3D printing & 3D scanning

Ordering 3D prints | 3D scanning | Creating a model | Pricing | Support structures

The University Library offers a 3D printing service to all LMU members (students, postgraduates, staff) with a valid library card.

We use a Formlabs Form 2 stereolithography printer, for which we accept print orders as .stl or .obj files.

The stereolithography printing process also allows the printing of fine structures; in post-production the objects can be bonded together or lacquered. Currently we offer prints in black resin.

Please note that we are not able to offer post-processing of print models or completed objects.

If you have any questions please contact the University Library 3D team directly:

Ordering 3D prints

Instructions and order form

  1. Please use the order form to upload your 3D model as an .stl file, then fill out the form and complete your order by clicking on the button "kostenpflichtig bestellen" (order subject to charges).
  2. You will receive an e-mail from us with an estimate of the probable cost of your order. The price will depend on the amount of printing materials used.
  3. Please confirm the estimate by e-mail.
  4. You will be informed by e-mail when the object has been printed and is ready for collection.
  5. Please settle outstanding charges via your user account at one of the University Library's pay stations.
  6. As soon as the charges section of your account shows 0 EUR you can collect the printout from the Computer Pool 1 (CIP-Pool 1) in the Main Library.

3D scanning

In addition to 3D printouts the University Library's service also offers you the option of creating a 3D model of an object by scanning. We regret that this service is limited to selected academic projects, as 3D scans involve considerable time and effort.

Creating a model

Free models

You will find numerous websites offering free models, most without restrictions on their use. We have included a selection for you here:

Model size

The printer has a print volume of 145x145x175 mm (WxDxH). In addition, sub-objects can later be bonded together to produce larger objects. The finished objects will be printed complete with bottom plate and support structure.

Colours and materials

Currently we print object in black resin only; we reserve the right to extend or modify our range of resins.

Please note that the resin we use is not of food-safe quality; printouts should therefore not be used with fluids or foodstuffs.

A design guide to successful printing

Observing a few design guidelines when modelling or choosing an object to be printed will ensure good printing results. This applies particularly to the thickness of the walls and the modelling of overhang elements. Please also note that although objects with a hollow design will use significantly less material, the printing technique may lead to the trapping of fluid resin within the cavity. Hollow objects should therefore always include a drainage opening.

Detailed information on the necessary measurements can be found on the formlabs support site.

Pricing

Prices are calculated on the basis of the print volume. For this we use the print software Preform to position the model you submit and to set up the support structures required to ensure a successful printout. Preform then determines the amount of resin required for the job.

A charge of 0.30 euros is made for each millilitre of resin we use. In addition we charge a flat fee of 2 euros; this already includes 5 ml of resin.

Pricing examples by object size: 1.5 cm x 1.5 cm x 2.5 cm, filled: 2 euros; 2 cm x 2 cm x 4 cm, filled: 5.30 euros.

If you wish to check before you order to see whether your model is printable and how much material you can expect to need, you can download the free Preform print software from the developer's website.

Support structures

In order to ensure the printout is stable, a bottom plate and support structures will be added to the print object.

Bottom plate

The bottom plate ensures optimal adhesion to the platform. Without a bottom plate the model would detach or deform during printing. We leave these additional elements in place in order to avoid damaging the model, but they can easily be removed with a cutter or pointed pliers.

Support structures

The support structures are needed in order to fix the object to the bottom plate and support the overhang elements. We make every attempt to place the support structures on the underside of the object, if the model allows it, but regret that this is not always possible. To obtain a smooth surface after removing the struts, it may be necessary to lightly sand the surface.
