Crystallise, Glaze, Fire – Programming Your F30 Furnace Made Easy

The very first step is to read the official user manual below—this will give you the full picture of how your UP3D F30 furnace is designed to operate. Every furnace has its own quirks and interface, so it's always best to understand the manufacturer's guidance before making changes.


That said, we know you're busy and just need to get up and running—so if you're after the quick version, we've put together a practical TL;DR guide. This includes a real example program, step-by-step instructions, and even a deliberate incompatibility that shows how to work around common limitations in the F30 system.


You’ll also find a sensible compromise that lets you keep your workflow efficient without risking the quality of your restorations. It’s designed to help you understand how each value works, where you can be flexible, and what to prioritise when adapting settings for lithium disilicate, zirconia, or PFM workflows.

Start by selecting a program number. For lithium disilicate, use Program 1, as it’s the first step in the LiSi workflow and typically reserved for this material.

You’ll see the program attributes and curve values—these might look complicated at first, but don’t worry. Here’s a table to help you understand what each value means and the safe limits to work within. You may need to make small compromises to suit your furnace, but minor adjustments won’t affect the final result.

Program Values for F30 Furnace

In our example, we’re using lithium disilicate, which follows this firing cycle:

  1. Preheat at 450 °C for 4 minutes

  2. Ramp to 850 °C at 50 °C/min

  3. Hold at 850 °C for 2 minutes

  4. Cool down to 300 °C at 50 °C/min, with the door opening at 300 °C


So, we'll start by setting the following values in our program:

Code

Value

P

1 (it can be 1 because it's usually our first step)

B

450ºC

S1

4:00

T1

OFF

t1

OFF

H1

BLANK

t2

50ºC/min

T2

850ºC

H2

2:00

V

OFF

VP

BLANK

VH

OFF

LS

400ºC (the program calls for 300ºC but that's outside our available values)

S2

4:00 (it's not called for but a nice slow opening prevents fractures and is more gentle on the furnace)

Now you can go on to add more programs. A good tip is to leave gaps of 10 between each material group—this gives you space to add extra programs later without needing to reorganise everything.


For example: Lithium Disilicate

  • Program 1 – Crystallisation

  • Program 2 – Add-on

  • Program 3 – Stain/Glaze

  • Program 4 – Retouch / Final Glaze


Zirconia

  • Program 11 – Framework Modifier / Opaquer

  • Program 12 - Dentine / Enamel

  • Program 13 - Add-on

  • Program 14 – Stain / Glaze


PFM

  • Program 21 – Opaquer

  • Program 22 - Dentine / Enamel

  • Program 23 - Add-on

  • Program 24 – Stain / Glaze
