What is 3D Printing?
3D printing is also called additive manufacturing and allows you to create three-dimensional objects from a digital 3D model. The 3D model is created with specific software and processed by a 3D printer that, layer after layer, produces the solid part of the 3d model.
What are the main differences between SLA and DLP technology?
On personal/desktop 3d printers there are no particular differences in terms of quality and resolution between SLA (streolithography with UV laser) or DLP (with DLP projector).
What is the difference between top down and bottom up projection?
In the Top down projection technology the amount of resin used is equal to the height of the object, the object is formed without particular types of stress because it simply grows on a moving tray. No change of resin vat is required. After the use the vat is simply closed and can be safely stored. In the Bottom up projection technology the amount of resin used is less, however, the object undergoes more stress due to the suction effect happening at each layer. You must also make a periodic change of the resin vat or the fep film with additional costs.
What kind of software can I use to create 3D CAD models?
There are many professional options you can choose such as Solidworks, Inventor, Rhinoceros. There are also some free software like SketchUp or Blender. Always export the file in .stl before going to printing.
We also organize training courses on different 3D modelling software at our headquarters in Montebelluna (TV).

Which software do I need to operate a Lumi Industries' 3D printer and how much does it cost?
You can download free software Lumi Creator for your model from download area.
What is the main difference between resin based and filament 3D printing?
The main difference between the two technologies is the accuracy and precision of details that you cannot get with filament 3d printing and can be reached only with stereolithography.
What technology does Lumi Industries use?
Lumi Industries’ printers are based on DLP stereolithography technology (using a DLP projector) with top-down projection. A liquid resin cures with the light emitted by a projector.
Where to find models for 3D printing?
On the internet there are many websites colecting suitable models for 3D printing, with a pay or free download. Find here a list of the most important ones.
Which resins does it use and which properties do they have?
There are different types of resins with different properties. Lumi Industries has his own line of resin, optimized for use on their own printers:
- LumiReact Hard & Deatiled: suitable for prints requiring an extreme precision and detail. Perfect for silicon moulding.
- Lumi React Hard & Strong is suitable for parts requiring a certain hardness and for silicone moulding. These resins allow enhancing details accuracy. Available in grey, blue teal or orange
- Lumi React Castable is a metal casting resin. Available in orange
Lumi Industries is also the official distributor for Italy of Fun To Do resins available in the following versions: Standard (35 shore D), Industrial (75 shore D), Snow white, Castable (73 shore D) e Deep Black
- LumiReact Hard & Deatiled: adatta a stampe che necessitano un'estrema precisione e dettaglio. Ottima per gommature in silicone.
- LumiReact Hard & Strong è adatta per articoli che richiedono una certa durezza. Queste resine consentono di migliorare l’accuratezza dei dettagli, ottime per gommature. Disponibile nei colori grigio, blu ottanio o arancione.
- LumiReact Castable disponibile nel colore arancione.
Lumi Industries è inoltre distributore ufficiale per l’Italia delle resine Fun To Do disponibili nelle versioni: Standard (35 shore D), Industrial (75 shore D), Snow White, Castable (73 shore D) e Deep Black.
What is the resin shelf life and how can I store it?
Resin has a shelf life of 12 month from purchase. Once you open it, it has a minimum life of six months.
Store it well covered, in a dry place without temperature fluctuations and away from light sources.
It is important to stir very well the resin before every use to avoid pigments deposition.
Can resin be burn for lost-wax casting?
Yes, the resin casting is similar of the lost wax process, considering that the resin does not melt, but burns, therefore the foundry must take appropriate precautions.
How many parts can I print with 1 liter of resin?
It depends on printed objects volume. Our resins have a tiny shrinkage factor of 0.5%, therefore the printed object volume approximately corresponds to the volume of used resin. After loading the .stl file to be printed on our software and setting the resin in use, it is possible to know in advance the volume of resin used and the corresponding cost in terms of material.
Can I use thrid party resins?
Lumi React resins have been conceived to be used on our printers and give the best results; however, Lumi Industries’ printers are compatible with most of DLP resins.
Are resins recyclable?
No, all photosensitive resins are made on an acrylic base and are not recyclable.
In the liquid state, they can pollute the environment, therefore they must be cured and solidified before disposal according to your country regulation.
