Our support site offers a simple visual step-by-step guide for manual sanding, including an optional finish with acrylic spray. Try using a range of sandpaper and micromesh pads with grits from 400 to 12000, in increments of 200, slowly and carefully to clean the lens between grit levels and to eliminate scratches from the previous level before moving on to the next. Instructions: Use a range of incremental sandpaper grits to smooth your surface, then polish the part with acrylic cleaner and a microfiber cloth.Īt around 3000 grit, SLA 3D printed clear parts become glossy and very smooth to the touch. It is, however, very challenging to completely eliminate all layer lines via manual finishing-you may notice micro-scratches when holding the part at a shallow angle to the light. You’ll have to sand to extremely fine grits to manually finish a transparent part, but with some effort, you can sand and polish parts to be as clear as a magnifying glass. It is very difficult to reach total optical transparency with this method. Formlabs and our customers have used Clear Resin to create a completely optically clear lens for a fully 3D printed camera, tiles for a Fresnel lens installation in Times Square, light pipes, prisms, millifluidic devices, and more.Īpplications: Manual sanding and polishing can be effective for simple shapes with few details, but are less suited to finishing complex models. Methods range from quick solutions for adequate transparency, to niche techniques for creating optically clear parts.Ĭlear and transparent 3D prints are ideal for creating clear prototype parts, showing internal cavities and details, housing LEDs, or creating windows. Use the following finishing methods to create transparent 3D printed parts for a variety of applications, from optics to light pipes to fluidics. 3D printing models on the Form 3 in Clear Resin is great for producing parts requiring translucency-and, with the right post-processing techniques, transparency. Special low particle size wax / mineral oil defoamer for better transparency.īest in class non ionic pigment dispersant for all pigment natures.Stereolithography (SLA) 3D printing can create transparent objects that, with some post-processing, can be made optically clear.įormlabs' latest SLA 3D printer, the Form 3, takes clarity one step further by using a flexible resin tank that reduces peel forces, resulting in clearer parts with smooth surface finish. No external emulsification allows better thickener response. High effectiveness silicone defoamer using less amount of silicone. FDA approved, this additive enables reduced levels of pigment dispersant. MODAFLOW® AQ-3025 provides outstanding surface appearance in waterborne paint systems.
