Selective Laser Sintering
Technológia SLS (Selective Laser Sintering), kde spekanie prebieha skenovaním laserového lúča danej vrstvy. Po naskenovaní prierezov v jednej vrstve sa tlačová doska posunie o výšku jednej vrstvy nižšie, systém nanesie a utlačí novú vrstvu prášku a celý proces pokračuje a opakuje sa až do poslednej vrstvy.
Štandardná výška vrstvy je od 75 do 175 mikrometrov. Priemer lasera závisí od konkrétneho typu stroja, štandardne od 200 do 700 mikrometrov.
| Parameter | Hodnota | |
|---|---|---|
| Tlačový objem | 130 x 180 x 330 mm | |
| Maximálna veľkosť tlače (diagonálne) | 398 mm | |
| Hrúbka vrstvy | 0,075 mm – 0,175 mm | |
| Rýchlosť tlače | 10 – 14 mm/hod | |
| Priemer laseru | 650 μm | |
| Laser | IR 30 W | |
Multi Jej Fusion
Technológia MJF (Multi Jet Fusion), kde spekanie prebieha pohybom celej tlačovej hlavy v jednom kroku na celú vrstvu. Patentovaný systém od spoločnosti HP nanáša tlačová hlava lokálne na nespečený prášok pojivá (reakčné tekutiny), ktoré sa teplom aktivujú. Po aktivovaní danej vrstvy sa nanesie a utlačí nová vrstvu prášku a celý proces pokračuje a opakuje sa až do poslednej vrstvy.
Štandardná výška vrstvy je 80 mikrometrov. Rozlíšenie závisí od typu stroja, štandardne je 1200 dpi.
| Parameter | Hodnota |
|---|---|
| Tlačový objem | 380 x 284 x 380 mm |
| Presnosť tlače | 0,2 mm a lepšie |
| Hrúbka vrstvy | 80 mikrometrov |
| Minimálna hrúbka steny | 1 mm, pre flexibilné kĺby 0,5 mm |

Materials for Sinterite (SLS)
Nylon PA12 (Polyamide PA12)
A universal thermoplastic suitable for most functional and technical applications. It has balanced mechanical properties, high thermal resistance (up to 175 °C), and chemical resistance. This material, labeled "Industrial," is especially suitable for industrial use due to its high surface quality, precision, and relatively low production cost. Short delivery times for SLS (in some cases even within 24 hours) also make it the most widely used material.
Materials for Multi Jet Fusion (MJF)
Nylon PA12 (Polyamide PA12)
Similar to Nylon PA12 for SLS technology, this material is also universal with comparable properties. The main difference is in the productivity for large batch production, where MJF is more suitable. It is also appropriate for parts exceeding the maximum length dimension of 350 mm.
Nylon PA12 + 40% Glass Particles
Nylon PA12 with up to 40% glass particle content has higher stiffness and thermal resistance than its pure variant. In practice, however, its use is limited due to higher cost and longer delivery times.
Nylon PA11 (Polyamide PA11)
A tougher and more flexible variant of Nylon PA12. However, in practice, it has limited use due to higher cost and longer delivery times.
TPU 95A Rubber
Rubber material with a hardness of 95A. It allows the production of flexible and very tough parts with complex geometry. However, compared to the most common PA12, the price is higher and delivery times are longer.
Manufacturability assessment
Manufacturability assessment and quotation begin upon receiving a 3D model in STEP, STP, STL, OBJ, or 3MF format. If you don’t have your own 3D model, we can help create one based on your specifications by sending us a photo, drawing, or sketch.
