Technologies numériques/Textiles/Impression 3D sur tissu

Avant-Propos

L’impression 3D est si polyvalente qu’elle peut également être incorporée au tissu, créant ainsi des caractéristiques futuristes.

Il a prospéré dans l’industrie de la mode et de nombreuses marques célèbres fabriquent et vendent actuellement des vêtements imprimés en 3D.

L'impression 3D vous permet de créer vos propres motifs pour vos vêtements et de les personnaliser à votre guise.

Divers applications de l'impression 3D sur tissu sont notamment les déguisements des cosplayers, des chaussures, des bijoux et vous pouvez même raviver vos anciens chandails en ajoutant des beaux motifs d'mpression 3D qui peut certainement peut donner vie à vos créations.

Figure 1. Impression 3D sur tissu

Cet article vous donnera un aperçu sur les étapes à suivre pour faire une impression 3D sur tissu .

Trois exemples sont couverts, cependant la technique demeure la même.

Exemples d'impression 3D sur tissu

Les figures suivantes démontrent les résultats.

Écailles de dragon

Les écailles de dragon sont inévitable quand on confectionne les déguisements de cosplayers.

De plus, leur allure féerique serait plaisant aux fans de la fantaisie.

Comme démontrée dans la photo, vous pouvez créer vos propres tissus avec des écailles de dragon en incorporant votre tissu entre les deux parties imprimées.

Les hexagones qui brillent dans le noir

Les hexagones font une belle motif qui pourrait être idéales pour confectionner des bijoux.

Les boutons-pression photochromatiques

Les boutons-pression pourrait révolutionner la manière dont on utilise les boutons qui sont généralement cousus sur vos chemises.

Une variété de filament a été utilisée pour ce projet. Vous pouvez utiliser le matériel de votre choix et faire les changements nécéssaires dans votre découpeuse.

Les filaments utilisés

Le tableau suivant démontre les imprimantes qui étaient utilisés avec les différents types de filaments et aussi les difficultés qui ont surgit durant l'impression.T

L'imprimante, Flsun v400 était le premier choix pour imprimer les trois exemples car elle est plus rapide et convient idéalement au filaments qui font 1,75 mm d'épaisseur , malheureusemnt, un des filaments, le 'Woodfill PLA' n'a pas bien fonctionné avec cette imprimante.,

Printer	Filament	Slicer	Difficulties encountered
Colour fab Wood fill PLA (2.85 mm)	Ultimaker 2+-Nozzle 0.4 mm	Cura	Incessant clogging with Flsun v400 printer Got burnt several times v400 nozzle Over extrusion with a 0.8 mm nozzle-UMP Was not adhering to build plate-UMP
Glow in the dark PLA (1.75 mm)	Flsun v400	Cura	No significant difficulties were encountered, it worked like normal PLA
Photochromatic PLA (1.75 mm)	Flsun v400	Cura	No significant difficulties were encountered, it worked like normal PLA

Note: Some specialty filaments are abrasive and can severely damage the nozzle

Getting Started

Preparing your model

A 3D CAD software, such as Onshape can be used to build up your model from scratch.

Or you can find some readily available designs online on Thingiverse.

Note: The dragon scales and the hexagons were from Thingiverse.

-Dragon scales

-Hexagons

-Snap buttons

Slicer

Now you must bring your model to your slicer.

To use the slicer:

• Download the slicer you will need for free or use one of Makerspace's computers. In our example we will be using Ultimaker Cura.
• Bring your model to your slicer. Remember to save your file as STL.

Print settings

The following table shows the changes made in the print settings; all other settings were left the same.

	Dragon scales	Hexagons	Snap buttons

Nozzle size	0.4 mm	0.4 mm	0.4 mm

Printing temperature	_	210 °C	210 °C

Table 2. Filament used

Additionally, to facilitate the printing process after incorporating the fabric,

Go to Custom --> All in the Print settings and enable the following:

• Enable Retraction-reduces stringing,
• Z Hop when retracted-prevents nozzle from dragging along surface,

Fig 7. All print settings

Note: For the Ultimaker printer, you may have to clean the build plate and adjust its level if your filament is not adhering to it.

• To clean: Use the cleaner available and paper towels and carefully wipe the build plate.
• To adjust level: At the Ultimaker printer go to Maintenance -> Build plate and follow the instructions given.

Calibrating the build-plate:

Calibrating the plate may be necessary when dealing with specialty filament, more information can be found on the following link.

Gathering materials

Before starting your print, ensure that you have the following materials:

• Fabric
• Tape
• Scissors
• Ruler

After gathering your materials,

• Measure out the amount of fabric you would need and cut it out.

Note: Your fabric should be smaller than the print area.

• The fabrics used were tulle and a woven fabric.

Starting your print

Note that the printing will be in two stages.

The first stage will be before the fabric is embedded in the 3D printed part and the second stage will be after its incorporation.

• Save your model and bring it to the printer.
• Switch on the printer and do the necessary configuration depending on the material you are using.
• Begin print.

Let it print the first two layers of your model as shown below:

Figure 8. First stage print

• Pause your print

Incorporating your fabric

• Place your fabric on the part that has been printed.

Figure 9. Taped fabric

• Resume print and watch your 3D printing fabric being formed.

Note: Tulle is a mesh fabric, the first 3D printed part can adhere to the second 3D printed part between the little holes in the fabric, causing the latter to be securely held.

On the other hand, holes need to be made for other fabric types such as woven fabrics to enable the fabric to be stuck between the 3D printed parts.

Perforating woven fabric

The following steps demonstrate how and what kind of holes should be made in your fabric:

• Measure the amount of fabric you would need
• We will use the laser cutter to cut out the fabric, you can use Inkscape to make the perforations.

Figure 10. Perforations Inkscape design

Note: This design was used to maximize cohesion.

• Iron your fabric and lay it on a piece of MDF. Tape it securely into place.

Figure 11. Fabric on board in laser cutter

• Configure the properties as follows:

Note: Laser Cutter used: Epilog Mini

The properties depend on the fabric used:

Vector Settings:

• Speed: 100 %
• Power: 10 %
• Frequency: 150 Hz

• Begin cut:

Figure 12.Perforated fabric

The different configurations will vary depending on the printer, the material or the type of fabric you are using for your project.

Yet, the overall process for 3D printing on fabric remains similar, that is, you should incorporate your fabric in between the two stages of printing.
