# Overview

::::VerticalSplit{layout="middle"}
:::VerticalSplitItem
The **Dreve PCU LED** uses UV light to cure parts, completing the process started during printing, giving parts their final mechanical properties and making parts safe to handle.&#x20;

It can create a vacuum in the exposure chamber or fill the exposure chamber with nitrogen to aid curing.

# Curing Basics

- LED lamps are located above and below the curing chamber.
- Parts rest on transparent glass platform.&#x20;
- UV light comes from **above and below** and cures most parts without rotating them.

# Features

::::VerticalSplit{layout="middle"}
:::VerticalSplitItem
<font color="#30c49a">**Light sources**</font> on both the top and bottom of chamber allow for consistent curing without the need to flip parts.

The<font color="#05a9f4"> **rotary button**</font> is used to select resin programs, start the curing process and perform administrative tasks.

:::

:::VerticalSplitItem
- Carbon recommends always using the <font color="#05A9F4">**removable glass platform**</font> to cure parts. 
  - This ensures a more uniform cure since parts will be centered between light sources. 
  - Keeps glass right above lower light source free of resin buildup. 
  - **1.5” part height maximum** when using platform. 
- There are 3 different curing environments available: Vacuum, nitrogen and air. 
  - See Exposure Atmospheres below for details.
- LED lamps do not generate heat. So parts may go through multiple cure cycles without pausing for cooling. 
- The unit needs to be configured before use to create the options for proper curing. 
- Go to [Configuring the Dreve PCU LED](docId\:JLgbnwUiOTYwrCRMNPTbk) below.

**Note:** These options cannot be run at the same time.

# Operation

::::VerticalSplit{layout="middle"}
:::VerticalSplitItem
**Note:** Be sure your part is completely dry before curing.

1\. Put on new pair of gloves. 

- Your gloves will be soiled from washing your part. Changing your gloves minimizes resin contamination of the PCU LED and the workspace. 

2\. Insert removable <font color="#30C49A">**glass platform**</font> inside chamber. 

- The glass platform allows for more consistency since parts will be more centered between light sources.&#x20;
- If your Dreve PCU LED box did not include a removable glass platform, please contact [Carbon Support](#).

3\. Turn on the <font color="#05A9F4">**power switch**</font> on the back of the unit

:::
::::

::::VerticalSplit{layout="middle"}
:::VerticalSplitItem
**4.&#x20;**<font color="#30C49A">**Center parts**</font> on removable glass platform. 

- Parts should not touch the sides of the chamber or plastic handle to prevent any uncured surfaces. 
- Parts can be placed close together, but should not overlap or touch other parts. 

5\. Use handle to close the lid. 

**6.&#x20;**<font color="#05A9F4">**Rotate the rotary button**</font> until the proper material program is displayed in white.

:::
::::

::::VerticalSplit{layout="middle"}
:::VerticalSplitItem
7\. Push the <font color="#30C49A">**rotary button twice**</font> to select and start the selected resin program.&#x20;

8\. If a vacuum program has been selected, the pressure indicator will begin decreasing. Once vacuum is achieved (\~150 mbars), the exposure icon and the exposure atmosphere indicator will turn green. At the same time, the clock will begin counting down as the parts in the exposure chamber are cured with light.&#x20;

9\. A green screen with a smiley face will display once the exposure cycle is complete.&#x20;

- If the screen is red, you will need to wait for the vacuum to be released so that you can open the lid without damaging the PCU LED.

## Part Placement

Proper part placement requires that light has a clear path to all part surfaces.&#x20;

- Leave at least 3 mm (0.125 in) around each part to ensure proper curing.&#x20;
- Failure to properly arrange parts will result in partially cured parts that are not fit for use.

# Maintenance

## Daily&#x20;

::::VerticalSplit{layout="middle"}
:::VerticalSplitItem
Wipe glass surfaces <font color="#30C49A">**(platform, lid, and chamber floor)**</font> with IPA and lint-free Kimwipe.&#x20;

- It is very important to avoid residue build-up on these surfaces. Otherwise, the light intensity will be diminished and your parts may not be fully cured.&#x20;

**Note:** Cleaning of glass surfaces should also be performed when switching from one resin to another.
