adhesion where red and white sections meet
- The model appears to lose structural integrity mid-print, causing - -uneven surfaces and broken geometry
I’ve attached an image showing the failed print for reference.
Printer & Material Details
Printer: Bambu Lab A1 mini
Filament: PLA (brand tested multiple times)
Nozzle: 0.4 mm
Build plate: Textured PEI (cleaned before print)
AMS: Not used
Slicer: Bambu Studio (latest version)
What I’ve Already Tried
Re-leveling the bed
Cleaning the build plate with IPA
Adjusting bed temperature
Slowing print speed
Reprinting individual segments
Using default Forge Core profile (if provided)
Despite this, the same failure pattern occurs.
The Fabric is needed for the umbrella. It is what holds the printed pieces together. If you try to print it without the tulle all of the diamonds and umbrella bars will not be connected to each other.
ok i went and got some how do i print with it? videos I've watched say to print 2 layers then put the fabric down and print the rest on top is that what you do with the umbrella too?
I'm not sure what rectangles you are referring to. unless you mean the design I have in there to make it look like the wood boards of a regular picnic table.
We design all of our models with PLA in mind so if you want to switch to PETG you do have to make sure you have your setting as dialed in as possible to get the same results.
Hi! I'm sorryyou're having trouble. You may need to refine your bridge settings or check for over-extrusion if the legs print fised or stuck. sometimes a nozzle can be worn out and cause the over-extrusion and somethimes it is filament settings. I can't be sure which would be causing your issue.
where are there clear instructions? which way does the umbrella fold its very hard to bend the pieces without breaking. there are not any tabs on the cap for the top? do you cut out the fabric in the middle? how does the rubber band go underneath? the pictures are not that clear to understand. and your video isn't showing you put the umbrella together. I really do not want to break another umbrella - thx
Hi, you will want to cut out the holes in the top of the umbrella so the arms can move freely. The rubberband goes through the umbrella cap under the conector tab, and into 2 of the umbrella holes and then around 2 of the black arms. There are better pictures in the Helpful instructions project page.
The black arms are only meant to be snapped into the holes of the underside of the umbrella. It is not meant to be touching the umbrella fully or to keep the umbrella open completely flat. It stays at a slight angle like a true umbrella. There should be a gap between the umbrella and the pull down part of the umbrella, like in the photos. The rubber band is there to help it stay open. so you shouldn't have to insert it upsidedown.
i printed the table and it was fused (i half blame my printer) i had to use my printer that it fits on and it was completely fused. i have another printer that is more accurate i will try (also with some supports. the problem is it doesn't fit so im gonna cut the legs shorter (its too big by like 2mm each side). any tips on having the table actualy work
If the table is fusing together it is likely due to the bridge settings or it can be a printer error. if your using a bambu printer with the 3mf then I would think it would be a nozzle issue ands likely the nozzle needs replacing. If you're using a different printer and your own settings, I would run some bridge tests to see if your printer is bridging properly
Hi! Can you please tell me where the umbrella file is and what the tulle and bar magnets are for. All there is is the picnic table with rubber band. Thank you! I am guessing those other items are for the umbrella...
Hi, The umbrella is in the 3mf when you download it, If you don't see it you may need to re-download it. The tulle and magnet bars are for printing the umbrella. The instructions are in the description under "Helpful Instructions" If you click that it will take you straight to the instructions for printing and assembly.
I will try the download again. and yes, as soon as I saw the new link for helpful instructions I saw the tulle and magnet. Thank you for your response!!

do you have to have that fabric stuff to print the umbrella? you cant just print it up?
The Fabric is needed for the umbrella. It is what holds the printed pieces together. If you try to print it without the tulle all of the diamonds and umbrella bars will not be connected to each other.
nevermind i see your instructions now so sorry
ok i went and got some how do i print with it? videos I've watched say to print 2 layers then put the fabric down and print the rest on top is that what you do with the umbrella too?
Você apenas disponibiliza o arquivo em 3mf? Eu quero o stl para pode adequar as minhas configurações.
We only provide the 3mf. It should open in most slicers and you can change the settings to your preference.
Porquê quando abro o arquivo, na mesa tem alguns retângulos?
Tentei reproduzir e a mesa não abriu, imprimi em petg, provavelmente por isso. Vou tentar em PLA desta vez

Infelizmente estou tendo problemas ao imprimir o modelo. As pernas da mesa sempre colam, e fica com dificuldade na hora de abrir e fechar .

hoe hard d you have to push the arms into the hole?

Yes but the pull down part of the handle is not correct. I have to insert it upside down and then the pull down handle part is wrong.

I'm having the same problem. I printed the table and the legs were fused together, and when I try to release them, the sides of the legs come apart.
If the table is fusing together it is likely due to the bridge settings or it can be a printer error. if your using a bambu printer with the 3mf then I would think it would be a nozzle issue ands likely the nozzle needs replacing. If you're using a different printer and your own settings, I would run some bridge tests to see if your printer is bridging properly
... i didnt have my bridge setting on... Cura be stupid
I would suggest trying Bambu Studio. It is very user friendly and supports more than just Bambu Printers
i would have printed it on my anycubic kobra 3 but its slightly too big
well I wasn't using the best printer to be honest. it was an old artillery x1 but I can run a bridging test on it.
Whe removing the umbrella its coming off in little triangle why?
Can you give me a little more information on what is happening? Is the tulle ripping or something else?
Where is the umbrellas for the set? thank you
Hi, It is in the 3mf when you download the file. if you don't see it in yours, try re-downloading it.

Yay! I got it. I had to redownload it. Must of been before you made any changes. Thanks again!
