The following texts present you the manufacturers Ultimaker & Formlabs to give you a short overview of the manufacturers and their methods of manufacturing.
Ultimaker is an netherlandisch manufacturer producing 3D Printer since 2013 using the FDM/FFF method. Fused Depositing Modeling means, that the plastic, wich is also called filament , is transported to the printhead and gets extruded by a 190 - 280°C nozzle. The fuzed plastic gets apllied layer per layer by the printer wich makes use of his three degrees of freedom.
Following some technical data:
- Printing volume: 10 195 - 23 760cm³
- Layer hight: 0,03mm - 0,25mm
- connectivity: WLAN & LAN (only available for UM3 & S5)
- User interface: LCD/Touch or Remote Control
Furthermore the Ultmiaker 3D Printer can use a wide variety of plastic with different characterstics.
- PLA (small warping & easy to manufacture)
- ABS (high warping & resistance)
- Nylon (needs special storage conditions but has a very high resistance)
- Polycarbonat (extrem resistance)
- PET (foo-safe)
- PETG (High shore hardness)
- TPU (Flexible)
- PMMA (dimensionally stable up to 90°C)
- ASA (resistant to chemicals)
- PVA (Water-soluble)
The american manufacturer Formlabs uses an different method of additive manufacturing. The Formlabs Form 2 is based on the SLA technology (stereolithography) wich means, that the photopolymer (Resin) get hardened by a laser. This technology is very widespreaded and finds an productive usage in diverse segments. This method of manufacturing allows a very precise and fitting printing method with a tolarance below 0,1mm and can therefore even be used to print objects that are used by a dentist. Due to the wide spectrum of application possibiltys the manufacturer also produced printingmateriel with a variety of characteristics such as:
After printing there is a material specific hardening- and cleaningprocess that must be followed. This process however gets a basic routine after a while of printing..
- Formlabs Wash
- Formlabs Cure
Following there is some technical data regarding the Form 2 SLA 3D pinter
- Printing volume: 145 x 145 x 175mm
- Laser diameter: 0,14mm
- layer hight: 0,025 - 0,1mm
Characteristic features of the additive manufactering
The is a variety of benefits to 3D printing compared with more traditional manufacturing methods. In the following there are some of them listed and explained.
sparing with ressources
The outcome material is dependent on the choosen way of manufacturing either in form of an plastic rope (Filament/FDM), a resin (Photopolymer/SLA) or is pulverized (SLS).
Each of the mentioned methods of manufacturing and their outcome materials have their specific characteristics aswell as individuall beneftis and drawbacks. But all of them have one in common and that is that there is no clipping meaning that there is basically no waste of material. Based on the method, the plastic gets either melted or hardened by a laser but every method only uses as much of the material as needed and nothing more. This means, that the material can be used completely without wasting a part of it.
Modelling and printing of complex structures
The similitude of substractive manufacturing is milling. Eventough that those machines also called cnc milling machines are computer based and work almost fully automized there are physical limitations to this machines espacially concerning cavities or filigree structures. The additive manufacturing however has no such physical limitations meaning creating cavities or printing very filigree structures can be done without any problem. This means that the additive manufacturing method has the edge over substractive manufacturing espacially regarding the mentioned field of applications.
Low changeover costs
Beside the high working costs as electricity, maintenance and the costs of attrition that a CNC milling machine brings with it there are also the chanceover costs that should not be underestimated. The whole milling process has to be programmed with the help of an CAD programm that has its costs and also takes some time everytime a new object has to be milled or if an already milled objects has to be modified. The printers that are used for additive manufacturing however each come with a software that automatically take over the tasks that have to be programmed manually when milling. This results in an reduction of an 5 hour amount of work into a 5 minute amount of work reducing the costs of this by a lot.
Field of applications
There is a wide spectrum of applications for additive manufacturing such es design objects but also highpressure mechanical components to only mention some of them. This means, that 3D printing can not only be used for filigree objects but also for objetcs that need a high resilience.
