Guides
Practical guidance from model to finished part: choose a material, prepare your file, recreate a replacement part and understand how pricing works.
Recreating a replacement part without a 3D model
No 3D model of the broken part? Learn which photos, measurements and details we need to recreate it for 3D printing.
Which material for which use: PLA Basic, PLA Matt, PLA CF and PETG
PLA or PETG, matte or carbon-fibre reinforced? A clear comparison of Printimir's four printing materials and their uses.
How to prepare an STL file for 3D printing
Closed geometry, correct units and suitable wall thickness: how to prepare a printable STL file and avoid common problems.
What 3D printing costs and why
Why there is no fixed price per part, how material, print time and quantity determine the price, and how to reduce it.
When 3D printing is the right process, and when it is not
FDM 3D printing has clear strengths and limitations. An honest guide to whether it suits your part.
Parts over 256 mm: scaling, splitting and bonding
The build volume ends at 256 mm per edge. Learn how larger models can be split, printed and joined effectively.
3D printing for prototypes: test form, fit and function
Use printed prototypes to answer the right questions early and compare design variants clearly.
3D printing file formats compared: STL, OBJ, 3MF and STEP
Which 3D file format to upload and what STL, OBJ, 3MF and STEP mean for colour, scale and accuracy.
