FDM often costs less for both equipment and materials. Additionally, larger parts may be produced with superior mechanical performance than with SLA. SLA, on the other hand, offers far finer details and better surface quality.
An SLA specifies the kind of service you can anticipate and enables you to hold your service provider accountable. You can lessen some of the effects if the needs that were agreed upon are not covered by requiring your provider to make up the losses. SLAs are preferred by service providers as they significantly increase client retention.
As a general rule, this results in DLP 3D printers being faster to print huge, completely dense prints or constructions with several components that occupy up much of the platform, while SLA 3D printers are faster to create tiny or medium-sized single parts.
The number of calls answered within the service level threshold divided by the number of calls offered, multiplied by 100, is the service level formula.
The SLA should outline the expected service levels and the services that will be rendered, as well as the metrics that will be used to monitor those levels, the roles and obligations of each party, remedies for breaches, and a procedure for adding and removing metrics.
A penalty or credit may be applied when a SLA obligation is broken in order to make up for the breach. For instance, if a customer asks you to repair a part of an asset, the customer is required to send the broken part to a specified location within three days.
Thermoplastics include both PLA and ABS. Although PLA is stiffer and tougher than ABS, it has low heat resistance, making it mostly a hobbyist material. ABS is a better plastic for prototype applications since it is less stiff and weaker but also harder and lighter.
If you make sure that the temperature in your workspace is constant at 75°F (24°C) and doesn't drop below about the 68°F (20°C) threshold, the resin won't completely harden if the temperature drops too low. 64–82°F (18–28°C) is the operating range for Formlabs resin 3D printers.
A tiny model can be printed in as little as 15 minutes, but a huge house model can take several days. 2. The layer thickness for an industrial SLA 3D printer might be anything between 0.05mm and 0.2mm. In actuality, layer thickness between 0.05mm and 0.1mm is most frequently employed to provide superior surface quality.
Older epoxy resins were found to cause skin cancer in tests on lab animals. The most likely culprit is epichlorohydrin, which also most likely contributes to human cancer. However, more recent epoxy resins don't induce cancer in animals since they have less epichlorohydrin in them.
