Managing LEDs with NanoDLP

I'm building my own DLP printer with UV LEDs. I use a 20A relay to power them on, since they require high power and can't be directly driven by arduino or Raspberry. I'm planning to use them with NanoDLP on Raspberry + GRBL on Arduino. Is it…

Methylated spirits or turpentine to clean resin printer?

I'm new to 3D printing and have bought a resin printer. Cleaning with Isopropol Alcohol seems to be the rage, however I think this is unaware of cost savings. It appears methylated spirits is ok and is 25% the cost of Isopropol Alcohol. I'm now…

What choices do we have on Clear resins for DLP?

I'm searching for a truly clear DLP resin which can polymerize between 400nm and 405nm. I found the unpigmented from FunToDo, but it seems to be yellow-clear: I'm trying to achieve something similar to this: Is there any resin out there which…

Which photopolymer for printing?

I am thinking about building my own DLP 3D printer. I want to know which uv curing resin I should use. Also, I came across a continuous 3D printing technology where oxygen permeable glass was used to stop the photopolymer toching the glass from…

How to create an accurate mask for a UV 3D resin DLP printer

The light of the build area of a DLP UV printer isn't evenly spread. The source of light is a 9 LED UV array. The light mainly falls of to the sides. This results in objects curing too much in the center, or not enough on the outer sides of the…

What are the other materials which can be used in DLP Printing, other than polymers?

I know that melted polymers are used for DLP (digital light processing) printing, by displaying the model onto the liquid material, which is the melted polymer. But, can I use materials like steel, carbon fiber, etc? If yes, then what precautions…

Photon S DLP first layers adhere but support will not

Recently I changed the FEP bottom of my Anycubic Photon S and I'm having problems with prints now. The bottom layer sticks super well, but none of the supports or the prints do. I've tried tensioning the vat, releveling, and changed supports of the…

How to display images on DLP using HDMI for 3D printing?

I am working on a DLP based 3D printer. I already sliced my STL file to multiple layers. Each layer is saved as a SVG file. Because its an SVG file, I can always convert each layer to PNG/JPG file if desired. I have a TI DLP Lightcrafter 4500…

DLP build plate adhesion

Does anyone have tips on improving build plate adhesion in DLP printers? I've heard a thin layer of resin or UV glue applied to the plate will help, but we're not sure if we leave the resin/glue wet, or cure it before we start the print. Apologies…

Gizmo3D SLA + Monocure resins not curing

I am working with a "Gizmo3D" type DLP resin printer, and using Monocure "General Grey" resin. I'm having some issues with getting this resin to cure to the build plate well enough to prevent it from "wandering" across during the print, without…

Chitubox estimated time very away from the real time

Some time ago, I bought an Elegoo Mars 2 Pro, and I really liked the product. This is my first resin printer and I am very satisfied. What has been bothering me a little is in relation to the slicer. When I slice an item, Chitubox shows 3 hour/20 g…

Top-Down SLA Printer Bulging Issue

I have designed and built a top-down SLA 3D printer that uses a 405 nm 500 mW laser along with some galvanometers. I filled the vat with glycerin and then topped it off with about 2.5 cm of resin. I designed a wiper system for creating an even layer…
