CLAIMS:
1. A method for manufacturing a 3D article (1) by means of 3D printing, said method comprising the steps of: a) printing a 3D structure (G) comprising a first surface (4) and a second surface (4’) being opposite to said first surface (4), the 3D structure (G) comprising a portion (3) extending from one of the first surface (4) and the second surface (4’) in a first plane; b) cooling said 3D structure (G); c) heating said one of said first and said second surfaces (4, 4’) of said 3D structure; d) deforming said 3D structure (G), by means of bending the portion (3) in a second plane deviating from said first plane, such that the 3D article (1) is obtained; e) cooling said 3D article (1), wherein the method further comprises the step of: a’) printing at least one bending tool for defining an angle of bending.
2. The method according to claim 1, wherein said printing in step a) is performed by fused deposition modelling (FDM).
3. The method according to claim 1 or 2, wherein step c) is performed by arranging said one of said first and said second surfaces (4, 4’) of said 3D structure on a heating plate.
4. The method according to any one of the preceding claims, wherein step c) is performed at a temperature from 120°C to 180°C.
5. The method according to any one of the preceding claims, wherein said method further comprises step d’) of stretching said 3D structure, wherein step d’) occurs between step c) and step e).
6. The method according to any one of the preceding claims, wherein step a’) occurs simultaneously with or immediately after step a).
7. A 3D article (1) manufactured by the method according to any one of claims 1-6, wherein said 3D article comprises a first portion (2) extending in a first plane and at least one second portion (3) substantially extending in a second plane deviating from said first plane.
8. The 3D article (1) according to claim 7, wherein said second portion (3) of said 3D article comprises at least one aperture (5).
9. The 3D article (1) according to claim 7 or 8, wherein said second portion (3) of said 3D article is discontinuous.
10. The 3D article (1) according to any one of claims 7-9, wherein said second portion (3) of said 3D article is constituted by at least one snap-fit locking device.
11. The 3D article (101) according to any one of claims 7-9, wherein said 3D article (101) is substantially dome-shaped.
12. The 3D article (1) according to any one of claims 7-11, wherein said 3D article (1) comprises a UV stabilizer arranged to inhibit photodegradation.
13. The 3D article (1) according to any one of claims 7-12, wherein said 3D article (1) comprises thermoplastic biopolymer.
14. The 3D article (1) according to any one of claims 7-13, wherein said 3D article (1) has a thickness of from 0.5 to 5 mm.
15. The 3D article (1) according to any one of claims 7-14, wherein said 3D article (1) comprises a reinforcing additive arranged to increase the impact strength of said 3D article (1).
