Do you need a spare part or want to have a model of your game character? Do you need a cool gift or want to have the results of your thesis on more than just paper? Then you are at the right place!
Since 2015 we are offering a 3D printing with our two Ultimaker 2s and a Formlabs Form 2.
We offer our 3D printing services to students, staff, and external customers.
Since we are currently restructuring, the ordering process is currently by mail.
- Upload model as stl file named sensibly at https://nextcloud.in.tum.de/index.php/s/xcoYY4Pzg3LKpHy.
Mail to email@example.com with subject [order] and specification for each part:
- Filename, size, quantity, material, color.
Please also include your name and whether you are a student, employee or external.
- We will get back to you with any questions
- We will send you an email as soon as your item is printed.
- Pick up and pay cash at the script sale.
What sizes are available?
We can print objects in one piece if they do not exceed the following dimensions:
Ultimaker: BxTxH: ~190 x ~190 x 205 mm
Formlabs: BxTxH: 145 x 145 x 175 mm
Of course, you can also assemble your object parts afterwards to get larger objects.
The price is made up of a flat rate and cost per gram:
|Status||Flat rate||Cost per gram|
|Students||3.00 €||0.074 €||0.23 €||0.32 €|
|Staff||6.00 €||0.097 €||0.42 €||0.63 €|
|External||9.00 €||0.117 €||/||/|
They are gross prices and rounded. If the same object is to be printed several times, the flat rate fee is charged only once. For students, we can charge with 7% VAT, for employees and external clients we have to charge 19% VAT.
Materials and Colors
We can print the following types of synthetic materials for you:
- PLA: for ordinary objects, such as figurines (Colors: Black, White, Grey, Green, Pink, Iceblue, Pearlwhite, Gold)
- Formlabs Resin: for durable objects such as gears and very fine structures.
- Formlabs Standard Resin: For parts that require high resolution or hardness of the material, for example objects with very fine structures or parts where smooth surfaces are required. The parts from Formlabs have a resolution close to that of injection moulding. Formlabs standard resin is very hard and therefore brittle. Thin parts splinter under load. For heavy-duty parts we recommend Formlabs durable resin, which is slightly flexible and can withstand higher loads. (Colors: Transparent, Clear)
- Formlabs Durable Resin: This resin is less hard than the standard resin. Its properties are comparable to polypropylene. This material is suitable for parts that are exposed to mechanical stress, such as gears or joints.
The currently available color selection is presented as part of the order process.
Critical Points / What Should I Look Out For?
Since the Ultimaker builds the object in layers from the bottom up, overhangs from 45 ° pose a possible weakness in terms of print quality. Particularly 90 ° overhangs and floating structures are problematic. These are usually supplemented by us with support structures, which you then have to remove afterwards. We have files and knifes for this purpose.
What material should I use? I just want something to look at and show. I otherwise have no special requirements.
When in doubt, always use PLA first. This is the easiest for us to print and you have the largest selection of colors. Without special requirements, PLA is the right choice in about 95% of cases. If you have a very delicate part or a part that needs high precision on edges and planes, you probably want to print on the formlabs. The formlabs offers very sharp edges and flat planes.
How much will that cost?
We do not provide any estimates since that is quite difficult. We may otherwise give a wrong estimate.
Not even a rough estimate?
The software that we use (Cura), calculates estimated material consumption. If you view your model in Cura, you can perhaps get a rough estimate.
However, since we use our own profiles, the actual material consumption may differ from your calculated consumption.
There are odd edges on the base and stuff was printed that was not in my model!
That may occur. These odd edges at the base are the brim. It gets printed to get a better grip on the printing surface. Without it, the model could shift or slip during the printing process due to pressure.
The brim can be removed relatively easily with a utility knife and needle nose pliers. If the printed object contains other things, which were not part of the model, these are most likely support structures which are automatically generated and inserted by Cura. These can usually be easily removed and have a support function only during printing.
Can you handle the post-print processing (removing of brim and support structures, etc.) for me?
No, unfortunately not. Customers should handle this to their own specifications, so that we don’t inadvertently destroy or damage the object.
I would like to print a model, but it does not yet fit right. Can you fix that for me before printing?
No, for the same reason as above. We do not know what you would want exactly. Since we are students and do 3D printing in our spare time we also do not have the time.
Can you at least look at my model and let me know if you can print it?
No problem, simply write us an email at firstname.lastname@example.org!
I have another question.
Then just write to the person responsible for 3D printing from the printing unit at email@example.com.
